getting names subgroups
- by Abruzzo Forte e Gentile
Hi All
I am working with the new version of boost 1.42 and I want to use regex with named sub groups. Below an example.
std::string line("match this here FIELD=VALUE in the middle");
boost::regex rgx("FIELD=(?\\w+)", boost::regex::perl );
boost::smatch thisMatch;
boost::regex_searh( line, thisMatch, rgx );
Do you know how to get the content of the match ?
The traditional way is
std::string result( mtch["VAL"].first, mtch["VAL"].second );
but i don't want to use this way.
I want to use the name of the subgroups as usual in Perl and in regex in general.
I tried this, but it didn't work.
std::string result( mtch["VAL"].first, mtch["VAL"].second );
Do you know how to get the value using the name of the subgroup?
Thanks
AFG
