  • JavaScript regex refactoring

    - by JamesBrownIsDead
    I'm performing this on a string: var poo = poo .replace(/[%][<]/g, "'<") .replace(/[>][%]/g, ">'") .replace(/[%]\s*[+]/g, "'+") .replace(/[+]\s*[%]/g, "+'"); Given the similar if these statements, can these regexs be comebined somehow?

  • python regex of a date in some text, enclosed by two keywords

    - by Horace Ho
    This is Part 2 of this question and thanks very much for David's answer. What if I need to extract dates which are bounded by two keywords? Example: text = "One 09 Jun 2011 Two 10 Dec 2012 Three 15 Jan 2015 End" Case 1 bounding keyboards: "One" and "Three" Result expected: ['09 Jun 2011', '10 Dec 2012'] Case 2 bounding keyboards: "Two" and "End" Result expected: ['10 Dec 2012', '15 Jan 2015'] Thanks!

  • Clean up domain list in Excel - regex / macros?

    - by Tim
    I have a huge spreadsheet of domains that I need to clean up as follows: Remove all http:// (simple replace all - "http://" with "") Remove any www. (simple replace all - "www." with "") Delete any sub-domains (delete the actual row completely, not just the subdomain from the url) Remove anything after the domain extension (i.e. website.com/blah/blahbah/ becomes just website.com (simple replace all - "/*" with "", then replace all "/" with "") So what I'm left with is just a spreadsheet of clean domains like "website.com". I think I've got 1, 2 and 4 sorted (as above), but I'm really struggling with 3. Any ideas? Can I do this with regexp / vba, and actually delete the row completely? Sample data: http://www.scholastic.com/kids/stacks/games/ http://imgworld.teamworkonline.com/ http://topfreegraphics.com/ http://www.workcircle.co.uk/ http://www.healthycanadians.gc.ca/index-eng.php http://gsociology.icaap.org/methods/soft.html Post 1, 2 and 4 would leave me with: scholastic.com imgworld.teamworkonline.com topfreegraphics.com workcircle.co.uk healthycanadians.gc.ca gsociology.icaap.org It's those pesky sub-domains I need to just delete completely, just delete the row. I've realised I can't just search for 2 x ".", because obviously plenty of domain extensions (i.e .co.uk) include that. Any help appreciated.

  • php regex filename

    - by Patrick
    Hi, anyone can help me with a preg_match? I'd like to use php's preg_match to determine if an input is a valid filename or not (only the filename + file extension, not the full path). General rules: 1) filename = a-z, A-Z, 0-9 2) extension = 3 or 4 letters Thank you!

  • Regex matching wrong strings

    - by Joe Smalley
    I have this PHP/SQL query: $sql = sprintf("SELECT * FROM %sCubeCart_filemanager WHERE filepath REGEXP '%s[\\/\\\\][^\\/\\\\]+$' AND type = '%d' AND disabled = '0' ORDER BY filepath ASC %s", $this->_config['dbprefix'], str_replace(array('\\','/'),'.',$folder), $type, $limit); if '$folder' == 'iha9' it is finding results like 'iha91' and 'iha99' too. Something is wrong with the regular expression, but I don't know how they work, can anyone help?!

  • Finding words strictly starting with $, Regex C#

    - by Anirudh Goel
    I need to find all matches of word which strictly begins with "$" and contains only digits. So I wrote [$]\d+ which gave me 4 matches for $10 $10 $20a a$20 so I thought of using word boundaries using \b: [$]\d+\b But it again matched a$20 for me. I tried \b[$]\d+\b but I failed. I'm looking for saying, ACCEPT ONLY IF THE WORD STARTS WITH $ and is followed by DIGITS. How do I tell IT STARTS WITH $, because I think \b is making it assume word boundaries which means surrounded inside alphanumeric characters. What is the solution?

  • utf-8 word boundary regex in javascript

    - by cherouvim
    In JavaScript: "ab abc cab ab ab".replace(/\bab\b/g, "AB"); correctly gives me: "AB abc cab AB AB" When I use utf-8 characters though: "aß aß? ?aß aß aß".replace(/\baß\b/g, "AB"); the word boundary operator doesn't seem to work: "aß aß? ?aß aß aß" Is there a solution to this?

  • Search for content in functions with regex

    - by Marlun
    Hello, How would I with regular expression search for functions which contains the use of a global variable without running "global $var" first? The files looks like this: class TestClass { function correctFunc() { global $var; $name = $var->name; } function invalidFuncIWantToFind() { $age = $var->user->age; } } I want to find the function names of all the invalidFuncIWantToFind. At work this would have really speeded up our work but I didn't get how to do it.

  • Java regex basic usage problem

    - by Ernelli
    The following code works: String str= "test with foo hoo"; Pattern pattern = Pattern.compile("foo"); Matcher matcher = pattern.matcher(str); if(matcher.find()) { ... } But this example does not: if(Pattern.matches("foo", str)) { ... } And neither this version: if(str.matches("foo")) { ... } In the real code, str is a chunk of text with multiple lines if that is treated differently by the matcher, also in the real code, replace will be used to replace a string of text. Anyway, it is strange that it works in the first version but not the other two versions.

  • php preg_match pattern to extract a specific information, regex

    - by Michael
    I need to extract a specific Id from a html document but the problem is that the id must not "be used". Here is the html content http://pastebin.com/wF2dx8JZ As you may see there are different html blocks . Some of them contain the "Used" word so I need to extract only the first id which is not used. Basically I can write a simple pattern like : $pattern = "/javascript:tw(.*))/"; preg_match_all($pattern, $content, $matches); $id = $matches[1][0]; However in this case I'm also getting the "ids" which are used so I don't know how to exclude them from the equation . Any idea would be highly appreciated.

  • Regex for recursive "wiki-style" lists

    - by Syd Miller
    I'm trying to create a Regular Expression to match "wiki style" lists as in (using preg_replace_callback() ): * List Item 1 * List Item 2 *# List Item 2.1 *# List Item 2.2 * List Item 3 Asterisks denote Unordered Lists while Number-Signs denote Ordered Lists. I'm trying to get this so it can match infinite depth and so that * and # can be mixed. I tried the following expression (and variations of it): /\s([*#]{1,}) ([\S ]+)\s/si But it doesn't seem to want to work. What am I doing wrong? Or is there a better way of accomplishing this?
