  • C#: split a string into runs of characters, numbers and delimited strings and process it

    - by nrkn
    OK my regex is a bit rusty and I've been struggling with this particular problem... I need to split and process a string containing any number of the following, in any order: Chars (lowercase letters only) Quote delimited strings Ints The strings are pretty weird (I don't have control over them). When there's more than one number in a row in the string they're seperated by a comma. They need to be processed in the same order that they appeared in the original string. For example, a string might look like: abc20a"Hi""OK"100,20b With this particular string the resulting call stack would look a bit like: ProcessLetters( new[] { 'a', 'b', 'c' } ); ProcessInts( 20 ); ProcessLetters( 'a' ); ProcessStrings( new[] { "Hi", "OK" } ); ProcessInts( new[] { 100, 20 } ); ProcessLetters( 'b' ); What I could do is treat it a bit like CSV, where you build tokens by processing the characters one at a time, but I think it could be more easily done with a regex?

  • how to write regular expression to validate a string using regex in C#

    - by Charu
    I need to validate a user input based on condition. i wrote a regular expression to do so, but it's failing not sure why. Can somebody point where i am making mistake? Regex AccuracyCodeHexRegex = new Regex(@"^[PTQA]((0|8)[01234567]){2}$"); This is what i am trying to validate(If the string is a subset of these strings then it is valid): Phh, Thh, Qhh, Ahh where 'h' is a hex digit in the set {00, 80, 01, 81, 02, 82, 03, 83, 04, 84, 05, 85, 06, 86, 07, 87} Ex: P00 is valid P20 is not valid

  • PHP Dom problem, how to insert html code in a particular div

    - by sala_7
    I am trying to replace the html code inside the div 'resultsContainer' with the html of $response. The result of my unsuccessful code is that the contents of 'resultsContainer' remain and the html of $response shows up on screen as text rather than being parsed as html. Finally, I would like to inject the content of $response inside 'resultContainer' without having to create any new div, I need this: <div id='resultsContainer'>Html inside $response here...</div> and NOT THIS: <div id='resultsContainer'><div>Html inside $response here...</div></div> // Set Config libxml_use_internal_errors(true); $doc = new DomDocument(); $doc->strictErrorChecking = false; $doc->validateOnParse = true; // load the html page $app = file_get_contents('index.php'); $doc->loadHTML($app); // get the dynamic content $response = file_get_contents('search.php'.$query); $response = utf8_decode($response); // add dynamic content to corresponding div $node = $doc->createElement('div', $response); $doc->getElementById('resultsContainer')->appendChild($node); // echo html snapshot echo $doc->saveHTML();

  • An html input box isn't being displayed, Firebug says it has style="display: none" but I haven't don

    - by Ankur
    I have placed a form on a page which looks like this: <form id="editClassList" name="editClassList" method="get" action="EditClassList"> <label> <input name="class-to-add" id="class-to-add" size="42" type="text"> </label> <label> <input name="save-class-btn" id="save-class-btn" value="Save Class(es)" type="submit"> </label> </form> But when it get's rendered by a browser it comes out like this: <form id="editClassList" name="editClassList" method="get" action="EditClassList"> <label> <input style="display: none;" name="class-to-add" id="class-to-add" size="42" type="text"> </label> <label> <input name="save-class-btn" id="save-class-btn" value="Save Class(es)" type="submit"> </label> </form> For some reason style="display: none;" is being added, and I cann't understand why. This results in the text box not displaying.

  • What is the most semantic way to display a street address in HTML?

    - by tomk
    I have an address that is going to be displayed on a webpage, but it is not the address for the author of the page. How should this be coded to be semantic given the w3c recommendation of: The ADDRESS element may be used by authors to supply contact information for a document or a major part of a document such as a form. This element often appears at the beginning or end of a document.

  • (HTML) PNG on top of another PNG - possible to eliminate full transparency?

    - by MHTri
    I'd like to put a logo png onto of another coloured png. They both have transparent backgrounds. When I try this the images blend together. Curiously, in Photoshop the logo retains its opaque-ness - I put colours on the layers underneath it, another image, etc etc, the logo is still opaque. I'd like to do it this way so I can rotate the background images. How do I fix this? [edit]I've cooked up an example image: http://i.imgur.com/XtoGn.png The left is what I want to happen, the right is what happens on all browsers (I know the background isn't transparent but bear with me - they're both transparent pngs, with the background having a gradient layer mask). I've put the images like this <div> <img id="backgroundImg" style="position: absolute; top: 0;" src="/Images/background.png" /> <img id="logoImg" src="/Images/logo.png" /> </div> I'm not entirely sure what blending mode I'm using in PS.

  • How do I not include part of a regular expression

    - by Axilus
    I'm pretty new to using regexes and I can figure out how I would go about extracted a specific number from a string. Suppose the string was any amount of whitespace or random text and somewhere within it is this, "Value: $1000.00." In order to retrieve that value I am currently using this: string value = Convert.ToString(Regex.Match(BodyContent, @"Value:[ \t]*\$?\d*(\.[0-9]{2})?", RegexOptions.Singleline)); So the variable 'value' now has, "Value: $1000.00" stored in it. My question is, using Regex is there a way to use 'Value:' to find the number value but only store the actual number value (i.e. 1000.00) in the 'value' variable?

  • How to proprely remove a flash object from a HTML page.

    - by Niklaos
    Hi guys. I made a website using AJAX (with jquery) for the navigation. The pages of the site are sliding and I use remove() to destroy the old page. Every thing seems alright, but some times the browser crashes when he tries to remove the old page containing a Flash object. I suppose this is because Flash is still executing the Flash object. My question is simple. How do i remove this Flash's object for my page without having the browser crashing on my face ? Is there a way to stop the Flash execution before removing the object ? Thanks for your help.

    - by Rbacarin

So now, the file has 50kb. I need a file with 25 Kb. Can anyone teach me any other way do save more space ? ps.: I Use 3 divs with some data, and 2 repeaters, one inside other, to generate a table with some data for me. thanks in advance

  • Regular Expression: Allow letters, numbers, and spaces (with at least one letter or number)

    - by makeee
    I'm currently using this regex ^[A-Z0-9 _]*$ to accept letters, numbers, spaces and underscores. I need to modify it to require at least one number or letter somewhere in the string. Any help would be appreciated! This would be for validating usernames for my website. I'd actually like to support as many characters as I can, but just want to ensure that I prevent code injection and that characters will display fine for all users. So I'm definately open to regex validation suggestions that would support a wider set of characters.

  • Advanced text search in actionscript-return ALL nouns,adjectives and verbs..

    - by eco_bach
    Hi I know that as3 has some powerful new text search capabilities, especially when combined with regex. I don't even know if this is possible, but I would like to somehow, search any block of text, and return all nouns, adjectives and verbs. What would be the best(most efficent) way to do this? Is regex an option? or would I have to load in some sort of open sourced dictionary 9as used in spellcheckers) to compare with or?? After, I've pulled all the nouns, adjectives and verbs, I need to count and prioritize by their frequency. Any suggestions welcome...

  • How do i hide html until its processed with javascript?

    - by acidzombie24
    I am using some JS code to transform my menu into a drilldown menu. The problem is before it runs the JS you see a BIG UGLY mess of links. On their site its solved by putting the js at the top. Using recommendations by yahoo/YSlow i am keeping the JS files at the bottom. I tried hiding the menu with display:none then using jquery to .show(), .css('display', ''), .css('display', 'block') and they all lead up to a messsed up looking menu (i get the title but not the title background color or any links of the menu) How do i properly hide a div/menu and show it after being rendered?

  • Using Regular Expressions

    - by bebeTech
    I am having problems trying to use the regular expression that I used in JavaScript. On a web page, you may have: <b>Renewal Date:</b> 03 May 2010</td> I just want to be able to pull out the 03 May 2010, remembering that a webpage has more than just the above content. The way I currently perform this using JavaScript is: DateStr = /<b>Renewal Date:<\/b>(.+?)<\/td>/.exec(returnedHTMLPage); I tried to follow some tutorials on java.util.regex.Pattern and java.util.regex.Matcher with no luck. I can't seem to be able to translate (.+?) into something they can understand?? thanks, Noeneel

  • Javascript split with RegEx

    - by Rohan
    Hey again, I just asked a question about Regex, and received a great answer: http://stackoverflow.com/questions/3047201/javascript-split-without-losing-character Now, I have another question. My current Regex looks like this: var split = text.split(/(?=\w*\d*\d:\d\d)/); Basically, I'm trying to split using the timestamps (eg - 9:30 or 10:30, the difference between them is the extra digit in the latter). How do I go about this? Currently, if I have these two: 9:30 pm The user did action A. 10:30 pm Welcome, user John Doe. The splits are : 9:30 pm The user did action A. ---- 1 ---- 0:30 pm Welcome, user John Doe. How do I add an optional check for the first character in the timestamp? Thanks!

  • different behavior when using re.finditer and re.match.

    - by Shahzad
    Hi, I'm working on a regex to to collect some values from a page through some script. I'm using re.match in condition but it returns false but if i use finditer it returns true and body of condition is executed. i tested that regex in my own built tester and it's working there but not in script. here is sample script. result = [] RE_Add0 = re.compile("\d{5}(?:(?:-| |)\d{4})?", re.IGNORECASE) each = ''Expiration Date:\n05/31/1996\nBusiness Address: 23901 CALABASAS ROAD #2000 CALABASAS, CA 91302\n' if RE_Add0.match(each): result0 = RE_Add0.match(each).group(0) print result0 if len(result0) < 100: result.append(result0) else: print 'Address ignore' else: None

  • Preloading images in HTML, is there a more modern way?

    - by John
    I have an image loaded by JS on a mouse event. It's a fairly big image so I want to make sure it gets pre-loaded. I reemmber some old techniques from years ago and found this example: <SCRIPT LANGUAGE = JAVASCRIPT> if (document.images) { img1 = new Image(); img2 = new Image(); img1.src = "imageName1.gif"; img2.src = "imageName2.gif" } </SCRIPT> I wondered if this is still good/relevant, or maybe browsers automatically detect unused images and preload them anyway? Note my page has to support IE6, so I might still need older techniques anyway, but I'm still interested if more modern browsers have a better way?
