  • WordPress: Problem with the shortcode regex

    - by peroyomas
    This is the regular expression used for "shortcodes" in WordPress (one for the whole tag, other for the attributes). return '(.?)\[('.$tagregexp.')\b(.*?)(?:(\/))?\](?:(.+?)\[\/\2\])?(.?)'; $pattern = '/(\w+)\s*=\s*"([^"]*)"(?:\s|$)|(\w+)\s*=\s*\'([^\']*)\'(?:\s|$)|(\w+)\s*=\s*([^\s\'"]+)(?:\s|$)|"([^"]*)"(?:\s|$)|(\S+)(?:\s|$)/'; It parses stuff like [foo bar="baz"]content[/foo] or [foo /] In the WordPress trac they say it's a bit flawed, but my main problem is that it don't support shortcodes inside the attributes, like in [foo bar="[baz /]"]content[/foo] because the regex stops the main shortcode at the first appearance of a closing bracket, so in the example it renders [foo bar="[baz /] and "]content[/foo] shows as it is. Is there any way to change the regex so it bypass any ocurrence of [ with ] and its content when occurs between the opening tag or self-closing tag?

  • Regex for date.

    - by Harikrishna
    What should be the regex for matching date of any format like 26FEB2009 30 Jul 2009 27 Mar 2008 29/05/2008 27 Aug 2009 What should be the regular expression for that ? I have regex that matches with 26-Feb-2009 and 26 FEB 2009 with but not with 26FEB2009. So if any one know then please update it. (?:^|[^\d\w:])(?'day'\d{1,2})(?:-?st\s+|-?th\s+|-?rd\s+|-?nd\s+|-|\s+)(?'month'Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec)[uarychilestmbro]*(?:\s*,?\s*|-)(?:'?(?'year'\d{2})|(?'year'\d{4}))(?=$|[^\d\w]) EDIT The date 26FEB2009 is substring of other string like FUTIDX 26FEB2009 NIFTY 0 and parsed from html page, so I can not set the whitespace or delimiter.

  • What's wrong with my regex

    - by Tom Brown
    Yes I know its usually a bad idea to parse HTML using RegEx, but that aside can someone explain the fault here: string outputString = Regex.Replace(inputString, @"<?(?i:script|embed|object|frameset|frame|iframe|metalink|style|html|img|layer|ilayer|meta|applet)(.|\n)*?>", ""); if (outputString != inputString) { Console.WriteLine("unwanted tags detected"); } It certainly detects the intended tags like: <script> and <html>, but it also rejects strings I want to allow such as <B>Description</B> and <A href="http://www.mylink.com/index.html">A Link containing 'HTML'</A>

  • Regex matching very slow

    - by Ali Lown
    I am trying to parse a PDF to extract the text from it (please don't suggest any libraries to do this, as this is part of learning the format). I have already handled deflating it to put it in the alphanumeric format. I now need to extract the text from the text blocks. So, my current pattern is "BT.*?((.*?)).*?ET" (with DOTMATCHALL set) to match something like: BT /F13 12 Tf 288 720 Td (ABC) Tj ET The only bit I want is the text ABC in the brackets. The above pattern works, but is really slow, I assume it is because the regex library is failing to match the pattern that matches the text between BT and the (ABC) many times. The regex is pre-compiled in an attempt to speed it up, but it seems negligible. How may I speed this up?

  • RegEx for MetaMap in Java

    - by Christian
    MetaMap files have following lines: mappings([map(-1000,[ev(-1000,'C0018017','Objective','Goals',[objective],[inpr],[[[1,1],[1,1],0]],yes,no)])]). The format is explained as mappings( [map(negated overall score for this mapping, [ev(negated candidate score,'UMLS concept ID','UMLS concept','preferred name for concept - may or may not be different', [matched word or words lowercased that this candidate matches in the phrase - comma separated list], [semantic type(s) - comma separated list], [match map list - see below],candidate involved with head of phrase - yes or no, is this an overmatch - yes or no ) ] ) ] ). I want to run a RegEx query in java that gives me the Strings 'UMLS concept ID', semantic type and match map list. Is RegEx the right tool or what is the most efficent way to accomplish this in Java?

  • php regex for strong password validation

    - by Jason
    Hello, I've seen around the web the following regex (?=^.{8,}$)((?=.*\d)|(?=.*\W+))(?![.\n])(?=.*[A-Z])(?=.*[a-z]).*$ which validates only if the string: * contain at least (1) upper case letter * contain at least (1) lower case letter * contain at least (1) number or special character * contain at least (8) characters in length I'd like to know how to convert this regex so that it checks the string to * contain at least (2) upper case letter * contain at least (2) lower case letter * contain at least (2) digits * contain at least (2) special character * contain at least (8) characters in length well if it contains at least 2 upper,lower,digits and special chars then I wouldn't need the 8 characters length. special characters include: `~!@#$%^&*()_-+=[]\|{};:'".,/<? thanks in advance.

    I'm trying to come up with a regex to be able to parse the following type of strings into groups. <link rel="alternate" type="application/rss+xml" title="[!PageTitle!]" href="[!SiteRoot!]/feed.xml" /> My regular expression is: \[\!(.+)\!\] The problem with this expression is that it seems to pull it all into 1 group: Found 1 match: "[!PageTitle!]" href="[!SiteRoot!]" has 1 group: 1. "PageTitle!]" href="[!SiteRoot" I want dont want the regex to continue...am I missing a boundary? Ideally I want it to find 2 groups, [!PageTitle!] and [!SiteRoot!]

  • Java RegEx Pattern not matching (works in .NET)

    - by CDSO1
    Below is an example that is producing an exception in Java (and not matching the input). Perhaps I misunderstood the JavaDoc, but it looks like it should work. Using the same pattern and input in C# will produce a match. import java.util.regex.Matcher; import java.util.regex.Pattern; public class Main { public static void main(String[] args) { String pattern = "aspx\\?uid=([^']*)"; Pattern p = Pattern.compile(pattern); Matcher m = p.matcher("id='page.aspx?uid=123'"); System.out.println(m.groupCount() > 0 ? m.group(1) : "No Matches"); } }

  • Match d-M-Y with javascript regex how?

    - by bakerjr
    Hi, my date formatting in PHP is d-M-Y and I'm trying to match the dates with a javascript regex: s.match(new RegExp(/^(\d{1,2})(\-)(\w{3})(\-)(\d{4})$/)) To be used with the jQuery plugin, tablesorter. The problem is it's not working and I'm wondering why not. I tried removing the dashes in my date() formatting (d M Y) and tried the ff and it worked: s.match(new RegExp(/^\d{1,2}[ ]\w{3}[ ]\d{4}$/)); My question is what is the correct regex if I'm using dashes on PHP's date() i.e. d-M-Y? Thanks!

  • regex to match postgresql bytea

    - by filiprem
    In PostgreSQL, there is a BLOB datatype called bytea. It's just an array of bytes. bytea literals are output in the following way: '\\037\\213\\010\\010\\005`Us\\000\\0001.fp3\'\\223\\222%' See PostgreSQL docs for full definition of the format. I'm trying to construct a Perl regular expression which will match any such string. It should also match standard ANSI SQL string literals, like 'Joe', 'Joe''s Mom', 'Fish Called ''Wendy''' It should also match backslash-escaped variant: 'Joe\'s Mom', . First aproach (shown below) works only for some bytea representations. s{ ' # Opening apostrophe (?: # Start group [^\\\'] # Anything but a backslash or an apostrophe | # or \\ . # Backslash and anything | # or \'\' # Double apostrophe )* # End of group ' # Closing apostrophe }{LITERAL_REPLACED}xgo; For other (longer ones, with many escaped apostrophes, Perl gives such warning: Complex regular subexpression recursion limit (32766) exceeded at ./sqa.pl line 33, < line 1. So I am looking for a better (but still regex-based) solution, it probably requires some regex alchemy (avoiding backreferences and all).

  • Regex to strip phpdoc multiline comment

    - by Reveller
    I have this: /** * @file * API for loading and interacting with modules. * More explaination here. * * @author Reveller <me@localhost> * @version 19:05 28-12-2008 */ I'm looking for a regex to strip all but the @token data, so the result would be: @file API for loading and interacting with modules. More explaination here. @author Reveller <me@localhost> @version 19:05 28-12-2008 I now have this: $text = preg_replace('/\r?\n *\* */', ' ', $text); It does the job partially: it only removes the * in front of each line. Who could help me so it also strips /** and the final slash /? Any help would be greatly appreciated! P.S: If, for instance, the commentlbock would contain something like /** * @foo Here's some slashes for ya: / and \ */ Then obviously the slashes after @foo may not be stripped. The reult would have to be: @foo Here's some slashes for ya: / and \ I hope there's a regex guru out there :-)

  • RegEx, matching if not containing...

    - by Tommy Jakobsen
    I've been trying to figure out how to write this regular expression. It is to be used for ISAPI_Rewrite, a module for IIS 6, for doing URL rewriting. I want the url /hg/<parameter> to be mathed, so it can be rewrited to /hg/hgwebdir.cgi/<parameter>. I've matched it using ^/hg/(.*). My problem is, if the URL /hg/hgwebdir.cgi/<parameter> is used, the regex should NOT match. Using the above regex with this URL, will rewrite to /hg/hgwebdig.cgi/hgwebdig.cgi/<parameter> which is not correct. Can you help me create the matching pattern?

  • Regex-expression with danish characters

    - by timkl
    I'm currently trying to wrap my head around regex, I have a validation snippet that tests an input box against a regex-expression: $.validator.addMethod("customerName", function(value, element){ return (/^[a-zA-Z]*$/).test(value); }, "Some text"); That works well, but when I try to add a space and some special danish characters, it doesn't filter the danish characters, only the space. $.validator.addMethod("customerName", function(value, element){ return (/^[a-zA-Z æøåÆØÅ]*$/).test(value); }, "Some text"); Any ideas to what could be wrong?

  • Checking if language is set in url with regex

    - by Saif Bechan
    I have am working on a multi language file. My urls look something like this: http://www.mydomain.com/en/about/info http://www.mydomain.com/nl/about/info Now I use a small regex script that redirect the user when they use a link without language. The script looks like this: preg_match('~^/[a-z]{2}/~', $_SERVER['REQUEST_URI'] This finds out is there is a language set en|nl|de etc. This works fine on all links except for these: http://www.mydomain.com/en http://www.mydomain.com/nl There is no trailing slash so the regex can not find the given values. Anyone know a fix for this?

  • Regex to validate SMTP Responses?

    - by Alix Axel
    I'm writing a regular expression that can interactively validate SMTP responses codes, once the SMTP dialog is completed it should pass the following regex (some parentheses added for better readability): ^(220)(250){3,}(354)(250)(221)$ Or with(out) authentication: ^(220)(250)((334){2}(235))?(250){2,}(354)(250)(221)$ I'm trying to do rewrite the above regexes so that I can interactively check if the dialog is going as expected, otherwise politely send a QUIT command and close the connection saving bandwidth and time, but I'm having a hard time writing an optimal regex. So far I've managed to come up with: ^(220(250(334(235(250(354(250(221)?)?)?){0,})?){0,2})?)?$ Which, besides only matching authenticated connections, has some bugs... For instance, it matches: 220250334235250354250221 220250334334235250354250221 I've also tried the following modification: ^(220(250)?)?((334(235)?){2})?(250(354(250(221)?)?)?){0,}$ This one accepts non-authenticated responses but it fails to match 220250334 and wrongly matches 220250334334235250354250221 (at least 2 250 are needed before the 354 response code). Can someone help me out with this? Thanks in advance.

  • Regex for url formatting (www.domain.tld to anchors)

    - by Kristaps
    Hi. I'm currently developing a little browser-based Twitter widget. Currently, I'm stuck with getting the URLs to work. I'm kinda newbie, when it comes to regex (I know, how to get parts of a string, but this one – tough one). So, I need a regex that would search/replace www.domain.tld -> <a href="http://www.domain.tld">http://www.domain.tld</a> With/without http://, preferably. Any advice is welcome. Thanks.

  • Regex find the first word

    - by Pez Cuckow
    I'm trying to use regex to add a span to the first word of content for a page, however the content contains HTML so I am trying to ensure just a word gets chosen. The content changes for every page. Current script is: preg_match('/(<(.*?)>)*/i',$page_content,$matches); $stripped = substr($page_content,strlen($matches[0])); preg_match('/\b[a-z]* \b/i',$stripped,$strippedmatch); echo substr($page_content, 0, strlen($matches[0])).'<span class="h1">'.$strippedmatch[0].'</span>'.substr($stripped, strlen($strippedmatch[0])); However if the $page_content is <p><span class="title">This is </span> my title!</p> Then my regex thinks the first word is "span" and adds the tags around that. Is there any way to fix this? (or a better way to do it).
