Dear Boost programers: I copied a piece simple Using Regular Expressions to Split a String code from book(c++ cookbook) chapter 4 section 24, page 196-197, Example code 4.33 --------------------------------------------------------------------- // Example 4-33. Using Boost's regular expressions #include <iostream> #include <string> #include <boost/regex.hpp> int main() { std::string s= "who,lives:in-a,pineapple under the sea?"; boost::regex re(",|:|-|\\s+"); // Create the reg exp boost::sregex_token_iterator // Create an iterator using a p(s.begin(), s.end(), re, -1); // sequence and that reg exp boost::sregex_token_iterator end; // Crate an end_of_reg_exp // marker while (p != end) std::cout << *p++ << '\n'; } ------------------------ source code http://examples.oreilly.com/9780596007614/
