• how to get unique values set from a repeating values list

  - by Mariselvam

  I need to parse a large log file (flat file), which contains two column of values (column-A , column-B). Values in both columns are repeating. I need to find for each unique value in column-A , I need to find a set of column-B values. Is this can be done using unix shell command or need to write any perl or python script? What are the ways this can be done? Example: xxxA 2 xxxA 1 xxxB 2 XXXC 3 XXXA 3 xxxD 4 output: xxxA - 2,1,3 xxxB - 2 xxxC - 3 xxxD - 4

• Determine if e-mail message can be successfully sent

  - by Felipe Lima

  Hello Everyone, I am working in a mailing application in C# and, basically, I need to be able to determine which recipients successfully received the message, which ones did not, no matter what was the failure reason. In summary, I need an exception to be thrown whenever the email address does not exist, for example. However, SmtpClient.Send does not throw an exception in this case, so I'd need to monitor the delivery failure replies and parse them, maybe. I know this is not a simple task, so I'd ask you experts some tips on how to handle the main issues with email sending. Thanks in advance!!

Somebody has got any ideas?

• Is there a way to use a dictionary or xml in the Application Settings?

  - by Shimmy

  I have to store a complex type in the application settings. I thought that storing it as XML would work best. The problem is I don't know how store XML. I prefer to store it as a managed XML rather than using just a string of raw XML having to parse it on each access. I managed to set the Type column of the setting to XDocument, but I was unable to set its value. Is there a way to use XDocument or XML in application settings? Update I found a way, simply by editing the .settings file with the xml editor. I changed it to a custom serializable dictionary, but I get the following error when I try to access the setting-property (I set it to a serialized representation of the default value). The property 'Setting' could not be created from it's default value. Error message: There is an error in XML document (1, 41). Any ideas will be appreciated.

• how to create english language dictionary application with python (django)?

  - by sintaloo

  Hi All, I would like to create an online dictionary application by using python (or with django). It will be similar to http://dictionary.reference.com/. My question is (1) Are there any existing open source python package or modules or application which implements this functionality that I can use or study from? (2) If the answer to the first question is NO. which algorithm should I follow to create such web application? Can I simply use the python built-in dictionary object for this job? so that the dictionary object's key will be the english word and the value will be the explanation. is this OK in term of performance? OR Do I have to create my own Tree Object to speed up the search? or any existing package which handles this job properly? Thank you very much.

• Retrieve Access Control List of Documents for Specific User on Google Docs?

  - by viatropos

  I have a large website at www.mydomain.com. There are 1000 new documents per month and 100 new users per week lets say. I need to be able to programmatically do the following: user goes to www.mydomain.com/documents user sees list of all documents they have access to (not ALL of the docs) I know you can retrieve an ACL for each document individually. But is there a way to retrieve an ACL for each "user", a list of all the documents they have access to, in one HTTP request? Something like this, but for Docs (and not just for document "owners"): Retrieving only calendars that a user owns. I'd love to know, because it seems like I'd have to parse 10,000 document "entry" tags, find the ACL, see if user is in ACL... That seems crazy. What am I missing? Thanks!

• loop in simplexml load file

  - by shantanuo

  I am using the following code to parse the XML data to MySQL table and it is working as expected. <?php $sxe = simplexml_load_file("$myfile"); foreach($sxe->AUTHAD as $sales) { $authad="insert into test.authad values ('".mysql_real_escape_string($sales->LOCALDATE)."','".mysql_real_escape_string($sales->LOCALTIME)."','".mysql_real_escape_string($sales->TLOGID)."','" ... ?> The problem is that when I get a new xml file with different format, I can not use the above insert into statement and have to change the parameters manually. For e.g. $authadv_new="insert into test.authad values ('".mysql_real_escape_string($sales->NEW1)."','".mysql_real_escape_string($sales->NEW2)."','".mysql_real_escape_string($sales->NEW3)."','" ... Is there any way to automate this? I mean the PHP code should be able to anticipate the parameters and generate the mysql_real_escape_string($sales-NEW1) to NEW10 values using a loop.

• Pass value to an include file in php.

  - by Muhammad Sajid

  Hi, How do you pass a parameter into an include file? I tried the following but it doesn't work. include "myfile.php?var=123"; and in myfile.php, I try to retrieve the parameter using $_GET["var"]. include "myfile.php?var=123"; will not work. PHP searches for a file with this exact name and does not parse the parameter for that I also did this: include "http://MyGreatSite.com/myfile.php?var=123";but it does not also work. Any hints? Thanks.

• Actual SQL statement after bind variables specified

  - by bioffe

  I am trying to log every SQL statement executed from my scripts. However I contemplate one problem I can not overcome. Is there a way to compute actual SQL statement after bind variables were specified. In SQLite I had to compute the statement to be executed manually, using code below: def __sql_to_str__(self, value,args): for p in args: if type(p) is IntType or p is None: value = value.replace("?", str(p) ,1) else: value = value.replace("?",'\'' + p + '\'',1) return value It seems CX_Oracle has cursor.parse() facilities. But I can't figure out how to trick CX_Oracle to compute my query before its execution.

• Can the LibreOffice LightProof grammar library be used externally?

  - by Phyxx

  LibreOffice 3.5 includes a grammar checker, called (or maybe based on) LightProof. From what I have read, LightProof seems to be a Python library that can be used to check for custom grammar rules. But I can not for the life of me find a project page for LightProof. The closest I got was http://cgit.freedesktop.org/libreoffice/lightproof/tree/, which seems to be the code for the LibreOffice extension, not LightProof itself. So is LightProof actually a library that can be implemented in other applications, or is it just a code word for a LibreOffice feature?

• Any way to find out which line break char(s) to use in Javascript?

  - by Irro

  I'm trying to parse some text into a textarea control and at the same time replace all with ordinary line break chars. I have been able to do it in windows by replacing with CR (it didn't work with CRLF strangely enough, it gave me linebreak + empty space) but I'm afraid that this code won't work in Unix/Mac because they use LF for line break. Is there any way to use the system default line break char in javascript? Something similar to Environment.NewLine in .Net (I wasn't able to write backslash in this editor but I use /r for CR and /n for LF, replace / with backslash)

• Recommended place for pre-translated Zend Framework resources

  - by Exception e

  Since zf 1.10 Zend Framework ships with pre-translated validation messages. They are outside the library path. The manual illustrates how to load these in your bootstrap. $translator = new Zend_Translate( 'array', '/resources/languages', $language, array('scan' => Zend_Locale::LOCALE_DIRECTORY) ); Zend_Validate_Abstract::setDefaultTranslator($translator); I am inclined to think that these resources are specific to the zf-version; validators could change over time. If i copy the resources to my application tree I need to perform additional maintenance each time I upgrade to a newer version. What is best practice? Is there a ZF convention already?

• Get name and value from the input tag

  - by DroidIn.net

  Before you say "oh no, not again" here I'm stating my case. I'm parsing part of HTML output and the only thing I'm interested in is name and value attributes of each <input/ tag. HTML is actually HTML fragment, may not be well-formed. I don't have DOM or HTML parser and I don't try to parse nested elements anyway. The problem is that I don't know the order or number of attributes so it could be <input name="foo" value="boo"/> or <input type="hidden" name=foo> or <input id=blah value='boo' src="image.png" name="foo" type="img"/>. Is there a single regular expression that would get me values of name and value attribute in predictable order? I wouldn't have asked the question if I could assume that name attribute always precedes value but unfortunately this is not the case

• Create an Action<T> to "set" a property, when I am provided with the LINQ Expression for the "get"

  - by Alex

  I'd like to be able to generate a compiled expression to set a property, given the lambda expression that provides the "get" method for a property. Here's what I'm looking for: public Action<int> CreateSetter<T>(Expression<Func<T, int>> getter) { // returns a compiled action using the details of the getter expression tree, or null // if the write property is not defined. } I'm still trying to understand the various types of Expression classes, so if you can point me in the right direction that would be great.

• Is there a good (standalone) PHPDoc parser class or function in PHP?

  - by Kris

  Hi folks, I'm looking for some method of converting a PHP Docblock (as used for generating documentation by tools like Doxygen) into a structure I can inspect in PHP. For example, I want to parse the following lines: /** * Multiply two values * @CHECKME * * @author someone * @created eons ago * * @param integer $x * @param integer $x * * @return integer */ function multiply($x, $y) { return $x * $y; } Into something similar to: array( 'author' = 'someone' ,'created' = 'eons ago' ,'param' = array( 'integer $x' ,'integer $y' ) ,'_flags' = array( '@CHECKME' ) ); I explicitly cannot use PEAR or any such library, it has to be relatively standalone. Any given solution that is better than using a bunch of regexes after stripping away comment outline would be awesome.

• C# mysql one return last_insert_id

  - by Bernhard

  I am trying to create a method in which I can exequte mysql UPDATE, DELETE or INSERT query. The method must work when with an INSERT I ask or do not ask the last_insert_id(). Below is the code that I have at the moment: public int executeUID(MySqlCommand msCommand) { try { this.Open(); msCommand.Connection = this.msCon; return int.Parse(msCommand.ExecuteScalar().ToString()); } catch (MySqlException ex) { throw ex; } finally { this.Close(); } } The problem with this is is that when I use an insert query that returns a last_insert_id() the method works greatly. But when the query doesn't return an last_insert_id() the method malfunctions. How can I get this method to work?

• jQuery selector - style values

  - by kender

  I got a series of divs like this: <div class="message" style="padding-left: 0px;">...</div> <div class="message" style="padding-left: 20px;">...</div> <div class="message" style="padding-left: 20px;">...</div> <div class="message" style="padding-left: 40px;">...</div> <div class="message" style="padding-left: 20px;">...</div> And I would like to make a selector that would get me the divs with padding greater then 20px. Would it be possible with just using jquery? Or I should modify my html tree and add some attribute that would distinguish those elemenents with high padding value?

• python [lxml] - cleaning out html tags

  - by sadhu_

  from lxml.html.clean import clean_html, Cleaner def clean(text): try: cleaner = Cleaner(scripts=True, embedded=True, meta=True, page_structure=True, links=True, style=True, remove_tags = ['a', 'li', 'td']) print (len(cleaner.clean_html(text))- len(text)) return cleaner.clean_html(text) except: print 'Error in clean_html' print sys.exc_info() return text I put together the above (ugly) code as my initial forays into python land. I'm trying to use lxml cleaner to clean out a couple of html pages, so in the end i am just left with the text and nothing else - but try as i might, the above doesnt appear to work as such, i'm still left with a substial amount of markup (and it doesnt appear to be broken html), and particularly links, which aren't getting removed, despite the args i use in remove_tags and links=True any idea whats going on, perhaps im barking up the wrong tree with lxml ? i thought this was the way to go with html parsing in python?
