  • [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

I tried to use s.replace(), but as it's not in place change, I ran as follows to get a wrong anwser. path1 = "/Users/smcho/Desktop/bracket/[10,20]" path2 = path1.replace('[','[[]') path3 = path2.replace(']','[]]') pathName = os.path.join(path3, "*.txt") print pathName -- /Users/smcho/Desktop/bracket/[[[]]10,20[]]/*.txt How can I do the multiple replace in python? Or how can I replace '[' and ']' at the same time?

  • Split string into smaller part with constrain [PHP RegEx HTML]

    - by Sadi
    Hello, I need to split long string into a array with following constrains: Each part will have a limited number of character (e.g. not more than 8000 character) Each part can contain multiple sentences (delimited by . [full stop]) but never a partial sentences. Except if the last part of the string (as last part may not have any full stop. The string may contain HTML tags. But the tag can not be divided as ( to ). That means HTML tag should be intact. But starting tag and ending tag can be stay on different segment/chunk. I think regular expression with preg_split can do it. Would please help me with the proper RegEx. Thank you Sadi

  • How to remove characters from a string?

    - by masato-san
    Hi, Below is interview question so you cannot relay on the functions that predefined in libraries. Also my answer below set the element to null but there is another ways to solve the problem. Given string $string = "This is a pen", remove "is" so that return value is "Th a pen" (including whitespece). I've tried (shown below) but returned value is not correct. Thanks in advance! function remove_delimiter_from_string(&$string, $del) { for($i=0; $i<strlen($string); $i++) { for($j=0; $j<strlen($del); $j++) { if($string[$i] == $del[$j]) { $string[$i] = $string[$i+$j]; //this grabs delimiter :( } } } echo $string . "\n"; }

  • 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?

  • 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

  • Split String in C# without delimiter (sort of)

    - by Zach
    Hi, I want to split a string in C#.NET that looks like this: string Letters = "hello"; and put each letter (h, e, l, l, o) into an array or ArrayList. I have no idea what to use as the delimiter in String.Split(delimiter). I can do it if the original string has commas (or anything else): string Letters = "H,e,l,l,o"; string[] AllLettersArray = Letters.Split(",".ToCharArray()); But I have no idea what to use in a case with (supposedly) no delimiter. Is there a special character like Environment.Newline? Thanks.

  • Why does the output look like this?

    - by cjk
    I have a c program below, I would like to send out a 32 bit message in a particular order Eg.0x00000001. #include <unistd.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <sys/types.h> #include <stdint.h> struct test { uint16_t a; uint16_t b; }; int main(int argc, char const *argv[]) { char buf[4]; struct test* ptr=(struct test*)buf; ptr->a=0x0000; ptr->b=0x0001; printf("%x %x\n",buf[0],buf[1]); //output is 0 0 printf("%x %x\n",buf[2],buf[3]); //output is 1 0 return 0; } Then I test it by print out the values in char array. I got output in the above comments. Shouldn't the output be 0 0 and 0 1? since but[3] is the last byte? Is there anything I missed? Thanks!

  • 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.

  • 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.

  • 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.

  • 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); } }

  • 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.
