How to parse HTML with TouchXML or some other alternative.

- by 0SX

Hi, I'm trying to parse the HTML presented below with TouchXML but it keeps crashing when I try to extract certain attributes. I'm totally new to the parser world so I apologize for being a complete idiot. I need help to parse this HTML. What I'm trying to accomplish is to parse each attribute and value or what not and copy them to a string. I've been trying to find a good parser to parse HTML and I believe TouchXML is the best I've seen because of Tidy. Speaking of Tidy, How could I run this HTML through Tidy first then parse it? I'm not sure how to do this. Here is the code that I have so far that doesn't work due to it's not pulling everything I need from the HTML. Any help or advice would be much appreciated. Thanks My current code: NSMutableArray *res = [[NSMutableArray alloc] init]; // using local resource file NSString *XMLPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"example.html"]; NSData *XMLData = [NSData dataWithContentsOfFile:XMLPath]; CXMLDocument *doc = [[[CXMLDocument alloc] initWithData:XMLData options:0 error:nil] autorelease]; NSArray *nodes = NULL; nodes = [doc nodesForXPath:@"//div" error:nil]; for (CXMLElement *node in nodes) { NSMutableDictionary *item = [[NSMutableDictionary alloc] init]; [item setObject:[[node attributeForName:@"id"] stringValue] forKey:@"id"]; [res addObject:item]; [item release]; } NSLog(@"%@", res); [res release]; HTML file that needs to be parsed: <html> <head> <base target="_blank" /> </head> <body style="margin:2;"> <div id="group"> <div id="groupURL"><a href="http://www.example.com/groups">Group URL</a></div> <img id="grouplogo" src="http://images.example.com/groups/image.png" /> <div id="groupcomputer"><a href="http://www.example.com/groups/page" title="Group Title">Group title this would be here</a></div> <div id="groupinfos"> <div id="groupinfo-l">Person</div><div id="groupinfo-r">Ralph</div> <div id="groupinfo-l">Years</div><div id="groupinfo-r">4 years</div> <div id="groupinfo-l">Salary</div><div id="groupinfo-r">100K</div> <div id="groupinfo-l">Other</div><div id="groupoth" style="width:15px">other info</div> </body> </html> EDIT: I could use Element Parser but I need to know how to extract the Person's Name from the following example which would be Ralph in this case. <div id="groupinfo-l">Person</div><div id="groupinfo-r">Ralph</div>

Smart auto detect and replace URLs with anchor tags

- by Robert Koritnik

I've written a regular expression that automatically detects URLs in free text that users enter. This is not such a simple task as it may seem at first. Jeff Atwood writes about it in his post. His regular expression works, but needs extra code after detection is done. I've managed to write a regular expression that does everything in a single go. This is how it looks like (I've broken it down into separate lines to make it more understandable what it does): 1 (?<outer>$)? 2 (?<scheme>http(?<secure>s)?://)? 3 (?<url> 4 (?(scheme) 5 (?:www\.)? 6 | 7 www\. 8 ) 9 [a-z0-9] 10 (?(outer) 11 [-a-z0-9/+&@#/%?=~_()|!:,.;cšžcd]+(?=$) 12 | 13 [-a-z0-9/+&@#/%?=~_()|!:,.;cšžcd]+ 14 ) 15 ) 16 (?<ending>(?(outer)\))) As you may see, I'm using named capture groups (used later in Regex.Replace()) and I've also included some local characters (cšžcd), that allow our localised URL to be parsed as well. You can easily omit them if you'd like. Anyway. Here's what it does (referring to line numbers): 1 - detects if URL starts with open braces (is contained inside braces) and stores it in "outer" named capture group 2 - checks if it starts with URL scheme also detecting whether scheme is SSL or not 3 - starts parsing URL itself (will store it in "url" named capture group) 4-8 - if statement that says: if "sheme" was present then www. part is optional, otherwise mandatory for a string to be a link (so this regular expression detects all strings that start with either http or www) 9 - first character after http:// or www. should be either a letter or a number (this can be extended if you would like to cover even more links, but I've decided to omit other characters because I can't remember a link that would start with some other character 10-14 - if statement that says: if "outer" (braces) was present capture everything up to the last closing braces otherwise capture all 15 - closes the named capture group for URL 16 - if open braces was present, capture closing braces as well and store it in "ending" named capture group First and last line used to have \s* in them as well, so user could also write open braces and put a space inside before pasting link. Anyway. My code that does link replacement with actual anchor HTML elements looks exactly like this: value = Regex.Replace( value, @"(?<outer>$)?(?<scheme>http(?<secure>s)?://)?(?<url>(?(scheme)(?:www\.)?|www\.)[a-z0-9](?(outer)[-a-z0-9/+&@#/%?=~_()|!:,.;cšžcd]+(?=$)|[-a-z0-9/+&@#/%?=~_()|!:,.;cšžcd]+))(?<ending>(?(outer)\)))", "${outer}<a href=\"http${secure}://${url}\">http${secure}://${url}</a>${ending}", RegexOptions.Compiled | RegexOptions.CultureInvariant | RegexOptions.IgnoreCase); As you can see I'm using named capture groups to replace link with an Anchor tag: ${outer}<a href=\"http${secure}://${url}\">http${secure}://${url}</a>${ending} I could as well omit the http(s) part in anchor display to make links look friendlier, but for now I decided not to. Question I would like for my links to be replaced with shortenings as well. So when user copies a very long links (for instance if they would copy a link from google maps that usually generates long links I would like to shorten the visible part of the anchor tag. Link would work, but visible part of an anchor tag would be shortened to some number of characters. Does the replace string support notations like that so I can stil use a singe Regex.Replace() call?

handling long running large transactions with perl dbi

- by 1stdayonthejob

I've got a large transaction comprising of getting lots of data from database A, do some manipulations with this data, then inserting the manipulated data into database B. I've only got permissions to select in database A but I can create tables and insert/update etc in database B. The manipulation and insertion part is written in perl and already in use for loading data into database B from other data sources, so all that's required is to get the necessary data from database A and using it to initialize the perl classes. How can I go about doing this so I can easily track back and pick up from where the error happened if any error occurs during the manipulation or insertion procedures (database disconnection, problems with class initialization because of invalid values, hard disk failure etc...)? Doing the transaction in one go doesn't seem like a good option because the amount data from database A means it would take at least a day or 2 for data manipulation and insertion into database B. The data from database A can be grouped into around 1000 groups using unique keys, with each key containing 1000s of rows each. One way I thought I could do is to write a script that does commits per group, meaning I've got to track which group has already been inserted into database B. The only way I can think of to track the progress of which groups have been processed or not is either in a log file or in a table in database B. A second way I thought could work is to dump all the necessary fields needed for loading the classes for manipulation and insertion into a flatfile, read the file to initialize the classes and insert into database B. This also means that I got to do some logging, but should narrow it down to the exact row in the flatfile if any error occurs. The script will look something like this: use strict; use warnings; use DBI; #connect to database A my $dbh = DBI->connect('dbi:oracle:my_db', $user, $password, { RaiseError => 1, AutoCommit => 0 }); #statement to get data based on group unique key my $sth = $dbh->prepare($my_sql); my @groups; #I have a list of this already open my $fh, '>>', 'my_logfile' or die "can't open logfile $!"; eval { foreach my $g (@groups){ #subroutine to check if group has already been processed, either from log file or from database table next if is_processed($g); $sth->execute($g); my $data = $sth->fetchall_arrayref; #manipulate $data, then use it to load perl classes for insertion into database B #. #. #. } print $fh "$g\n"; }; if ($@){ $dbh->rollback; die "something wrong...rollback"; } So if any errors do occur, I can just run this script again and it should skip the groups or rows that have been processed and continue. Both these methods is just variations on the same theme, and both require going back to where I've been tracking my progress (in table or file), skip the ones that've been commited to database B and process the remaining data. I'm sure there's a better way of doing this but am struggling to think of other solutions. Is there another way of handling large transactions between databases that require data manipulation between getting data out from one and inserting into another? The process doesn't need to be all in Perl, as long as I can reuse the perl classes for manipulating and inserting the data into the database.

Why does adding a Flex DateChooser component throw an index out of bounds error?

- by Lo'

I'm facing an issue with the flex Application I'm currently working on.

It's really weird because I didn't have this issue until this morning. All I did in the meantime was changing some layout-related stuff, but I don't see what is would have to do with this problem. I don't get it... Does anyone have a clue about how to fix this ? I need my DateChooser ! Thanks ! Laura EDIT - It seems that the problem is not caused by the DateChooser itself, but by the FormItem around it. Here's what my code looks like : <Form width="100%"> [...] <s:HGroup width="100%"> <s:FormItem label="Date de début"> <mx:DateChooser id="startDate" firstDayOfWeek="1"/> </s:FormItem> <s:FormItem label="Date de fin"> <mx:DateChooser id="endDate" firstDayOfWeek="1"/> </s:FormItem> </s:HGroup> </Form> If I remove the two FormItems, it works. Could anyone explain me why? Thanks !

XSLT: a variation on the pagination problem

- by MarcoS

I must transform some XML data into a paginated list of fields. Here is an example. Input XML: <?xml version="1.0" encoding="UTF-8"?> <data> <books> <book title="t0"/> <book title="t1"/> <book title="t2"/> <book title="t3"/> <book title="t4"/> </books> <library name="my library"/> </data> Desired output: <?xml version="1.0" encoding="UTF-8"?> <pages> <page number="1"> <field name="library_name" value="my library"/> <field name="book_1" value="t0"/> <field name="book_2" value="t1"/> </page> <page number="2"> <field name="book_1" value="t2"/> <field name="book_2" value="t3"/> </page> <page number="3"> <field name="book_1" value="t4"/> </page> </pages> In the above example I assume that I want at most 2 fields named book_n (with n ranging between 1 and 2) per page. Tags <page> must have an attribute number. Finally, the field named library_name must appear only the first <page>. Here is my current solution using XSLT: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0" exclude-result-prefixes="trx xs"> <xsl:output method="xml" indent="yes" omit-xml-declaration="no" /> <xsl:variable name="max" select="2"/> <xsl:template match="//books"> <xsl:for-each-group select="book" group-ending-with="*[position() mod $max = 0]"> <xsl:variable name="pageNum" select="position()"/> <page number="{$pageNum}"> <xsl:for-each select="current-group()"> <xsl:variable name="idx" select="if (position() mod $max = 0) then $max else position() mod $max"/> <field value="{@title}"> <xsl:attribute name="name">book_<xsl:value-of select="$idx"/> </xsl:attribute> </field> </xsl:for-each> <xsl:if test="$pageNum = 1"> <xsl:call-template name="templateFor_library"/> </xsl:if> </page> </xsl:for-each-group> </xsl:template> <xsl:template name="templateFor_library"> <xsl:for-each select="//library"> <field name="library_name" value="{@name}" /> </xsl:for-each> </xsl:template> </xsl:stylesheet> Is there a better/simpler way to perform this transformation?

Why does Saxon evaluate the result-document URI to be the same?

- by Jan

My XSL source document looks like this <Topology> <Environment> <Id>test</Id> <Machines> <Machine> <Id>machine1</Id> <modules> <module>m1</module> <module>m2</module> </modules> </Machine> </Machines> </Environment> <Environment> <Id>production</Id> <Machines> <Machine> <Id>machine1</Id> <modules> <module>m1</module> <module>m2</module> </modules> </Machine> <Machine> <Id>machine2</Id> <modules> <module>m3</module> <module>m4</module> </modules> </Machine> </Machines> </Environment> </Topology> I want to create one result-document per machine, so I use the following stylesheet giving modelDir as path for the result-documents as parameter. <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" name="myXML" doctype-system="http://java.sun.com/dtd/properties.dtd"/> <xsl:template match="/"> <xsl:for-each-group select="/Topology/Environment/Machines/Machine" group-by="Id"> <xsl:variable name="machine" select="Id"/> <xsl:variable name="filename" select="concat($modelDir,$machine,'.xml')" /> <xsl:message terminate="no">Writing machine description to <xsl:value-of select="$filename"/></xsl:message> <xsl:result-document href="$filename" format="myXML"> <xsl:variable name="currentMachine" select="Id"/> <xsl:for-each select="current-group()/LogicalHosts/LogicalHost"> <xsl:variable name="environment" select="normalize-space(../../../../Id)"/> <xsl:message terminate="no">Module <xsl:value-of select="."/> for <xsl:value-of select="$environment"/></xsl:message> </xsl:for-each> </xsl:result-document> </xsl:for-each-group> </xsl:template> As my messages show me this seems to work fine - if saxon would not evaluate the URI of the result-document to be the same and thus give the following output.

Question I would like my links to be replaced with shortenings as well. So when user copies a very long link (for instance if they would copy a link from google maps that usually generates long links) I would like to shorten the visible part of the anchor tag. Link would work, but visible part of an anchor tag would be shortened to some number of characters. I could as well append ellipsis at the end of at all possible (and make things even more perfect). Does Regex.Replace() method support replacement notations so that I can still use a single call? Something similar as string.Format() method does when you'd like to format values in string format (decimals, dates etc...).

Data munging and data import scripting

- by morpheous

I need to write some scripts to carry out some tasks on my server (running Ubuntu server 8.04 TLS). The tasks are to be run periodically, so I will be running the scripts as cron jobs. I have divided the tasks into "group A" and "group B" - because (in my mind at least), they are a bit different. Task Group A import data from a file and possibly reformat it - by reformatting, I mean doing things like santizing the data, possibly normalizing it and or running calculations on 'columns' of the data Import the munged data into a database. For now, I am mostly using mySQL for the vast majority of imports - although some files will be imported into a sqlLite database. Note: The files will be mostly text files, although some of the files are in a binary format (my own proprietary format, written by a C++ application I developed). Task Group B Extract data from the database Perform calculations on the data and either insert or update tables in the database. My coding experience is is primarily as a C/C++ developer, although I have been using PHP as well for the last 2 years or so. I am from a windows background so I am still finding my feet in the linux environment. My question is this - I need to write scripts to perform the tasks I described above. Although I suppose I could write a few C++ applications to be used in the shell scripts, I think it may be better to write them in a scripting language (maybe this is a flawed assumption?). My thinking is that it would be easier to modify thins in a script - no need to rebuild etc for changes to functionality. Additionally, C++ data munging in C++ tends to involve more lines of code than "natural" scripting languages such as Perl, Python etc. Assuming that the majority of people on here agree that scripting is the way to go, herein lies my dilema. Which scripting language to use to perform the tasks above (giving my background). My gut instinct tells me that Perl (shudder) would be the most obvious choice for performing all of the above tasks. BUT (and that is a big BUT). The mere mention of Perl makes my toes curl, as I had a very, very bag experience with it a while back. The syntax seems quite unnatural to me - despite how many times I have tried to learn it - so if possible, I would really like to give it a miss. PHP (which I already know), also am not sure is a good candidate for scripting on the CLI (I have not seen many examples on how to do this etc - so I may be wrong). The last thing I must mention is that IF I have to learn a new language in order to do this, I cannot afford (time constraint) to spend more than a day, in learning the key commands/features required in order to do this (I can always learn the details of the language later, once I have actually deployed the scripts). So, which scripting language would you recommend (PHP, Python, Perl, [insert your favorite here]) - and most importantly WHY?. Or, should I just stick to writing little C++ applications that I call in a shell script?. Lastly, if you have suggested a scripting language, can you please show with a FEW lines (Perl mongers - I'm looking in your direction [nothing to cryptic!] ;) ) how I can use the language you suggested to do what I want to do. Hopefully, the lines you present will convince me that it can be done easily and elegantly in the language you suggested.

Receiving Multicast Messages on a Multihomed Windows PC

- by Basti

I'm developing a diagnostic tool on a PC with several Network Interfaces based on multicast/udp. The user can select a NIC, the application creates sockets, binds them to this NIC and adds them to the specific multicast group. The sending of multicast messages works fine. However receiving of messages only succeeds if I bind the sockets to a specific NIC of my PC. It almost looks like as there is a 'default' NIC for receiving multicast messages in Windows which is always the first NIC returned by the GetAdapterInfo function. I monitored the network with Wireshark and discovered that the "IGMP Join Group" message isn't sent from the NIC I bound the socket at, but by this 'default' NIC. If I disable this NIC (or remove the network cable), the next NIC of the list returned by GetAdapterInfo is used for receiving multicast messages. I was successful to change this 'default' NIC by adding an additional entry to the routing table of my PC, but I don't think this is a good solution of the problem. The problem also occurs with the code appended below. The join group messages isn't sent via 192.168.52 but via a different NIC. // socket_tst.cpp : Defines the entry point for the console application. // #include tchar.h #include winsock2.h #include ws2ipdef.h #include IpHlpApi.h #include IpTypes.h #include stdio.h int _tmain(int argc, _TCHAR* argv[]) { WSADATA m_wsaData; SOCKET m_socket; sockaddr_in m_sockAdr; UINT16 m_port = 319; u_long m_interfaceAdr = inet_addr("192.168.1.52"); u_long m_multicastAdr = inet_addr("224.0.0.107"); int returnValue = WSAStartup(MAKEWORD(2,2), &m_wsaData); if (returnValue != S_OK) { return returnValue; } // Create sockets if (INVALID_SOCKET == (m_socket = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP)) ) { return WSAGetLastError(); } int doreuseaddress = TRUE; if (setsockopt(m_socket,SOL_SOCKET,SO_REUSEADDR,(char*) &doreuseaddress,sizeof(doreuseaddress)) == SOCKET_ERROR) { return WSAGetLastError(); } // Configure socket addresses memset(&m_sockAdr,0,sizeof(m_sockAdr)); m_sockAdr.sin_family = AF_INET; m_sockAdr.sin_port = htons(m_port); m_sockAdr.sin_addr.s_addr = m_interfaceAdr; //bind sockets if ( bind( m_socket, (SOCKADDR*) &m_sockAdr, sizeof(m_sockAdr) ) == SOCKET_ERROR ) { return WSAGetLastError(); } // join multicast struct ip_mreq_source imr; memset(&imr,0,sizeof(imr)); imr.imr_multiaddr.s_addr = m_multicastAdr; // address of multicastgroup imr.imr_sourceaddr.s_addr = 0; // sourceaddress (not used) imr.imr_interface.s_addr = m_interfaceAdr; // interface address /* first join multicast group, then registerer selected interface as * multicast sending interface */ if( setsockopt( m_socket ,IPPROTO_IP ,IP_ADD_MEMBERSHIP ,(char*) &imr , sizeof(imr)) == SOCKET_ERROR) { return SOCKET_ERROR; } else { if( setsockopt(m_socket ,IPPROTO_IP ,IP_MULTICAST_IF ,(CHAR*)&imr.imr_interface.s_addr ,sizeof(&imr.imr_interface.s_addr)) == SOCKET_ERROR ) { return SOCKET_ERROR; } } printf("receiving msgs...\n"); while(1) { // get inputbuffer from socket int sock_return = SOCKET_ERROR; sockaddr_in socketAddress; char buffer[1500]; int addressLength = sizeof(socketAddress); sock_return = recvfrom(m_socket, (char*) &buffer, 1500, 0, (SOCKADDR*)&socketAddress, &addressLength ); if( sock_return == SOCKET_ERROR) { int wsa_error = WSAGetLastError(); return wsa_error; } else { printf("got message!\n"); } } return 0; } Thanks four your help!

Projections.count() and Projections.countDistinct() both result in the same query

- by Kim L

EDIT: I've edited this post completely, so that the new description of my problem includes all the details and not only what I previously considered relevant. Maybe this new description will help to solve the problem I'm facing. I have two entity classes, Customer and CustomerGroup. The relation between customer and customer groups is ManyToMany. The customer groups are annotated in the following way in the Customer class. @Entity public class Customer { ... @ManyToMany(mappedBy = "customers", fetch = FetchType.LAZY) public Set<CustomerGroup> getCustomerGroups() { ... } ... public String getUuid() { return uuid; } ... } The customer reference in the customer groups class is annotated in the following way @Entity public class CustomerGroup { ... @ManyToMany public Set<Customer> getCustomers() { ... } ... public String getUuid() { return uuid; } ... } Note that both the CustomerGroup and Customer classes also have an UUID field. The UUID is a unique string (uniqueness is not forced in the datamodel, as you can see, it is handled as any other normal string). What I'm trying to do, is to fetch all customers which do not belong to any customer group OR the customer group is a "valid group". The validity of a customer group is defined with a list of valid UUIDs. I've created the following criteria query Criteria criteria = getSession().createCriteria(Customer.class); criteria.setProjection(Projections.countDistinct("uuid")); criteria = criteria.createCriteria("customerGroups", "groups", Criteria.LEFT_JOIN); List<String> uuids = getValidUUIDs(); Criterion criterion = Restrictions.isNull("groups.uuid"); if (uuids != null && uuids.size() > 0) { criterion = Restrictions.or(criterion, Restrictions.in( "groups.uuid", uuids)); } criteria.add(criterion); When executing the query, it will result in the following SQL query select count(*) as y0_ from Customer this_ left outer join CustomerGroup_Customer customergr3_ on this_.id=customergr3_.customers_id left outer join CustomerGroup groups1_ on customergr3_.customerGroups_id=groups1_.id where groups1_.uuid is null or groups1_.uuid in ( ?, ? ) The query is exactly what I wanted, but with one exception. Since a Customer can belong to multiple CustomerGroups, left joining the CustomerGroup will result in duplicated Customer objects. Hence the count(*) will give a false value, as it only counts how many results there are. I need to get the amount of unique customers and this I expected to achieve by using the Projections.countDistinct("uuid"); -projection. For some reason, as you can see, the projection will still result in a count(*) query instead of the expected count(distinct uuid). Replacing the projection countDistinct with just count("uuid") will result in the exactly same query. Am I doing something wrong or is this a bug? === "Problem" solved. Reason: PEBKAC (Problem Exists Between Keyboard And Chair). I had a branch in my code and didn't realize that the branch was executed. That branch used rowCount() instead of countDistinct().

RadioGroup onCheckedChanged function won't fire

- by user1758088

First time/long time. My app keeps track of restaurant servers' shift sales to help them budget. In the activity that displays past shifts, I've created a RadioGroup under the ListView so the server can choose lunch, dinner, or both. I've implemented RadioGroup.onCheckedChangeListener, but onCheckChanged never gets called. I also tried an anonymous inner class as listener, same result. I tried to copy/modify code from this answer: http://stackoverflow.com/a/9595528 ...but when I added the @Override to the callback function, the Eclipse compiler gave me an error (not warning) that the method must override a superclass, and the quick fix was to remove the override. I'm pretty sure the signatures are correct, as they were made with Eclipse's autocomplete and implement methods facilities. I then followed instructions to move my java compiler from 1.5 to 1.6, and none of the above listed behavior seemed to change. Here's the code I thing is relavent: public class DataActivity extends ListActivity implements OnCheckedChangeListener{ RadioButton rbBoth; RadioButton rbDinnerOnly; RadioButton rbLunchOnly; @Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.database); ... final RadioGroup rgGroup = (RadioGroup)findViewById(R.id.DataRadioGroup); rbBoth = (RadioButton)findViewById(R.id.RadioBoth); rbDinnerOnly = (RadioButton)findViewById(R.id.RadioDinnerOnly); rbLunchOnly = (RadioButton)findViewById(R.id.RadioLunchOnly); rgGroup.setOnCheckedChangeListener(this); populateAllShifts(); } ... public void onCheckedChanged(RadioGroup group, int checkedId) { rbLunchOnly.setText("Click!"); Toast.makeText(getApplicationContext(), "Lunch Only", Toast.LENGTH_LONG).show(); if(group.getCheckedRadioButtonId() == R.id.RadioBoth){ populateAllShifts(); return; } if(group.getCheckedRadioButtonId() == R.id.RadioLunchOnly){ populatLunchShifts(); return; } if(group.getCheckedRadioButtonId() == R.id.RadioDinnerOnly){ populateDinnerShifts(); return; } } There is a ListView in this class with a custom adapter, but if my understanding and my XML are correct, the RadioGroup should be outside of the list: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/llDataLayout" android:weightSum="5" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <ListView android:layout_weight="4" android:layout_width="fill_parent" android:id="@android:id/list" android:layout_height="wrap_content"></ListView> <RadioGroup android:layout_weight="1" android:id="@+id/DataRadioGroup" android:orientation="horizontal" android:layout_height="wrap_content" android:layout_width="fill_parent"> <RadioButton android:text="Lunch and Dinner" android:textSize="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/RadioBoth"/> <RadioButton android:text="Dinner Only" android:textSize="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/RadioDinnerOnly"/> <RadioButton android:text="Lunch Only" android:textSize="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/RadioLunchOnly"/> </RadioGroup> </LinearLayout> Any ideas out there?

Elements of website don't work in IE

- by mjcuva

On the site I'm working on for my high school basketball team, certain elements don't work in Internet Explorer. The site is hermantownbasketball.com. The boys basketball sidebar should have nested drop down menus, one when you mouse over the team, such as "High School" and then another when you mouse over the grade under the team, such as 9th grade. This works perfectly fine in chrome, however, I can't get it to work in any version of Internet Explorer. Below is the part of the html and the corresponding css I am using. Unfortunately, I don't know enough css to know which part of my code IE doesn't like or how to fix it. Any help is greatly appreciated! HTML <span class = "boyItem"> <h3>High School</h3> <li class="group"> <h4>9th Grade</h4> <div class = "nested">Schedule</div> <div class = "nested">Events</div> <div class ="nested">Forms</div> <div class ="nested">Calendar</div> </li> <li class="group"> <h4>JV/Varsity</h4> <div class = "nested">Schedule</div> <div class = "nested">Events</div> <div class = "nested">Forms</div> <div class = "nested">Calendar</div> </li> </span> /* Creates the box around the title for each boy section. */ .boyItem h3 { background:#1C23E8; color:#EFFA20; padding-right:2px; padding:10px; font-size:18px; margin-left:-30px; margin-top:-10px; } ###CSS .boyItem h3:hover { background:#2A8FF5; } /* Prevents the boy sub-sections from being visable */ .boyItem li h4 { position: absolute; left:-9999px; font-size:15px; list-style-type:none;} /* Shows the boy sub-sections when user mouses over the section title. */ .boyItem:hover li h4 { position:relative; left:10px; background:#1C23E8; color:#EFFA20; padding-left:20px; padding:5px; } .boyItem:hover li h4:hover { background:#2A8FF5;} .nested { position:absolute; left:-9999px; background:#352EFF; color:#EFFA20; padding-right:2px; padding:4px; font-size:14px; margin:2px; margin-left:30px; margin-top:0px; margin-right:0px; margin-bottom:-2px;} .group:hover .nested {position:relative; left:0px; } .group:hover .nested:hover { background:#2A8FF5}

current_user and Comments on Posts - Create another association or loop posts? - Ruby on Rails

- by bgadoci

I have created a blog application using Ruby on Rails and have just added an authentication piece and it is working nicely. I am now trying to go back through my application to adjust the code such that it only shows information that is associated with a certain user. Currently, Users has_many :posts and Posts has_many :comments. When a post is created I am successfully inserting the user_id into the post table. Additionally I am successfully only displaying the posts that belong to a certain user upon their login in the /views/posts/index.html.erb view. My problem is with the comments. For instance on the home page, when logged in, a user will see only posts that they have written, but comments from all users on all posts. Which is not what I want and need some direction in correcting. I want only to display the comments written on all of the logged in users posts. Do I need to create associations such that comments also belong to user? Or is there a way to adjust my code to simply loop through post to display this data. I have put the code for the PostsController, CommentsController, and /posts/index.html.erb below and also my view code but will post more if needed. class PostsController < ApplicationController before_filter :authenticate auto_complete_for :tag, :tag_name auto_complete_for :ugtag, :ugctag_name def index @tag_counts = Tag.count(:group => :tag_name, :order => 'count_all DESC', :limit => 20) conditions, joins = {}, :votes @ugtag_counts = Ugtag.count(:group => :ugctag_name, :order => 'count_all DESC', :limit => 20) conditions, joins = {}, :votes @vote_counts = Vote.count(:group => :post_title, :order => 'count_all DESC', :limit => 20) conditions, joins = {}, :votes unless(params[:tag_name] || "").empty? conditions = ["tags.tag_name = ?

Python regex to parse text file, get the items in list and count the list

- by Nemo

I have a text file which contains some data. I m particularly interested in finding the count of the number of items in v_dims v_dims pattern in my text file looks like this : v_dims={ "Sales", "Product Family", "Sales Organization", "Region", "Sales Area", "Sales office", "Sales Division", "Sales Person", "Sales Channel", "Sales Order Type", "Sales Number", "Sales Person", "Sales Quantity", "Sales Amount" } So I m thinking of getting all the elements in v_dims and dumping them out in a Python list. Then compute the len(mylist) to get the count of the items. The challenge is in getting all the elements of v_dims from my text file and putting them in an empty list. I m particularly interested in items in v_dims in my text file. The text file has data in the form of v_dims pattern i showed in my original post. Some data has nested patterns of v_dims. Thanks. Here's what I have tried and failed. Any help is appreciated. TIA. import re fname = "C:\Users\XXXX\Test.mrk" with open(fname, "r") as fo: content_as_string = fo.read() match = re.findall(r'v_dims={\"(.+?)\"}',content_as_string) Though I have a big text file,

ORDER BY job failed in the Pig script while running EmbeddedPig using Java

- by C.c. Huang

I have this following pig script, which works perfectly using grunt shell (stored the results to HDFS without any issues); however, the last job (ORDER BY) failed if I ran the same script using Java EmbeddedPig. If I replace the ORDER BY job by others, such as GROUP or FOREACH GENERATE, the whole script then succeeded in Java EmbeddedPig. So I think it's the ORDER BY which causes the issue. Anyone has any experience with this? Any help would be appreciated! The Pig script: REGISTER pig-udf-0.0.1-SNAPSHOT.jar; user_similarity = LOAD '/tmp/sample-sim-score-results-31/part-r-00000' USING PigStorage('\t') AS (user_id: chararray, sim_user_id: chararray, basic_sim_score: float, alt_sim_score: float); simplified_user_similarity = FOREACH user_similarity GENERATE $0 AS user_id, $1 AS sim_user_id, $2 AS sim_score; grouped_user_similarity = GROUP simplified_user_similarity BY user_id; ordered_user_similarity = FOREACH grouped_user_similarity { sorted = ORDER simplified_user_similarity BY sim_score DESC; top = LIMIT sorted 10; GENERATE group, top; }; top_influencers = FOREACH ordered_user_similarity GENERATE com.aol.grapevine.similarity.pig.udf.AssignPointsToTopInfluencer($1, 10); all_influence_scores = FOREACH top_influencers GENERATE FLATTEN($0); grouped_influence_scores = GROUP all_influence_scores BY bag_of_topSimUserTuples::user_id; influence_scores = FOREACH grouped_influence_scores GENERATE group AS user_id, SUM(all_influence_scores.bag_of_topSimUserTuples::points) AS influence_score; ordered_influence_scores = ORDER influence_scores BY influence_score DESC; STORE ordered_influence_scores INTO '/tmp/cc-test-results-1' USING PigStorage(); The error log from Pig: 12/04/05 10:00:56 INFO pigstats.ScriptState: Pig script settings are added to the job 12/04/05 10:00:56 INFO mapReduceLayer.JobControlCompiler: mapred.job.reduce.markreset.buffer.percent is not set, set to default 0.3 12/04/05 10:00:58 INFO mapReduceLayer.JobControlCompiler: Setting up single store job 12/04/05 10:00:58 INFO jvm.JvmMetrics: Cannot initialize JVM Metrics with processName=JobTracker, sessionId= - already initialized 12/04/05 10:00:58 INFO mapReduceLayer.MapReduceLauncher: 1 map-reduce job(s) waiting for submission. 12/04/05 10:00:58 WARN mapred.JobClient: Use GenericOptionsParser for parsing the arguments.

NetUserGetLocalGroups - how to call it?

- by SteveL

Hi, I am using Delphi 2010, latest version (from repository) of JEDI WinAPI and Windows Security Code Library (WSCL). I don't know how to call the NetUserSetGroups function. The way I am doing it, it is throwing an exception: Access violation at address 5B8760BE in module 'netapi32.dll'. Write of address 00000000. Following is my code: unit uFunc; interface uses Windows, SysUtils, JwaWindows, JwsclSid, Classes; function UserExists(const username: PChar): boolean; stdcall; function AddUser(const username, password: PChar;

MVC 3 ModelView passing parameters between view & controller

- by Tobias Vandenbempt

I've been playing with MVC 3 in a test project and have the following issue. I have Group & Subscriber entities and those are coupled through a SubscriberGroup table. Using the DetailView of Group I open a view of SubscriberGroup containing all subscribers. This list has the option to filter. So far it all works, however when I call the AddToGroup method on the controller it fails. Specifically it goes into the method but doesn't pass the subscriberCheckedModels list. Am I doing something wrong? View: SubscriberGroup Index.aspx <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.master" Inherits="System.Web.Mvc.ViewPage<Mail.Models.SubscriberCheckedListViewModel>" %> … <h2 class="common-box-title"> Add Subscribers to Group</h2> <p> <% using (Html.BeginForm("Index", "SubscriberGroup")) { %> <input name="filter" id="filter" type="text" /> <input type="submit" value="Search" /> <%} %> </p> <% using (Html.BeginForm("AddToGroup", "SubscriberGroup", Model,FormMethod.Get, null)) { %> <fieldset> <div style="display: inline-block; width: 70%; vertical-align: top;"> <% if (Model.subscribers.Count() != 0) { %> <table class="hor-minimalist-b"> <tr> <th> Add To Group </th> <th> Full Name </th> <th> Email </th> <th> Customer </th> </tr> <% foreach (var item in Model.subscribers) { %> <tr> <td> <%= Html.CheckBoxFor(modelItem => item.AddToGroup)%> </td> <td> <%= Html.DisplayFor(modelItem => item.subscriber.LastName)%> <%= Html.ActionLink(item.subscriber.FirstName + " " + item.subscriber.LastName, "Details", new { id = item.subscriber.SubscriberID })%> </td> <td> <%: Html.DisplayFor(modelItem => item.subscriber.Email)%> </td> <td> <%: Html.DisplayFor(modelItem => item.subscriber.Customer.Company)%> <%= Html.HiddenFor(modelItem => item.subscriber) %> </td> </tr> <% } %> <% ViewBag.subscribers = Model.subscribers; %> probeersel <%= Html.HiddenFor(model => model.subscribers) %> probeersel </table> <%} %> <%else { %> <p> No subscribers found.</p> <%} %> <input type="submit" value="Add Subscribers" /> </div> </fieldset> <%} %> Controller: SubscriberGroupController using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Web.Security; using Mail.Models; namespace Mail.Controllers { public class SubscriberGroupController : Controller { private int groupID; private MailDBEntities db = new MailDBEntities(); // // GET: /SubscriberGroup/ public ActionResult Index(int id) { groupID = id; MembershipUser myObject = Membership.GetUser(); Guid UserID = Guid.Parse(myObject.ProviderUserKey.ToString()); UserCustomer usercustomer = db.UserCustomers.Single(s => s.UserID == UserID); var subscribers = from subscriber in db.Subscribers where (subscriber.CustomerID == usercustomer.CustomerID) | (subscriber.CustomerID == 0) select new SubscriberCheckedModel { subscriber = subscriber, AddToGroup = false }; SubscriberCheckedListViewModel test = new SubscriberCheckedListViewModel(); test.subscribers = subscribers; return View(test); } [HttpPost] public ActionResult Index(string filter) { MembershipUser myObject = Membership.GetUser(); Guid UserID = Guid.Parse(myObject.ProviderUserKey.ToString()); UserCustomer usercustomer = db.UserCustomers.Single(s => s.UserID == UserID); var subscribers2 = from subscriber in db.Subscribers where ((subscriber.FirstName.Contains(filter)|| subscriber.LastName.Contains(filter)) && (subscriber.CustomerID == usercustomer.CustomerID || subscriber.CustomerID == 0)) select new SubscriberCheckedModel { subscriber = subscriber, AddToGroup = false }; SubscriberCheckedListViewModel test = new SubscriberCheckedListViewModel(); test.subscribers = subscribers2.ToList(); return View(test); } [HttpPost] public ActionResult AddToGroup(SubscriberCheckedListViewModel test) { //test is null return RedirectToAction("Details", "Group", new { id = groupID }); } } } ViewModel: SubscriberGroupModel using System.Collections.Generic; using Mail; namespace Mail.Models { public class SubscriberCheckedModel { public Subscriber subscriber { get; set; } public bool AddToGroup { get; set; } } public class SubscriberCheckedListViewModel { public IEnumerable<SubscriberCheckedModel> subscribers { get; set; } } }

Map a Network Drive from XP to Windows 7

- by Mysticgeek

We’ve received a lot of questions about mapping a drive from XP to Windows 7 to access data easily. Today we look at how to map a drive in Windows 7, and how to map to an XP drive from Windows 7. With the new Homegroup feature in Windows 7, it makes sharing data between computers a lot easier. But you might need to map a network drive so you can go directly into a folder to access its contents. Mapping a network drive may sound like “IT talk”, but the process is fairly easy. Map Network Drive in Windows 7 Note: All of the computers used in this article are part of the same workgroup on a home network. In this first example we’re mapping to another Windows 7 drive on the network. Open Computer and from the toolbar click on Map Network Drive. Alternately in Computer you can hit “Alt+T” to pull up the toolbar and click on Tools \ Map Network Drive. Now give it an available drive letter, type in the path or browse to the folder you want to map to. Check the box next to Reconnect at logon if you want it available after a reboot, and click Finish. If both machines aren’t part of the same Homegroup, you may be prompted to enter in a username and password. Make sure and check the box next to Remember my credentials if you don’t want to log in every time to access it. The drive will map and the contents of the folder will open up. When you look in Computer, you’ll see the drive under network location. This process works if you want to connect to a server drive as well. In this example we map to a Home Server drive. Map an XP Drive to Windows 7 There might be times when you need to map a drive on an XP machine on your network. There are extra steps you’ll need to take to make it work however. Here we take a look at the problem you’ll encounter when trying to map to an XP machine if things aren’t set up correctly. If you try to browse to your XP machine you’ll see a message that you don’t have permission. Or if you try to enter in the path directly, you’ll be prompted for a username and password, and the annoyance is, no matter what credentials you put in, you can’t connect. To solve the problem we need to set up the Windows 7 machine as a user on the XP machine and make them part of the Administrators group. Right-click My Computer and select Manage. Under Computer Management expand Local Users and Groups and click on the Users folder. Right-click an empty area and click New User. Add in the user credentials, uncheck User must change password at next logon, then check Password never expires then click Create. Now you see the new user you created in the list. After the user is added you might want to reboot before proceeding to the next step. Next we need to make the user part of the Administrators group. So go back into Computer Management \ Local Users and Groups \ Groups then double click on Administrators. Click the Add button in Administrators Properties window. Enter in the new user you created and click OK. An easy way to do this is to enter the name of the user you created then click Check Names and the path will be entered in for you. Now you see the user as a member of the Administrators group. Back on the Windows 7 machine we’ll start the process of mapping a drive. Here we’re browsing to the XP Media Center Edition machine. Now we can enter in the user name and password we just created. If you only want to access specific shared folders on the XP machine you can browse to them. Or if you want to map to the entire drive, enter in the drive path where in this example it’s “\\XPMCE\C$” –Don’t forget the “$” sign after the local drive letter. Then login… Again the contents of the drive will open up for you to access. Here you can see we have two drives mapped. One to another Windows 7 machine on the network, and the other one to the XP computer. If you ever want to disconnect a drive, just right-click on it and then Disconnect. There are several scenarios where you might want to map a drive in Windows 7 to access specific data. It takes a little bit of work but you can map to an XP drive from Windows 7 as well. This comes in handy where you have a network with different versions of Windows running on it.

Security in OBIEE 11g, Part 2

- by Rob Reynolds

Continuing the series on OBIEE 11g, our guest blogger this week is Pravin Janardanam. Here is Part 2 of his overview of Security in OBIEE 11g. OBIEE 11g Security Overview, Part 2 by Pravin Janardanam In my previous blog on Security, I discussed the OBIEE 11g changes regarding Authentication mechanism, RPD protection and encryption. This blog will include a discussion about OBIEE 11g Authorization and other Security aspects. Authorization: Authorization in 10g was achieved using a combination of Users, Groups and association of privileges and object permissions to users and Groups. Two keys changes to Authorization in OBIEE 11g are: Application Roles Policies / Permission Groups Application Roles are introduced in OBIEE 11g. An application role is specific to the application. They can be mapped to other application roles defined in the same application scope and also to enterprise users or groups, and they are used in authorization decisions. Application roles in 11g take the place of Groups in 10g within OBIEE application. In OBIEE 10g, any changes to corporate LDAP groups require a corresponding change to Groups and their permission assignment. In OBIEE 11g, Application roles provide insulation between permission definitions and corporate LDAP Groups. Permissions are defined at Application Role level and changes to LDAP groups just require a reassignment of the Group to the Application Roles. Permissions and privileges are assigned to Application Roles and users in OBIEE 11g compared to Groups and Users in 10g. The diagram below shows the relationship between users, groups and application roles. Note that the Groups shown in the diagram refer to LDAP Groups (WebLogic Groups by default) and not OBIEE application Groups. The following screenshot compares the permission windows from Admin tool in 10g vs 11g. Note that the Groups in the OBIEE 10g are replaced with Application Roles in OBIEE 11g. The same is applicable to OBIEE web catalog objects. The default Application Roles available after OBIEE 11g installation are BIAdministrator, BISystem, BIConsumer and BIAuthor. Application policies are the authorization policies that an application relies upon for controlling access to its resources. An Application Role is defined by the Application Policy. The following screenshot shows the policies defined for BIAdministrator and BISystem Roles. Note that the permission for impersonation is granted to BISystem Role. In OBIEE 10g, the permission to manage repositories and Impersonation were assigned to “Administrators” group with no control to separate these permissions in the Administrators group. Hence user “Administrator” also had the permission to impersonate. In OBI11g, BIAdministrator does not have the permission to impersonate. This gives more flexibility to have multiple users perform different administrative functions. Application Roles, Policies, association of Policies to application roles and association of users and groups to application roles are managed using Fusion Middleware Enterprise Manager (FMW EM). They reside in the policy store, identified by the system-jazn-data.xml file. The screenshots below show where they are created and managed in FMW EM. The following screenshot shows the assignment of WebLogic Groups to Application Roles. The following screenshot shows the assignment of Permissions to Application Roles (Application Policies). Note: Object level permission association to Applications Roles resides in the RPD for repository objects. Permissions and Privilege for web catalog objects resides in the OBIEE Web Catalog. Wherever Groups were used in the web catalog and RPD has been replaced with Application roles in OBIEE 11g. Following are the tools used in OBIEE 11g Security Administration: · Users and Groups are managed in Oracle WebLogic Administration console (by default).

The credential store contains credentials that either user supplied or system generated. Credential store in OBIEE 10g is file based and is managed using cryptotools utility. In 11g, Credential store can be managed directly from the FMW Enterprise Manager and is stored in cwallet.sso file. By default, the Credential Store stores password for deployed RPDs, BI Publisher data sources and BISystem user. In addition, Credential store can be LDAP based but only Oracle Internet Directory is supported right now. As you can see OBIEE security is integrated with Oracle Fusion Middleware security architecture. This provides a common security framework for all components of Business Intelligence and Fusion Middleware applications.
