• [Java] Cut <br/>-Tags from String end

  - by Robert M.

  Hello everybody, I am currently developing a Web-Application using Java EE where I'm using a Rich-Javascript-Editor (http://www.primefaces.org/showcase/ui/editor.jsf). As the user can easily add too many linebreaks that will be convertet to linebreak-tags, I need to remove all these Tags from the end of a String. Is there an elegant way of using Regex to accomplish this? An example String would be: "This is a test <b>bold</b><br/><br/>" Where obviously the last two tags have to be removed. Thank you in advance for any help Best Regards, Robert

• PHP if string contains URL isolate it

  - by Dylan Taylor

  In PHP, I need to be able to figure out if a string contains a URL. If there is a URL, I need to isolate it as another separate string. For example: "SESAC showin the Love! http://twitpic.com/1uk7fi" I need to be able to isolate the URL in that string into a new string. At the same time the URL needs to be kept intact in the original string. Follow? I know this is probably really simple but it's killing me.

• finding and returning a string with a specified prefix

  - by tipu

  I am close but I am not sure what to do with the restuling match object. If I do p = re.search('[/@.* /]', str) I'll get any words that start with @ and end up with a space. This is what I want. However this returns a Match object that I dont' know what to do with. What's the most computationally efficient way of finding and returning a string which is prefixed with a @? For example, "Hi there @guy" After doing the proper calculations, I would be returned guy

• How to invert alternate bits of a number

  - by Cupidvogel

  The problem is how to invert alternate bits of a number, starting from the LSB. Currently what I am doing is first doing a count = -1 while n: n >>= 1 count += 1 to first find the position of the leftmost set bit, then running a loop to invert every alternate bit: i = 0 while i <= count: num ^= 1<<i i += 2 Is there a quick hack solution instead of this rather boring loop solution? Of course, the solution can't make any asumption about the size of the integer.

• How do I select and group by a portion of a string?

  - by Russ Bradberry

  Given I have data like the following, how can I select and group by portions of a string? Version Users 1.1.1 1 1.1.23 3 1.1.45 1 2.1.24 3 2.1.12 1 2.1.45 3 3.1.10 1 3.1.23 3 What I want is to sum up the users using version 1.1.x and 2.2.x and 3.3.x etc, but I'm not sure how I can group on a partial string in a select statement. edit What the data should return like is this: Version Users 1.1.XX 5 2.1.XX 7 3.1.XX 4 There is an infinite variable number of versions, some are in this format (major, minor, build) some are just major, minor and some are just major, the only time I want to "roll up" the versions is when there is a build.

• Bitfield mask/operations with optional items

  - by user1560249

  I'm trying to find a way to handle several bitfield cases that include optional, required, and not allowed positions. yy?nnn?y 11000001 ?yyy?nnn 01110000 nn?yyy?n 00011100 ?nnn?yyy 00000111 In these four cases, the ? indicates that the bit can be either 1 or 0 while y indicates a 1 is required and n indicates that a 0 is required. The bits to the left/right of the required bits can be anything and the remaining bits must be 0. Is there a masking method I can use to test if an input bit set satisfies one of these cases?

• What is the faster way of trying to find a single character on a String?

  - by vtortola

  Hi, What of this code is faster/more efficient? : Boolean contains = myString.IndexOf("~", StringComparision.InvariantCultureIgnoreCase)!=-1; or Boolean contains = myString.IndexOf('~')!=-1; I think the second because is a single character, but using the invariant culture ignore case comparer is supposed to be fast too :P Cheers.

• Pre-formatting text to prevent reflowing

  - by mattjn

  I've written a fairly simple script that will take elements (in this case, <p> elements are the main concern) and type their contents out like a typewriter, one by one. The problem is that as it types, when it reaches the edge of the container mid-word, it reflows the text and jumps to the next line (like word wrap in any text editor). This is, of course, expected behavior; however, I would like to pre-format the text so that this does not happen. I figure that inserting <br> before the word that will wrap would be the best solution, but I'm not quite sure what the best way to go about doing that is that supports all font sizes and container widths, while also keeping any HTML tags intact. I figure something involving a hidden <span> element, adding text to it gradually and checking its width against the container width might be on the right track, but I'm not quite sure how to actually put this together. Any help or suggestions on better methods would be appreciated.

• How does one concatenate database values into a string?

  - by ggg

  I would like to string together database values into a string. Something like $a "text" $b. And then use the entire string as a variable, let's say $c. Is it better to do this at the database level? Will php use lots of resources to do this?

• Removing a pattern from the beggining and end of a string in ruby

  - by seaneshbaugh

  So I found myself needing to remove <br /> tags from the beginning and end of strings in a project I'm working on. I made a quick little method that does what I need it to do but I'm not convinced it's the best way to go about doing this sort of thing. I suspect there's probably a handy regular expression I can use to do it in only a couple of lines. Here's what I got: def remove_breaks(text) if text != nil and text != "" text.strip! index = text.rindex("<br />") while index != nil and index == text.length - 6 text = text[0, text.length - 6] text.strip! index = text.rindex("<br />") end text.strip! index = text.index("<br />") while index != nil and index == 0 text = test[6, text.length] text.strip! index = text.index("<br />") end end return text end Now the "<br />" could really be anything, and it'd probably be more useful to make a general use function that takes as an argument the string that needs to be stripped from the beginning and end. I'm open to any suggestions on how to make this cleaner because this just seems like it can be improved.

• In C/C++ what's the simplest way to reverse the order of bits in a byte?

  - by nathan

  While there are multiple ways to reverse bit order in a byte, I'm curious as to what is the "simplest" for a developer to implement. And by reversing I mean: 1110 -> 0111 0010 -> 0100 This is similar to, but not a duplicate of this PHP question.

• Replace string with incremented value

  - by Andrei

  Hello, I'm trying to write a CSS parser to automatically dispatch URLs in background images to different subdomains in order to parallelize downloads. Basically, I want to replace things like url(/assets/some-background-image.png) with url(http://assets[increment].domain.com/assets/some-background-image.png) I'm using this inside a class that I eventually want to evolve into doing various CSS parsing tasks. Here are the relevant parts of the class : private function parallelizeDownloads(){ static $counter = 1; $newURL = "url(http://assets".$counter.".domain.com"; The counter needs to be reset when it reaches 4 in order to limit to 4 subdomains. if ($counter == 4) { $counter = 1; } $counter ++; return $newURL; } public function replaceURLs() { This is mostly nonsense, but I know the code I'm looking for looks somewhat like this. Note : $this-css contains the CSS string. preg_match("/url/i",$this->css,$match); foreach($match as $URL) { $newURL = self::parallelizeDownloads(); $this->css = str_replace($match, $newURL,$this->css); } }

• On-the-fly thumbnails PHP

  - by Wayne

  I came up with this: <?php $dir = $_GET['dir']; header('Content-type: image/jpeg'); $create = imagecreatetruecolor(150, 150); $img = imagecreatefromjpeg($dir); imagecopyresampled($create, $img, 0, 0, 0, 0, 150, 150, 150, 150); imagejpeg($create, null, 100); ?> It works by accessing: http://domain.com/image.php?dir=thisistheimage.jpg Which works fine... but the output is awful: Can someone fix my code for the image to be 150 x 150 covering the black area... Thanks.

• How to find image width and height dynamically and specify height, width attibutes if over certain d

  - by Wbdvlpr

  Hi, I display some data on my website and one of the data feed elements is an image. [title] => Product title [description] => some description [image] => www.some-domain.com/product-image/p12345.jpg I then display this image using <img alt="product" src="<?=$data['image']?>" /> Most of the images are 80x80, 120x100 or other less than 150 in width, which perfectly fit in the website template, but some of them are quite large such as 800x600 which distort the layout. I want a control on these types. I tried to set WIDTH="150", but as the width vary they dont look good. I was thinking If I could set a fixed width to images, say, larger than 250px then I can live with it for now. Any ideas how to achieve this? Thanks
