I have a question regarding boost::regex.
I have one regex which should identify my string AND cut it into pieces. I've tried with regex_token_iterator and cmatch and failed.
How about (caution, untested, off the top of my head!): #include <string> #include <iostream> #include <boost/regex.hpp> int main() { std::string s("s0,s1,s2"); boost::regex re("\\s*(s[0-9])\\s*(?:,\\s*)?"); // 1. attempt boost::sregex_token_iterator i(s.begin(), s.end(), re, 1), j; while(i!=j) { std::cout << *i++ << std::endl; } } HTH, John.
