Hi ! I work with Visual Studio 2003, C++. I am reading data from a UNICODE file in a std::wstring. (It works fine) I want to find with boost::regex_search a pattern like the following: @@FOREACH(item in list) data @@END I want 3 substrings (submatch) like the following: 1- item 2- list 3- data We can have line feed, carriage return, space, etc. between ( and item, between ) and the data, and between data and @@END. So the following must work: @@FOREACH( item in list ) data @@END I DID MANY THINGS (TRY AND ERROR) AND I CAN FIND the first submatch item and the second submatch list. The third submatch never works. It don't see the @@END command (instruction) and get all the remaining stuff of the string. I used Regex Coach software and Rad Regex Designer but with theses softwares, my REGEX expression works. What is the correct REGEX expression with BOOST ???? Thank you ! :-( -- View this message in context: http://www.nabble.com/Need-help-with-REGEX-expression-%28-boost%3A%3Aregex_s...
