  • Is it possible to slice off the end of a URL with XSLT 1.0?

    - by Eric
    Title says it all really. Using only XSLT 1.0's string functions, how would I go about slicing off the end of a url? So from http://stackoverflow.com/questions/2981175/is-it-possible-to-slice-the-end-of-a-url-with-xslt-1-0 I would like to extract is-it-possible-to-slice-the-end-of-a-url-with-xslt-1-0 Is this possible?

  • Automated obscuring of PDF content

    - by Manabenz
    Hello I'm looking for a tool which will allow me to automate the task of obscuring a certain section of content contained within a PDF. The PDF content is essentially one big image which contains some sensitive information, and it is this information we need to ensure is not readable. Any tips for where I should start looking for such a solution? Many thanks M

  • Manipulate data for scaling

    - by user1487000
    I have this data: Game 1: 7.0/10.0, Reviewed: 1000 times Game 2: 7.5/10.0, Reviewed: 3000 times Game 3: 8.9/10.0, Reviewed: 140,000 times Game 4: 10.0/10.0 Reviewed: 5 times . . . I want to manipulate this data in a way to make each rating reflective of how many times it has been reviewed. For example Game 3 should have a little heavier weight than than Game 4, since it has been reviewed way more. And Game 2's 7 should be weighted more than Game 1's 7. Is there a proper function to do this scaling? In such a way that ScaledGameRating = OldGameRating * (some exponential function?)

  • Is the “jQuery programming style” a kind of Reactive programming?

    - by Peter Krauss
    jQuery is a Javascript library and framework, but when we are programming with jQuery into DOM problems/solutions, we can practice a style quite different of programming... We can read about jQuery at Wikipedia, The set of jQuery core features — DOM element selections, traversal and manipulation —, enabled by its selector engine (...), created a new "programming style", fusing algorithms and DOM-data-structures This question is similar to the "subquestion-3" of this question but not so generic. The focus here is about this new kind of "programming style"... So, the question: Is the "jQuery programming style in DOM context" a new paradign? Or it is more one example of reactive programming (not "cell-oriented" but "DOM-node oriented") or another one? We have no "standard taxonomy of paradigms", so, please, in your answer, indicate also your "best choice for Wikipedia Paradign". Example: if you understand that "jQuery programming DOM" is like "awk filtering data", your choice can be event-driven.

  • Are there efforts to build a collaboratively edited HTML/JS/DOM reference?

    - by Pekka
    W3Schools has a reputation of being incomplete, sometimes incorrect, and ridden with advertising; still, when looking to look up some things or link to documentation when answering a SO question, it still is the only handy cross-browser resource. There are other resources like the Mozilla Developer Network that is doing an increasingly great job documenting JavaScript, and the legendary and great Quirksmode. But they, as brilliant as they are, cover only parts of the areas I am talking about, and provide no community editing and quality control options. Is anybody aware of efforts to create a collaboratively edited, cross-browser HTML/CSS/JavaScript/DOM encyclopedia? If you will, I'm thinking of a challenger to W3Schools like SO was to Experts Exchange. (I thought this more suitable on Programmers than on SO proper - please correct me if I'm wrong.)

  • Java single Array best choice for accessing pixels for manipulation?

    - by Petrol
    I am just watching this tutorial https://www.youtube.com/watch?v=HwUnMy_pR6A and the guy (who seems to be pretty competent) is using a single array to store and access the pixels of his to-be-rendered image. I was wondering if this really is the best way to do this. The alternative of Multi-Array does have one pointer more, but Arrays do have an O(1) for accessing each index and calculating the index in a single array seems to take one addition and one multiplication operation per pixel. And if Multi-Arrays really are bad, can't you use something with Hashing to avoid those addition and multiplication operations? EDIT: here is his code... public class Screen { private int width, height; public int[] pixels; public Screen(int width, int height) { this.width = width; this.height = height; // creating array the size of one index/int for every pixel // single array has better performance than multi-array pixels = new int[width * height]; } public void render() { for (int y = 0; y < height; y++) { for (int x = 0; x < width; x++) { pixels[x + y * width] = 0xff00ff; } } } }

  • Prototype JS swallows errors in dom:loaded, and ajax callbacks?

    - by WishCow
    I can't figure out why prototype suppressess the error messages in the dom:loaded event, and in AJAX handlers. Given the following piece of HTML: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Conforming XHTML 1.1 Template</title> <script type="text/javascript" src="prototype.js"></script> <script type="text/javascript"> document.observe('dom:loaded', function() { console.log('domready'); console.log(idontexist); }); </script> </head> <body> </body> </html> The domready event fires, I see the log in the console, but there is no indication of any errors whatsoever. If you move the console.log(idontexist); line out of the handler, you get the idontexist is not defined error in the console. I find it a little weird, that in other event handlers, like 'click', you get the error message, it seems that it's only the dom:loaded that has this problem. The same goes for AJAX handlers: new Ajax.Request('/', { method: 'get', onComplete: function(r) { console.log('xhr complete'); alert(youwontseeme); } }); You won't see any errors. This is with prototype.js 1.6.1, and I can't find any indication of this behavior in the docs, nor a way to enable error reporting in these handlers. I have tried stepping through the code with FireBug's debugger, and it seems to jump to a function on line 53 named K, when it encounters the missing variable in the dom:loaded handler: K: function(x) { return x } But how? Why? When? I can't see any try/catch block there, how does the program flow end up there? I know that I can make the errors visible by packing my dom:ready handler(s) in try/catch blocks, but that's not a very comfortable option. Same goes for registering a global onException handler for the AJAX calls. Why does it even suppress the errors? Did someone encounter this before?

  • Can I get the matched DOM string with PHP and DOMDocument?

    - by alex
    I've got my HTML inside of $html. dom = new DOMDocument(); $dom->loadHTML($html); $xpath = new DOMXPath($dom); $tags = $xpath->query('//div[@id="header"]'); foreach($tags as $tag) { var_dump($tag->nodeValue); // the innerHTML of that element var_dump($tag); // object(DOMElement)#3 (0) { } } Is there a way to get that node, or remove it? Basically, I'm parsing an existing website and need to remove elements from it. What method do I call to do that? Thanks

  • Introducing jLight &ndash; Talking to the DOM using Silverlight and jQuery.

    - by Timmy Kokke
    Introduction With the recent news about Silverlight on the Windows Phone and all the great Out-Of-Browser features in the upcoming Silverlight 4 you almost forget Silverlight is a browser plugin. It most often runs in a web browser and often as a control. In many cases you need to communicate with the browser to get information about textboxes, events or details about the browser itself. To do this you can use JavaScript from Silverlight. Although Silverlight works the same on every browser, JavaScript does not and it won’t be long before problems arise. To overcome differences in browser I like to use jQuery. The only downside of doing this is that there’s a lot more code needed that you would normally use when you write jQuery in JavaScript. Lately, I had to catch changes is the browser scrollbar and act to the new position. I also had to move the scrollbar when the user dragged around in the Silverlight application. With jQuery it was peanuts to get and set the right attributes, but I found that I had to write a lot of code on Silverlight side.  With a few refactoring I had a separated out the plumbing into a new class and could call only a few methods on that to get the same thing done. The idea for jLight was born. jLight vs. jQuery The main purpose of jLight is to take the ease of use of jQuery and bring it into Silverlight for handling DOM interaction. For example, to change the text color of a DIV to red, in jQuery you would write: jQuery("div").css("color","red"); In jLight the same thing looks like so: jQuery.Select("div").Css("color","red");   Another example. To change the offset in of the last SPAN you could write this in jQuery : jQuery("span:last").offset({left : 10, top : 100});   In jLight this would do the same: jQuery.Select("span:last").Offset(new {left = 10, top = 100 });   Callbacks Nothing too special so far. To get the same thing done using the “normal” HtmlPage.Window.Eval, it wouldn’t require too much effort. But to wire up a handler for events from the browser it’s a whole different story. Normally you need to register ScriptMembers, ScriptableTypes or write some code in JavaScript. jLight takes care of the plumbing and provide you with an simple interface in the same way jQuery would. If you would like to handle the scroll event of the BODY of your html page, you’ll have to bind the event using jQuery and have a function call back to a registered function in Silverlight. In the example below I assume there’s a method “SomeMethod” and it is registered as a ScriptableObject as “RegisteredFromSilverlight” from Silverlight.   jQuery("body:first").scroll(function() { var sl = document.getElementbyId("SilverlightControl"); sl.content.RegisteredFromSilverlight.SomeMethod($(this)); });       Using jLight  in Silverlight the code would be even simpler. The registration of RegisteredFromSilverlight  as ScriptableObject can be omitted.  Besides that, you don’t have to write any JavaScript or evaluate strings with JavaScript.   jQuery.Select("body:first").scroll(SomeMethod);   Lambdas Using a lambda in Silverlight can make it even simpler.  Each is the jQuery equivalent of foreach in C#. It calls a function for every element found by jQuery. In this example all INPUT elements of the text type are selected. The FromObject method is used to create a jQueryObject from an object containing a ScriptObject. The Val method from jQuery is used to get the value of the INPUT elements.   jQuery.Select("input:text").Each((element, index) => { textBox1.Text += jQueryObject.FromObject(element).Val(); return null; });   Ajax One thing jQuery is often used for is making Ajax calls. Making calls to services to external services can be done from Silverlight, but as easy as using jQuery. As an example I would like to show how jLight does this. Below is the entire code behind. It searches my name on twitter and shows the result. This example can be found in the source of the project. The GetJson method passes a Silverlight JsonValue to a callback. This callback instantiates Twit objects and adds them to a ListBox called TwitList.   public partial class DemoPage2 : UserControl { public DemoPage2() { InitializeComponent(); jQuery.Load(); }   private void CallButton_Click(object sender, RoutedEventArgs e) { jQuery.GetJson("http://search.twitter.com/search.json?lang=en&q=sorskoot", Done); }   private void Done(JsonValue arg) { var tweets = new List<Twit>(); foreach (JsonObject result in arg["results"]) { tweets.Add(new Twit() { Text = (string)result["text"], Image = (string)result["profile_image_url"], User = (string)result["from_user"] } ); } TwitList.ItemsSource = tweets; } }   public class Twit { public string User { get; set; } public string Image { get; set; } public string Text { get; set; } }   Conclusion Although jLight is still in development it can be used already.There isn’t much documentation yet, but if you know jQuery jLight isn’t very hard to use.  If you would like to try it, please let me know what you think and report any problems you run in to. jLight can be found at:   http://jlight.codeplex.com

  • Is there a JQuery DOM manipulator/CSS selector equivalent class in PHP?

    - by DKinzer
    I know that I can use DOMDocument and DOMXPath to manipulate XML files. But, I really love JQuery, and it would be great if there was something more like JQuery in the PHP world that I could use for sever side DOM manipulation. NOTE: I'm only interested here in how JQuery Selects and Manipulates the DOM, not all the other parts of JQuerry (I guess you can say just the Pop and the Sizzle parts).

  • Is it possible to return the "highlighted" (like Firebug) css selector or dom id with jquery?

    - by Jonathan
    Hi Folks, When you click the "Click an element on the page to inspect" arrow with FireBug, it puts a Blue Border around the target element, and also returns the DOM Id. I am building an application and that feature would be awesome to add. Be able to hover over elements and highlight the target, upon clicking return the DOM Id or CSS selector to the application. Is there a jquery plugin that does this magic? Some other smart way? Thanks!, Jonathan

  • What is the best way to do Bit Field manipulation in Python?

    - by ZebZiggle
    I'm reading some MPEG Transport Stream protocol over UDP and it has some funky bitfields in it (length 13 for example). I'm using the "struct" library to do the broad unpacking, but is there a simple way to say "Grab the next 13 bits" rather than have to hand-tweak the bit manipulation? I'd like something like the way C does bit fields (without having to revert to C). Suggestions?

  • Is there a web tool framework for building a video editing/manipulation widget other than custom Fla

    - by Brandon
    I am looking to build a widget for a site which allows users to tag images from individual frames of a video file but would prefer not to have to build a custom Flash tool. Is there an existing free library or framework which simplifies things like this in a webapplication setting? Features would also involve basic video playback functionality as well as time-driven meta-data and the ability to extract images from individual video frames. Are there existing open-source web-based tools for video manipulation other than building your own custom Flash app?

  • Is XMLReader a SAX parser, a DOM parser, or neither?

    - by Renesis
    I am testing various methods to read (possibly large, and very often) XML configuration files in PHP. No writing is ever needed. I have two successful implementations, one using SimpleXML (which I know is a DOM parser) and one using XMLReader. I know that a DOM reader must read the whole tree and therefore uses more memory. My tests reflect that. I also know that A SAX parser is an "event-based" parser that uses less memory because it reads each node from the stream without checking what is next. XMLReader also reads from a stream with the cursor providing data about the node it is currently at. So, it definitely sounds like XMLReader (http://us2.php.net/xmlreader) is not a DOM parser, but my question is, is it a SAX parser, or something else? It seems like XMLReader behaves the way a SAX parser does but does not throw the events themselves (in other words, can you construct a SAX parser with XMLReader?) If it is something else, does the classification it's in have a name?

  • Getting an non-object error in my php script

    - by Disowned
    Hey I was trying to call a script to made some changes to an html file, however when I run the script it tells me that it's making a call to a non-object. Obviously I did something wrong, but what? Here's the script. /*Dom controllers*/ $dom = new DOMDocument(); $dom->loadHTML('index.html'); $id = $dom->getElementById('contact_us'); $p = $dom->appendChild(new DOMElement('p')); $op = $dom->getElementsByTagName('p'); /* Dem POST vars used by dat Ajax mah ziggen, yeah boi*/ if (isset($_POST['Home']) && isset($_POST['About']) && isset($_POST['Contact']) && isset($_POST['sexyText'])){ $home = $_POST['Home']; $about = $_POST['About']; $contact = $_POST['Contact']; $text = $_POST['sexyText']; trim($home); trim($about); trim($contact); trim($text); } function post(){ global $dom, $id, $home, $about, $contact, $text, $textp, $p, $op; $textp = $dom->createTextNode($text); $p->appendChild($textp); $id->replaceChild($p, $op); $dom->saveHTMLFile('index.html'); } post(); echo 1; ?> The error happens at the replaceChild function.

  • Does anyone use Fortify 360 with Classic ASP? a Header Manipulation vulnerability story

    - by j_green71
    Good morning, everyone. I'm on a short-term contracting gig, trying to patch some vulnerabilities in their legacy code. The application I'm working on is a combination of Classic ASP(VBScript) and .Net 2.0 (C#). One of the tools they have purchased is Fortify 360. Let's say that this is a current classic ASP page in the application: <%@ Language=VBScript %> <% Dim var var = Request.QueryString("var") ' do stuff Response.Redirect "nextpage.asp?var=" & var %> I know, I know, short and very dangerous. So we wrote some (en/de)coders and validation/verification routines: <%@ Language=VBScript %> <% Dim var var = Decode(Request.QueryString("var")) ' do stuff if isValid(var) then Response.Redirect "nextpage.asp?var=" & Encode(var) else 'throw error page end if %> And still Fortify flags this as vulnerable to Header Manipulation. How or what exactly is Fortify looking for? The reason I suspect that Fortify is looking for specific key words is that on the .Net side of things, I can include the Microsoft AntiXss assembly and call functions such as GetSafeHtmlFragment and UrlEncode and Fortify is happy. Any advice?

  • How do I access the popup page DOM from bg page in Chrome extension?

    - by Fletcher Moore
    In Google Chrome's extension developer section, it says The HTML pages inside an extension have complete access to each other's DOMs, and they can invoke functions on each other. ... The popup's contents are a web page defined by an HTML file (popup.html). The popup doesn't need to duplicate code that's in the background page (background.html) because the popup can invoke functions on the background page I've loaded and tested jQuery, and can access DOM elements in background.html with jQuery, but I cannot figure out how to get access to DOM elements in popup.html from background.html.
