• PHP DOMXml XPath of recursive Xpointer

  - by user256007

  My xml document reflects an Object. as referential Recursion is possible in objects and arrays. I need to reflect that in reproduced XML Structure too. Currently I am using Unique IDs to identify each node separately and a node like <recursion refer="IDREF"> and specifying the ID of the referenced Element. But in This way I need My Own Custom XPath resolver cause I want to let the users go deeper into the recursive node through the Identifying IDREF (Hope I am able to make you understand). So is there any better/liteweight solution ?? might be XPointer or XLink (I am not sure). Any help ??

• Dealing with multiple parameters in Nginx rewrite

  - by x3sphere

  I have a rewrite that nginx calls like so: location ~* (css)$ { rewrite ^(.*),(.*)$ /min/index.php?f=$1,/min/$2 last; } And it's used on pages like this: http://domain.com/min/framework.css,dropdown.css Works all fine and dandy, but it's not scalable. Adding another element to the URL means I have to directly edit the nginx config. Ideally, I'd like to have nginx rewrite according to how many comma-delimited parameters are passed through the URL, rather than setting a fixed amount in the config. Is this possible?

• Simple Custom rule for Jquery validator

  - by thatweblook

  Hi, I read your reply regarding the jQuery validator where you outline a method to check a username against a value in a database. Ive tried implementing this method but no matter what is returned from the PHP file I always get the message that the username is already taken. Here is ths custom method... $.validator.addMethod("uniqueUserName", function(value, element) { $.ajax({ type: "POST", url: "php/get_save_status.php", data: "checkUsername="+value, dataType:"html", success: function(msg) { // if the user exists, it returns a string "true" if(msg == "true") return false; // already exists return true; // username is free to use } })}, "Username is Already Taken"); And here is the validate code... username: { required: true, uniqueUserName: true }, Is there a specific way i am supposed to return the message from php. Thanks A

• Safari anchors on links not working.

  - by Keyo

  My html anchor is as follows. <a name="template-8"/> <h4 class="template" id="template-8">A title</h4> As far as I know the browser should skip to the element matching either name or id attributes. When I type in the url http://my.site.com/templates#template-8 safari jumps down the page as expected. However when linking as below the anchor does nothing. Chrome, Opera, IE7 and Firefox all work. <a href="http://my.site.com/templates#template-8">A link</a> Safari is version 5.0, could this be a safari bug?

  - 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

• Easiest way to create twitter-like status update widget

  - by culov

  I want a widget that allows users to add a request if that request hasnt already been added, or vote for a request if it has already been added. when a user adds a request, i want it to immediately appear as the first element of the list, like what would happen to your timeline if you made new tweet. ive tried to look for a jquery plugin that offers this functionality, but i was unsuccessful (maybe i couldnt think of the right terms to search for??). i dont have enough faith in my js skills to write this from scratch, so id rather find a template to start with. Thanks.

• Performance Improvement: Alternative for array_flip function.

  - by Rachel

  Is there any way I can avoid using array_flip to optimize performance. I am doing a select statement from database, preparing the query and executing it and storing data as an associative array in $resultCollection and than I have array op and for each element in $resultCollection am storing its outputId in op[] as evident from the code. I have explained code and so my question is how can I achieve an similar alternative for array_flip with using array_flip as I want to improve performance. $resultCollection = $statement->fetchAll(PDO::FETCH_ASSOC); $op = array(); //Looping through result collection and storing unicaOfferId into op array. foreach ($resultCollection as $output) { $op[] = $output['outputId']; } //Here op array has key as 0, 1, 2...and value as id {which I am interested in} //Flip op array to get unica offer ids as key $op = array_flip($op); //Doing a flip to get id as key. foreach ($ft as $Id => $Off) { $ft[$Id]['is_set'] = isset($op[$Id]); }

• PHP Curl and Loop based on a numeric value

  - by danit

  Im using the Twitter API to collect the number of tweets I've favorited, well to be accurate the total pages of favorited tweets. I use this URL: http://api.twitter.com/1/users/show/username.xml I grab the XML element 'favorites_count' For this example lets assume favorites_count=5 The Twitter API uses this URL to get the favorties: http://twitter.com/favorites.xml (Must be authenticated) You can only get the last 20 favorties using this URL, however you can alter the URL to include a 'page' option by adding: ?page=3 to the end of the favorites URL e.g. http://twitter.com/favorites.xml?page=2 So what I need to do is use CURL (I think) to collect the favorite tweets, but using the URL: http://twitter.com/favorites.xml?page=1 http://twitter.com/favorites.xml?page=2 http://twitter.com/favorites.xml?page=3 http://twitter.com/favorites.xml?page=4 etc... Some kind of loop to visit each URL, and collect the Tweets and then output the cotents. Can anyone help with this: - Need to use CURL to authenticate - Collect the number of pages of tweets (Already scripted this) - Then use a loop to go through each page URL based on the pages value?

• Drupal 6 / Views2 Grid style: whole cells link to nodes

  - by jackocnr

  I have a Users page, which is simply a nicely styled grid (HTML table) of users. I'm displaying a few fields for each one, and both the name and the profile picture have been set to link to the user node. What is the best way to change it so that the whole cell (HTML td) links to the user node? Would you have to use javascript? I've looked into modifying the theme of the view (over-riding the Style output e.g. views-view-grid--users.tpl.php), but cant see an elegant way to get the URL of the user node. And I think you would have to use javascript anyway to turn a whole block element into a link.

• Expression Tree

  - by nettguy

  My understanding of expression tree is : Expression trees are in-memory representation of expression like arithmetic or boolean expression.The expressions are stored into the parsed tree.so we can easily transalate into any other language. Linq to SQL uses expression tree.Normally in LINQ to SQL query the compiler translates it into parsed expression trees.These are passed to Sql Server as T-SQL Statements.The Sql server executes the T-SQL query and sends down the result back.That is why when you execute LINQ to SQL you gets IQueryable<T> not IEnumetrable<T>.Because IQuerybale contains public IQueryable:IEnumerable { Type Element {get;} Expression Expression {get;} IQueryaleProvider Provider {get;} } Questions : Microsoft uses Expression trees to play with LINQ-to-Sql.What are the different ways can i use expression trees to boost my code. Apart from LINQ to SQL,Linq to amazon ,who used expression trees in their applications? Linq to Object return IEnumerable,Linq to SQL return IQueryable ,What does LINQ to XML return?

• jQuery val not working properly in Chrome

  - by Mircea

  I have a simple jQuery function: $('#selectable1 span').live('mousedown', function() { var ff = $(this).css("font-family"); $("#family").val(ff); }); When a span element is clicked (mousedown) an input (#family) gets its font family value. It works in FireFox but in Chrome it works only for font families composed from only one word. Georgia will work but Times New Roman will now. You can see the code here: http://jsfiddle.net/aLaGa/ or live at http://www.typefolly.com What is wrong with this? Thanx

• How fast can you make linear search?

  - by Mark Probst

  I'm looking to optimize this linear search: static int linear (const int *arr, int n, int key) { int i = 0; while (i < n) { if (arr [i] >= key) break; ++i; } return i; } The array is sorted and the function is supposed to return the index of the first element that is greater or equal to the key. They array is not large (below 200 elements) and will be prepared once for a large number of searches. Array elements after the n-th can if necessary be initialized to something appropriate, if that speeds up the search. No, binary search is not allowed, only linear search.

• java xml pretty printing - preserve empty elements and white pace

  - by javamonkey79

  Basically, I am looking for a java library that will take this: <foo><bar> </bar><baz>yadda</baz></foo> And pretty print it to this: <?xml version="1.0" encoding="UTF-8"?> <foo> <bar> </bar> <baz>yadda</baz> </foo> e.g. preserving whitespace AND blank elements The closest I have got was with dom4j like so: OutputFormat format = OutputFormat.createPrettyPrint(); format.setTrimText( false ); However, this does not honor the whitespace unless the element contains other character data. I'm not opposed to writing something on my own, but I would think this has already been done, why reinvent the wheel?

• Vertical centering text (jQuery)

  - by Nimbuz

  <div style="width: 100px; height:50px; line-height:50px; overflow:hidden;"> <p>A short line</p> </div> <div style="width: 100px; height:50px; line-height:50px; overflow:hidden;"> <p>A really really really long line</p> </div> Wrapped text in the second example gets cut off because of the line-height:50px which should be 25px in this case. How do I use jQuery to find if theres single or multi-line text in an element? Thanks!

• Hex to Decimal conversion in C

  - by darkie15

  Hi All, Here is my code which is doing the conversion from hex to decimal. The hex values are stored in a unsigned char array: int liIndex ; long hexToDec ; unsigned char length[4]; for (liIndex = 0; liIndex < 4 ; liIndex++) { length[liIndex]= (unsigned char) *content; printf("\n Hex value is %.2x", length[liIndex]); content++; } hexToDec = strtol(length, NULL, 16); Each array element contains 1 byte of information and I have read 4 bytes. When I execute it, here is the output that I get : Hex value is 00 Hex value is 00 Hex value is 00 Hex value is 01 Chunk length is 0 Can any one please help me understand the error here. Th decimal value should have come out as 1 instead of 0. Regards, darkie

• Arrays of pointers to arrays?

  - by a2h

  I'm using a library which for one certain feature involves variables like so: extern const u8 foo[]; extern const u8 bar[]; I am not allowed to rename these variables in any way. However, I like to be able to access these variables through an array (or other similar method) so that I do not need to continually hardcode new instances of these variables into my main code. My first attempt at creating an array is as follows: const u8* pl[] = { &foo, &bar }; This gave me the error cannot convert 'const u8 (*)[]' to 'const u8*' in initialization, and with help elsewhere along with some Googling, I changed my array to this: u8 (*pl)[] = { &foo, &bar }; Upon compiling I now get the error scalar object 'pl' requires one element in initializer. Does anyone have any ideas on what I'm doing wrong? Thanks.

• Database Replication OOD Pattern

  - by MrOnigiri

  Greetings fellow overflowers, After reading on MSDN about correct strategies on how to perform database replication, and understanding their suggestion on Master-Subordinate Incremental Replication. It left me wondering, what OOD design pattern should I use on this... The main elements of this strategy are the Acquirer, the Manipulator and the Writer. The first fetches data from the database and passes on to the second which might perform simple transformations to the data, before handling it to the final element, the writer, that writes the desired data on the destination Database. I thought about using the Chain of Responsibility pattern, but the Acquirer, Manipulator and Writer don't share a common role among theme, so It makes no sense. Should these elements be written as separate classes, or methods inside my service? Of course I'll be creating a DB Helper class as well, but that doesn't constitutes a problem. Wondering what your opinions on this are! Thanks for your replies

• How to actually use ZeroClipboard in jQuery?

  - by Martti Laine

  Hello I just can't get this thing. How is ZeroClipboard supposed to work? Why does it need to move the flash-element over the copied text? I've read this thing: http://code.google.com/p/zeroclipboard/wiki/Instructions Can someone provide me a short snippet, which makes it possible to copy a text in variable to users clipboard, when user clicks a link. Is this even possible? I don't care, if it doesn't work on all browsers (IE6 for example). I'm using jQuery. Martti Laine

• How do i create an array of unequal length arrays?

  - by Faken

  Hello everyone, I need to create a sort of 2D array in which each one of the secondary arrays are of different length. I have a 1D array of known length (which defines the number of arrays to be formed) with each element having a number that denotes the length of the secondary array in that position. Each one of the arrays are fairly large so i don't want to create a one-size-fits-all "fake" 2D heap array to cover everything. How would i go about doing this? Any 2D array I have made before are always rectangular. I'm trying to do this so that i can create some code to dynamically generate threads to split up some workload. Thanks, -Faken
