Quick question about the Boost::Regex library. Is there a way to identify, with sub-matches, where a match in the search string is made and the length of the match? For instance, with the following regular expression and search string:
Regex ==> "(\d+)" Search String ==> "Give me 100 dollars or give me 2001 dollars."
Is there a way to determine that the subexpression matched at positions 8 and 31 in the search string, and that the lengths of the matches were three and four characters?
Take a look at the position(sub) and length(sub) member functions of match_results<> sub_match also has a length() member function, but no position() because it doesn't know where the search started from (unlike match_results which does). There's no need to get involved with repeated captures and match_extra etc BTW. John.
