• Regex split string but keep separators

  - by rwwilden

  I'd like to do a Regex.Split on some separators but I'd like to keep the separators. To give an example of what I'm trying: "abc[s1]def[s2][s3]ghi" --> "abc", "[s1]", "def", "[s2]", "[s3]", "ghi" The regular expression I've come up with is new Regex("\\[|\\]|\\]\\["). However, this gives me the following: "abc[s1]def[s2][s3]ghi" --> "abc", "s1", "def", "s2", "", "s3", "ghi" The separators have disappeared (which makes sense given my regex). Is there a way to write the regex so that the separators themselves are preserved?

• linking to boost regex in gcc

  - by rboorgapally

  i am trying to compile my program which uses regex on linux. I built the boost library in the libs/regex/build by typing make -fgcc.mak which created a directory gcc which contains the following four files boost_regex-gcc-1_35 boost_regex-gcc-d-1_35 libboost_regex-gcc-1_35.a libboost_regex-gcc-d-1_35.a Now I want to use regex from my program which is in some arbitrary directory. I #included boost/regex.hpp I got the error which stated that regex.hpp is not found. Then I gave the -I option in the g++ compiler. I didn't get that error. But I get the following error undefined reference to `boost::re_detail::perl_matcher<__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<boost::sub_match<__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > >, boost::regex_traits<char, boost::cpp_regex_traits<char> > >::construct_init(boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > > const&, boost::regex_constants::_match_flags)' I googled and found that I need to somehow link one of the above 4 libraries to my program. How can I do it. Which one should I link and why?

• Very simple regex not working

  - by Thomas Wanner

  I have read that to match a word inside of a string using Regular expressions (in .NET), I can use the word boundary specifier (\b) within the regex. However, none of these calls result in any matches Regex.Match("INSERT INTO TEST(Col1,Col2) VALUES(@p1,@p2)", "\b@p1\b"); Regex.Match("INSERT INTO TEST(Col1,Col2) VALUES(@p1,@p2)", "\bINSERT\b"); Is there anything I am doing wrong ?

• Regex.Replace only replaces start of string

  - by Yannick Smits

  I'm trying to replace a friendly url pattern with a html url notation but due to lack of regex experience I can't figure out why my regex only replaces the first occurence of my pattern: string text = "[Hotel Des Terrasses \http://flash-hotel.fr/] and [Du Phare \http://www.activehotels.com/hotel/]"; text = Regex.Replace(text, @"\[(.+)\s*\\(.+)\]", "<a href=\"$2\" target=\"_blank\">$1</a>"); How can i make the second pattern be replaced with the HTML markup too?

• Regex, encoding, and characters that look a like

  - by hack.augusto

  First, a brief example, let's say I have this "/[0-9]{2}°/" regex and this text "24º". The text won't match, obviusly ... (?) really, it depends on the character encoding. Here is my problem, I do not have control on which chars the user uses, so, I need to cover all possibilities in the regex /[0-9]{2}[°º]/, or even better, assure that the text has only the chars I'm expecting °. But I can't just remove the unknow chars otherwise the regex won't work, I need to change it to the chars that looks like it and I'm expecting. I have done this through a little function that maps the "look like" to "what I expect" and change it, the problem is, I have not covered all possibilities, for example, today I found a new "-", now we got three of them, just like latex =D - -- --- ,cool , but the regex didn't work. Does anyone knows how I might solve this?

  Hello all, I have a WordPress blog with numerous URL's I wish to replace from this: http://www.oldwebsite.co.il/name/*.asp To this: http://www.newwebsite.com/?p=* For example, from this: http://oldwebsite.co.il/name/65971.asp To this: http://www.newwebsite.com/?p=65971 I believe the following plugin: http://urbangiraffe.com/plugins/search-regex/ will do the trick with regex, but I am looking for the correct regex to use here. I found this stackoverflow thread that has a similar task, but since I am not too apt with regex, I was hoping for help so I don't mess anything up. Thanks, Tal After searching stackoverflow, I found

• LookAhead Regex in .Net - unexpected result

  - by AaronM

  Hello, I am a bit puzzled with my Regex results (and still trying to get my head around the syntax). I have been using http://regexpal.com/ to test out my expression, and its works as intended there, however in C# its not as expected. Here is a test - an expression of the following: (?=<open>).*?(?=</open>) on an input string of: <open>Text 1 </open>Text 2 <open>Text 3 </open>Text 4 <open>Text 5 </open> I would expect a result back of <open>Text1 <open>Text 2 <open>Text 3... etc However when I do this in C# it only returns the first match of <open>Text1 How do I get all five 'results' back from the Regex? Regex exx = new Regex("(?=<open>).*?(?=</open>)", RegexOptions.IgnoreCase | RegexOptions.Singleline); string input = "<open>Text 1</open> Text 2 <open> Text 3 </open> Text 4 <open> Text 5 </open>"; string result = Regex.Match(input, exx.ToString(), exx.Options).ToString();

• Perl : get substring which matches regex error

  - by Michael Mao

  I am very new to Perl, so please bear with my simple question: Here is the sample output: Most successful agents in the Emarket climate are (in order of success): 1. agent10896761 ($-8008) 2. flightsandroomsonly ($-10102) 3. agent10479475hv ($-10663) Most successful agents in the Emarket climate are (in order of success): 1. agent10896761 ($-7142) 2. agent10479475hv ($-8982) 3. flightsandroomsonly ($-9124) I am interested only in agent names as well as their corresponding balances, so I am hoping to get the following output: agent10896761 -8008 flightsandroomsonly -10102 agent10479475hv -10663 agent10896761 -7142 agent10479475hv -8982 flightsandroomsonly -9124 For later processes. This is the code I've got so far: #!/usr/bin/perl -w open(MYINPUTFILE, $ARGV[0]); while(<MYINPUTFILE>) { my($line) = $_; chomp($line); # regex match test if($line =~ m/agent10479475/) { if($line =~ m/($-[0-9]+)/) { print "$1\n"; } } if($line =~ m/flightsandroomsonly/) { print "$line\n"; } } The second regex match has nothing wrong, 'cause that is printing out the whole line. However, for the first regex match, I've got some other output such like: $ ./compareResults.pl 3.txt 2. flightsandroomsonly ($-10102) 0479475 0479475 3. flightsandroomsonly ($-9124) 1. flightsandroomsonly ($-8053) 0479475 1. flightsandroomsonly ($-6126) 0479475 If I "escape" the braces like this if($line =~ m/\($-[0-9]+\)/) { print "$1\n"; } Then there is never a match for the first regex... So I'm stuck with a problem of making that particular regex work. Any hints for this? Many thanks in advance.

• Generating a list of values a regex COULD match in Python

  - by mlissner

  I'm trying to use a regex as an input, and from there generate all the possible values that the regex would match. So, for example, if the regex is "three-letter words starting with a, and ending in c," then the code would generate a list with the values [aac, abc, acc, adc, a1c....]. Is there an easy way to do this? I'm using python.

• regex substring C#

  - by sharma

  Hi, I need help to figure the regex expression I have string = "STATE changed from [Fixed] to [Closed], CLOSED DATE added [Fri Jan 14 09:32:19 MST 2011], NOTES changed from [CLOSED[]<br />] to [TEST CLOSED <br />]" I need to grab NOTES changed from [CLOSED[]<br />] to [TEST CLOSED <br />] and take values CLOSED[] and TEST CLOSED in two string variables. So far I got to: Regex NotesChanged = new Regex(@"NOTES changed from \[(\w*|\W*)\] to \[([\w-|\W-]*)\]"); which matches only if "NOTES changed from" started at the beginning and has no '[]' within '[ ]', but I have "[CLOSED[]]" and also no "". Any ideas on what to change in regex. Thanks, Sharma

• How to write this in different regex flavours

  - by taspeotis

  I have the following data: a b c d FROM:<uniquepattern1> e f g h TO:<uniquepattern2> i j k l FROM:<uniquepattern1> m n o p TO:<uniquepattern3> q r s t FROM:<uniquepattern4> u v w x TO:<uniquepattern5> I would like a regex query that can find the contents of TO: when FROM:<uniquepattern1> is encountered, so the results would be uniquepattern2 and uniquepattern3. I am hopeless with regex, I would appreciate any pointers on how to write this (lookahead parameters?) and any differences between regex on different platforms (eg the C# .NET Regex versus Grep vs Perl) that might be relevant here. Thank you.

• Regex: Use start of line/end of line signs (^ or $) in different context

  - by fgysin

  While doing some small regex task I came upon this problem. I have a string that is a list of tags that looks e.g like this: foo,bar,qux,garp,wobble,thud What I needed to do was to check if a certain tag, e.g. 'garp' was in this list. (What it finally matches is not really important, just if there is a match or not.) My first and a bit stupid try at this was to use the following regex: [^,]garp[,$] My idea was that before 'garp' there should either be the start of the line/string or a comma, after 'garp' there should be either a comma or the end of the line/string. Now, it is instantly obvious that this regex is wrong: Both ^ and $ change their behaviour in the context of the character class [ ]. What I finally came up with is the following: ^garp$|^garp,|,garp,|,garp$ This regex just handles the 4 cases one by one. (Tag at beginning of list, in the center, at the end, or as the only element of the list.) The last regex is somehow a bit ugly in my eyes and just for funs sake I'd like to make it a bit more elegant. Is there a way how the start of line/end of line characters (^ and $) can be used in the context of character classes?

• What's wrong with this regex (VBScript/Javascript flavor)

  - by OtherMichael

  I'm trying to run a regular expression in VBA code that uses Microsoft VBScript Regular Expressions 5.5 (should be the same as JavaScript regex) regex: ^[0-9A-Z]?[0-9A-Z]{3}[A-Z]?([0-9A-Z]{6})-?([0-9])?$ input: X123A1234567 match: 123456 the six characters I'm interested in give a good match of 123456, ignoring the last (check) digit. Perfect. (The check digit is captured, but it's not a major concern to me). But when BOTH the optional portions are gone (they are optional) the match grabs the last digit GOOD input: 123A1234567 match: 123456 Leave in the optional middle alpha, take out the optional leading alpha, and we still get the good match of 123456 GOOD input: X1231234567 match: 123456 Leave in the optional leading alpha, take out the middle optional alpha, and we still get a good match of 123456 BAD input: 1231234567 match: 234567 Take out BOTH optional alphas, and we get a bad match of 234567 Have a looksee @ the regex testers on http://www.regular-expressions.info/javascriptexample.html or http://www.regular-expressions.info/vbscriptexample.html What am I missing, here? How can I get the regex to ignore the last digit when both optional alphas are missing? The regex is used to feed a lookup system, so that no matter what format the input data, we can match to a complete value.

• Adding "Max Length" to Regex

  How can I extend already present Regex's with an attribute telling that the regex can't exceed a maximum length of (let's say) 255? I've got the following regex: ([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?) I've tried it like that, but failed: {.,255([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)}

• How to outperform this regex replacement?

  - by spender

  After considerable measurement, I have identified a hotspot in one of our windows services that I'd like to optimize. We are processing strings that may have multiple consecutive spaces in it, and we'd like to reduce to only single spaces. We use a static compiled regex for this task: private static readonly Regex regex_select_all_multiple_whitespace_chars = new Regex(@"\s+",RegexOptions.Compiled); and then use it as follows: var cleanString= regex_select_all_multiple_whitespace_chars.Replace(dirtyString.Trim(), " "); This line is being invoked several million times, and is proving to be fairly intensive. I've tried to write something better, but I'm stumped. Given the fairly modest processing requirements of the regex, surely there's something faster. Could unsafe processing with pointers speed things further?
