  • How to get regular expression matches between two boundaries

    - by Rubans
    Hi, I have the following text: started: Project: ProjectA, Configuration: Release Any CPU ------ I would like to get just the actual project name which in this example is "ProjectA". I do have a regular expression "started:(\s)Project:(\s).*," which will give me "started: Project: ProjectA," and then I can use further basic string searching to return the project name but was wondering if there is any way I can just grab the actual project name without doing the extra string searching, maybe using a correct regular expression. What I need is the string value between boundaries "started: Project: " and ",". Any ideas?

  • Java Preprocessor in C#

    - by Olaseni
    Say I want to create a sort of Pre-processor for existing java code, so I can get the language specific keywords and objects, and then create routines that convert them to their Csharp equivalents, using Csharp code - what route should this take? I'm thinking of Regular Expressions, but I'm fuzzed. I have a bunch of about a 100 .java files and I need to convert them to csharp code in record time. I have manually done just about five of them and I have serious headaches already. Or are there any tools out there that already do that?

  • Evaluating a regular expression range

    - by Dan Atkinson
    Hi there! Is there a nice way to evaluate a regular expression range, say, for a url such as http://example.com/[a-z]/[0-9].htm This would be converted into: http://example.com/a/0.htm http://example.com/a/1.htm http://example.com/a/2.htm ... http://example.com/a/9.htm ... http://example.com/z/0.htm http://example.com/z/1.htm http://example.com/z/2.htm ... http://example.com/z/9.htm I've been scratching my head about this, and there's no pretty way of doing it without going through the alphabet and looping through numbers. Thanks in advance!

  • Function to hide sloppy phone numbers..

    - by Frank Malina
    I need to hide phone numbers (and maybe other contact details) in user generated content to protect my users from anonymous web. Input is very random, therefore I'd be looking to replace anything that looks like a phone number (e.g.: string of 3 or more numbers) with just dots, and also perhaps remove some exotic notations of e-mail addresses. What is the best way to do this? Nice and slick, reusable. Give away your secret regexes. Write in any language. Except perhaps COBOL :) function privacy($str){ // protect phone numbers // protect e-mail addresses // protect web addresses }

  • Need MySQL RLIKE expression to exclude certain strings ending in particular characters...

    - by user299508
    So I've been working with RLIKE to pull some data in a new application and mostly enjoying it. To date I've been using RLIKE queries to return 3 types of results (files, directories and everything). The queries (and example results) follow: **All**: SELECT * FROM public WHERE obj_owner_id='test' AND obj_namespace RLIKE '^user/test/public/[-0-9a-z_./]+$' ORDER BY obj_namespace user/test/public/a-test/.comment user/test/public/a-test/.delete user/test/public/directory/ user/test/public/directory/image.jpg user/test/public/index user/test/public/site-rip user/test/public/site-rip2 user/test/public/test-a user/test/public/widget-test **Files**: SELECT * FROM public WHERE obj_owner_id='test' AND obj_namespace RLIKE '^user/test/public/[-0-9a-z_./]+[-0-9a-z_.]+$' ORDER BY obj_namespace user/test/public/a-test/.comment user/test/public/a-test/.delete user/test/public/directory/image.jpg user/test/public/index user/test/public/site-rip user/test/public/site-rip2 user/test/public/test-a user/test/public/widget-test **Directories**: SELECT * FROM public WHERE obj_owner_id='test' AND obj_namespace RLIKE '^user/test/public/[-0-9a-z_./]+/$' ORDER BY obj_namespace user/test/public/directory/ This works well for the above 3 basic scenarios but under certain situations I'll be including special 'suffixes' I'd like to be excluded from the results of queries (without having to resort to PHP functions to do it). A good example of such a string would be: user/test/public/a-test/.delete That data (there are more rows then just obj_namespace) is considered deleted and in the Files and All type queries I'd like it to be omitted within the expression if possible. Same goes for the /.comments and all such meta data will always be in the same format: /.[sometext] I'd hoped to use this feature extensively throughout my application, so I'm hoping there might be a very simple answer. (crosses fingers) Anyway, thanks as always for any/all responses and feedback.

  • How can I make a case-insensitive regexp match for Russian letters?

    - by jonny
    I have list of catalog paths and need to filter out some of them. My match pattern is in a non-Unicode encoding. I tried the following: require 5.004; use POSIX qw(locale_h); my $old_locale = setlocale(LC_ALL); setlocale(LC_ALL, "ru_RU.cp1251"); @{$data -> {doc_folder_rights}} = grep { # catalog path pattern in $_REQUEST{q} $_->{doc_folder} =~/$_REQUEST{q}/i; } @{$data -> {doc_folder_rights}}; setlocale(LC_ALL, $old_locale); What I need is case-insensitive regexp pattern matching when pattern contains russsian letters.

  • How can I implement Unix grep in Perl?

    - by Ankit Rathod
    How can I implement grep of Unix in Perl? I tried to use Perl's built-in grep. Here is the code which is not working: $pattern = @ARGV[0]; $file= @ARGV[1]; open($fp,$file); @arr = <$fp>; @lines = grep $pattern, @arr; close($fp); print @lines; And by the way, i am trying only basic grep functionality not full featured and secondly i don't want to do string parsing myself. I want to use inbuilt grep or some function of Perl. Thanks in advance :)

  • How do you comment html templates in Php (in a practical way) ?

    - by faB
    Is there a simple solution to do the equivalent of Java's comments: <%-- this is a comment inside a template, it does not appear in the output HTML --%> Even if you use short php tags, you still have to wrap the comments with comment syntax, on top of the php tags: <? /* this is a comment of the html template */ ?> I'm considering doing some kind of filter on the output templates, to remove all html comments, or better yet, custom comments like the Java syntax above, but how would you do that in the most efficient way? You'd have to run a regexp right? The reason for my question is simply that in a MVC framrwork, using components, and re-usable html templates (think YUI), I need to document clearly those templates, in a readable way..

  • RegExp: want to find all links that do not end in ".html"

    - by grovel
    Hi, I'm a relative novice to regular expressions (although I've used them many times successfully). I want to find all links in a document that do not end in ".html" The regular expression I came up with is: href=\"([^"]*)(?<!html)\" In Notepad++, my editor, href=\"([^"]*)\" finds all the links (both those that end in "html" and those that do not). Why doesn't negative lookbehind work? I've also tried lookahead: href=\"[^"]*(?!html\") but that didn't work either. Can anybody help? Cheers, grovel

  • Finding duplicate files by content across multiple directories

    - by gagneet
    I have downloaded some files from the internet related to a particular topic. Now I wish to check if the files have any duplicates. The issue is that the names of the files would be different, but the content may match. Is there any way to implement some code, which will iterate through the multiple folders and inform which of the files are duplicates?

  • PHP regular expression find and append to string

    - by Gary
    I'm trying to use regular expressions (preg_match and preg_replace) to do the following: Find a string like this: {%title=append me to the title%} Then extract out the title part and the append me to the title part. Which I can then use to perform a str_replace(), etc. Given that I'm terrible at regular expressions, my code is failing... preg_match('/\{\%title\=(\w+.)\%\}/', $string, $matches); What pattern do I need? :/

  • AJAX - querying a search engine and returning the number of results

    - by Moddy
    Right, so basically I need to query a selection of search engines in an AJAX app. As there is a number of different search engines - there's no search engine specific API I can use either. My main problem is getting the number of results returned by the search. So far, I have decided it is probably best to use a regexp from the returned search query HTML, and then convert the string of characters to an integer. However, this method just doesn't feel.. clean to me. It seems a bit rough around the edges and I think it could do with improving! I guess not being 100% confident with regular expressions doesn't help; but it just feels like it could be improved. Any ideas on how to implement this would be great cheers! It doesn't seem like that an exotic thing to do, so I was wondering if perhaps any of you guys have done this before and would have a few tips? Note: This is an AJAX app at the moment, but I may be re-writing this functionality in a different app soon - which won't be AJAX. I'm confident I can transfer any AJAX implementation to the other language though.

  • Regular expression to extract text between either square or curly brackets

    - by ObiWanKenobi
    Related to my previous question, I have a string on the following format: this {is} a [sample] string with [some] {special} words. [another one] What is the regular expression to extract the words within either square or curly brackets, ie. {is} [sample] [some] {special} [another one] Note: In my use case, brackets cannot be nested. I would also like to keep the enclosing characters, so that I can tell the difference between them when processing the results.

  • Practical non-Turing-complete languages?

    - by Kyle Cronin
    Nearly all programming languages used are Turing Complete, and while this affords the language to represent any computable algorithm, it also comes with its own set of problems. Seeing as all the algorithms I write are intended to halt, I would like to be able to represent them in a language that guarantees they will halt. Regular expressions used for matching strings and finite state machines are used when lexing, but I'm wondering if there's a more general, broadly language that's not Turing complete? edit: I should clarify, by 'general purpose' I don't necessarily want to be able to write all halting algorithms in the language (I don't think that such a language would exist) but I suspect that there are common threads in halting proofs that can be generalized to produce a language in which all algorithms are guaranteed to halt. There's also another way to tackle this problem - eliminate the need for theoretically infinite memory. Once you limit the amount of memory the machine is allowed, the number of states the machine is in is finite and countable, and therefore you can determine if the algorithm will halt (by not allowing the machine to move into a state it's been in before).

  • regular expression

    - by Jeeenda
    Hi I need a regular expression that'll give me something like this part ./something\", [something.sh from something like this string ("./something\", [something.sh", ["./something\", [something.sh"], [/* 37 vars */]) is that possible? I'm having real trouble making this since there's that \" escape sequence and also that ',' character, so I cannot simply use match everything instead of these characters. I'm working on unix so it's also possible to use pipeline of few greps or something like that. Thanks for advice.

  • Split a html string in N parts

    - by Matt Brailsford
    Hi Guys, Does anybody have an example of spliting a html string (coming from a tiny mce editor) and splitting it into N parts using C#? I need to split the string evenly without splitting words. I was thinking of just splitting the html and using the HtmlAgilityPack to try and fix the broken tags. Though I'm not sure how to find the split point, as Ideally it should be based purley on the text rather than the html aswell. Anybody got any ideas on how to go about this? Many thanks Matt
