  - by Ummar

  Hi I am developing an application in Silverlight 3.0, I want to make a generic parser of XML in it, as on every call to webservice I am receiving a different XML, I want to make it generic so that I receive an XML in native datastructure of C#? Please help me out? like I am getting XML like this one time <test> <node1></node1> <node2></node2> </test> and other time <mytest> <application name="XYZ">My Application</application> <application name="ABC">My Application</application> </mytest> I want the generic parser, e.g. it makes some tree structure of whole XML

• Printing UTF-16 strings in JSP is outputted as HTML encoding (&#xxxx)

  - by Ori Osherov

  Hello, When I try to print a UTF-16 string in JSP, specifically Hebrew, it ends up showing up as HTML encoding (&#xxxx). This problem occurs because I print an array of variables into the web page and then parse them. The variables are all UTF-16 strings, but once the servlet prints the variables, it becomes translated to HTML encoding. Is there any way to get rid of the encoding? Thanks in advance Edit for a bit more background: The JSP that I'm printing is not the entirety of the page. It's used in a manner I don't quite understand by a server app which prints the JSPs output into its built in page. As a result, I can't, for instance, use a tag because the will have already been placed somewhere else. This isn't a frame or anything like that. It's just redirected output.

• One regular expression to match parts in various positions

  - by richsage

  Hi all, I'm trying to parse a DSN (from a Symfony application) using regular expressions, in order to link with a secondary application, but using the same database. The DSN I currently have is: mysql:dbname=my_db_name;host=localhost with a regex of: /^(\w+):(dbname=(\w+))?;?(host=(\w+))?/ (using preg_match()). This matches OK, but fails in my test environment because the DSN elements are switched around, thus: mysql:host=localhost;dbname=my_testdb_name I could just switch them round, yes :-) but I'm sure that extraction of the host and dbname parts from both DSNs is possible with a single regular expression, and I'd like to be able to enhance my knowledge at the same time ;-) Is there a way I can do this?

• parsing xml attribute value

  - by vbNewbie

  I have been parsing xml content using the xmlreader and cannot use the xml document but so far it works getting all elementcontent except for the attribute contents. I need to parse the link below found in the following entry; <title>XXXX UUUUUU posted a</title> <category term="NotePosted" label="Note Posted"/> <link rel="alternate" type="html" href="http://www.dfsddsfdsf.com/profile.php?id=sdfdfsfdsdfddfsfd&amp;v=wall&amp;story_dbid=dssdfasdfdasfdsafafafa"/> <source>......... <source> I need the href tag in the link attribute but it keeps coming back null. While ureader.Read If ureader.HasAttributes Then fId = ureader.GetAttribute("href") If fId.Contains("?v=wall&amp") Then fIdList.Add(fId) Exit While End If If String.IsNullOrEmpty(fId) Then fId = "NOTHING" End If End If End While

• Calling HttpRequest::getRawRequestMessage() without send()

  - by danielgrad

  I am trying to call getRawRequestMessage() to get the raw HTTP content of the request described by a HttpRequest object, but I notice it always returns an empty string if I don't call send() first. Which kind of defeats my purpose (I want to send the data through other means than the HttpRequest's own send() method). Is there any other way to convert a HttpRequest object to it's raw string equivalent? To give more context: I'm working with a complex class that builds a HttpRequest object and sends requests through it and I want to add a new mode to the class that will work through raw sockets instead. The request is already built in the HttpRequest object and I would like to not have to parse the object manually to generate the HTTP message.

• Asking for input without stopping the script in python.

  - by ImTooStupidForThis

  I am (trying) to make a simple IRC client in python (as kind of a project while I learn the language). I have a loop that I use to receive and parse what the IRC server sends me, but if I use raw_input to input stuff, it stops the loop dead in its tracks until I input something (obviously). How can I input something without the loop stopping? Thanks in advance. (I don´t think I need to post the code, I just want to input something without the while 1 loop stopping.)

• Approach to data wrapping

  - by Mikhail

  I'm developing in PHP and MySQL. The information about the currently logged in user is stored in many different tables. The information that I need on each page, I preload. However if something is needed from a rarely accessed table - then I do $newdata = $db->Query('SELECT * FROM rare_table WHERE user_id='.$user->id); I would like to simplify the above to a point where I don't have to specify that the query should be limited to this particular user. An ideal function call would be: $newdata = $user->Query('SELECT * FROM rare_table'); Obviously I'd have to parse the SQL and add a WHERE clause. Or add to the already existing clause. Questions: are there tools to do this? How can I develop this? Is this even a good idea?

• Create new Array of parameter type

  - by pimvdb

  I'm trying to create a function to parse out all values in a multidimensional Array with all but one dimension given. The details are not relevant, but for this function I need to return an one-dimensional Array containing values of the same type the original multidimensional Array has. To pass any Array with any dimension to my function, I declared the type of this parameter as Array. However, how would I create a new Array of that specific type (e.g. Integer)? Currently I have the following code: Function GetRow(ByVal arr As Array) As Array Dim result As (...) 'This should be Integer() if arr contains Integers, etc. Return result End Function How do I declare the type of result to make it having the same type of values as arr? New Array is not possible as it is declared MustInherit. Thanks a lot.

• Using cProfile results with KCacheGrind

  - by Adam Luchjenbroers

  I'm using cProfile to profile my Python program. Based upon this talk I was under the impression that KCacheGrind could parse and display the output from cProfile. However, when I go to import the file, KCacheGrind just displays an 'Unknown File Format' error in the status bar and sits there displaying nothing. Is there something special I need to do before my profiling stats are compatible with KCacheGrind? ... if profile: import cProfile profileFileName = 'Profiles/pythonray_' + time.strftime('%Y%m%d_%H%M%S') + '.profile' profile = cProfile.Profile() profile.run('pilImage = camera.render(scene, samplePattern)') profile.dump_stats(profileFileName) profile.print_stats() else: pilImage = camera.render(scene, samplePattern) ...

• Convert integer to equivalent number of blank spaces.

  - by mike

  I was wondering what the easiest way is to convert an integer to the equivalent number of blank spaces. I need it for the spaces between nodes when printing a binary search tree. I tried this `int position = printNode.getPosition(); String formatter = "%1"+position+"s%2$s\n"; System.out.format(formatter, "", node.element);` But I am getting almost 3 times as many spaces compared to the int value of position. I'm not really sure if I am formatting the string right either. Any suggestions would be great! If it makes it clearer, say position = 6; I want 6 blank spaces printed before my node element.

• How to extract img src, title and alt from html using php?

  - by Sam

  I would like to create a page where all images which reside on my website are listed with title and alternative representation. I already wrote me a little program to find and load all html files, but now I am stuck at how to extract src, title and alt from the html < img src="/image/fluffybunny.jpg" title="Harvey the bunny" alt="a cute little fluffy bunny"/ I guess this should be done with some regex, but since the order of the tags may vary, and I need all of them, I don't really know how to parse this in an elegant way (I could do it the hard char by char way, but thats painful).

• Parsing String to TreeNode

  - by Krusu70

  Anyone have a good algorithm how to parse a String to TreeNode in Java? Let's say we have a string s which says how to build a TreeNode. A(B,C) means that A is the name (String) of TreeNode, B is child of A (Treenode), C is sibling of A (TreeNode). So if I call function with string A(B(D,E(F,G)),C) (just a example), then I get a TreeNode equals to: level A (String: name), B - Child (TreeNode), C - Sibling (TreeNode) level B (String: name), D - Child of B (TreeNode), E - Sibling of B (TreeNode) level E (String: name), F - Child of E (TreeNode), G - Sibling of E (TreeNode) The name may not be 1 letter, it could be like real name (many letters).

• How do you log php errors with CakePHP when debug is 0?

  - by Justin

  I would like to log PHP errors on a CakePHP site that has debug = 0. However, even if I turn on the error log, like this: error_reporting = E_ALL & ~E_NOTICE & ~E_DEPRECATED log_errors = On it doesn't log errors. The problem is that even for a parse error that should cause the CakePHP environment to not load completely (I think), it still blocks the error from being logged. If I set debug to 3, it logs to the file without issue. I am using CakePHP 1.2. I know this is apparently made easier in 1.3, but I'm not ready to upgrade.

• How to decode U.P.S. Information from UPS MaxiCode Barcode?

  - by user46482

  I recently purchased a 2D Barcode reader. When scanning a U.P.S. barcode, I get about half of the information I want, and about half of it looks to be encrypted in some way. I have heard there is a UPS DLL. Example - Everything in bold seems to be encrypted, while the non-bold text contains valuable, legitimate data. [)01961163522424800031Z50978063UPSN12312307G:%"6*AH537&M9&QXP2E:)16(E&539R'64O In other words, this text seems OK - and I can parse the information [)01961163522424800031Z50978063UPSN123123 ... While, this data seems to be encrypted ... 07G:%"6*AH537&M9&QXP2E:)16(E&539R'64O Any Ideas???

• Can I pass events like key strokes to another control in Silverlight?

  - by herzmeister der welten

  Can I pass events like key strokes to another control in Silverlight? Imagine I'm in a custom control that contains a Textbox and a Treeview. I'm listening to a Key event for the TextBox. When the user pushes the Arrow Up or Arrow Down key, I want the Treeview to behave as if it's itself who received that event, i.e. it should move the current selection up or down. The user shouldn't lose focus on the TextBox though so that they can continue typing. Is this possible? I don't want to set the selection manually on the Treeview because it has no easy MoveSelectionUp() or MoveSelectionDown() method, so I would have to duplicate that functionality which is not so trivial especially when the tree is databound and loads nodes on demand.

• iOS - Open an app with a URL Scheme from Chrome

  - by Brett

  I've read many many blogs and examples of how to open an app from an URL scheme (for example, this blog), and it seems to work great when I call my app from mobile safari. For instance, when I call testapp://some.data.here in mobile safari, it opens my testapp and I can parse out the some.data.here. However, when I call testapp://some.data.here in iOS-Chrome, it just googles the term instead of calling the app. Is there a way to have iOS Chrome recognize the URL as a registered app the way mobile safari does? When I google this topic, I see a lot of comments on how to open a url in chrome from an app, but not the other way around. Has anyone encountered this? Thanks!

• Setting many key/value pairs

  - by Andrew

  Hi, I'm working on a rake task which imports from a JSON feed into an ActiveRecord called Person. Person has quite a few attributes and rather than write lines of code for setting each attribute I'm trying different methods. The closest I've got is shown below. This works nicely as far as outputing to screen but when I check the values have actually been set on the ActiveRecord itself it's always nil. So it looks like I can't use .to_sym to solve my problem? Any suggestions? I should also mention that I'm just starting out with Ruby, have been doing quite a bit of Objective-c and now need to embrace the Interwebs :) http = Net::HTTP.new(url.host, url.port) http.read_timeout = 30 json = http.get(url.to_s).body parsed = JSON.parse(json) if parsed.has_key? 'code' updatePerson = Person.find_or_initialize_by_code(parsed['code']) puts updatePerson.code parsed.each do |key, value| puts "#{key} is #{value}" symkey = key.to_sym updatePerson[:symkey] = value.to_s updatePerson.save puts "#{key}....." # shows the current key puts updatePerson[:symkey] # shows the correct value puts updatePerson.first_name # a sample key, it's returning nil end

• How to get Anchor text using DomDocument?

  - by Click Upvote

  Say I have this html: <a href="http://example.com">Test</a> I parse it using dom document with this code: $dom = new DomDocument(); @$dom->loadHTML($html); $urls = $dom->getElementsByTagName('a'); And then I run this code: foreach ($urls as $url) { //echo "<br> {$url->getAttribute('href')} , {$url->getAttribute('title')}"; foreach ($url->attributes as $a) { echo "<br>$a->name is $a->value"; } echo "<hr><br>"; } When I do this, I only see 'href' as an attribute of the url, there's no way to get the 'anchor text' (in the above case 'Test'). How can I get the anchor text of the link?

• Best practice when working with web services that return objects?

  - by Raj

  Hello, I'm currently working with web services that return objects such as a list of files e.g. File array. I wanted to know whether its best practice to bind this type of object directly to my front end code for example a repeater/listview or whether to first parse it into my own list of "file class" e.g. customFiles[] If the web service changes then it will break my front end code, however if I create my own CustomFile class, then i would only need to change my code in one place to fix the issue, but it just seems like a lot of extra work to create the same classes from a web service, i wanted to know what is the best practice for this type of work. thanks Raj.

• Python: Pickling highly-recursive objects without using `setrecursionlimit`

  - by cool-RR

  I've been getting RuntimeError: maximum recursion depth exceeded when trying to pickle a highly-recursive tree object. Much like this asker here. He solved his problem by setting the recursion limit higher with sys.setrecursionlimit. But I don't want to do that: I think that's more of a workaround than a solution. Because I want to be able to pickle my trees even if they have 10,000 nodes in them. (It currently fails at around 200.) (Also, every platform's true recursion limit is different, and I would really like to avoid opening this can of worms.) Is there any way to solve this at the fundamental level? If only the pickle module would pickle using a loop instead of recursion, I wouldn't have had this problem. Maybe someone has an idea how I can cause something like this to happen, without rewriting the pickle module? Any other idea how I can solve this problem will be appreciated.

• How can I programmatically copy all of the style attributes from one DOM element to another

  - by stu

  I have a page with two frames, and I need to (via javascript) copy an element and all of its nested elements (it's a ul/li tree) and most importantly it's style from one frame to the other. I get all the content via assigning innerhtml, and I am able to position the new element in the second frame with dest.style.left and dest.style.top and it works. But I'm trying to get all the style information and nothing's happening. I'm using getComputedStyle to get the final style for each source element as I loop through each node then and assigning them to the same position in the destination nodelist and nothing happens to visually change the style. What am I missing?
