Re: [Boost-users] Regex Submatch Position Question

<snip>

...

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? </snip>

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.

Thank you, I think that's exactly what I need. Appreciate it!
