[Boost-users] Tokenizer Problem

Can anyone explain to me why the code below prints: Token: A1B21 Token: A1B Token: : Token: 12 Instead of printing: Token: A1B2 Token: : Token: 12 Token: A1B Token: : Token: 12 Using boost 1.31.0 Thanks! ---Cut here--- #include #include <iostream> int main() { boost::char_separator<char> sep("", ":", boost::keep_empty_tokens); boost::tokenizer< boost::char_separator<char> > stringTok(std::string("A1B2:12"),sep); boost::tokenizer< boost::char_separator<char> >::iterator tokIter=stringTok.begin(); while(tokIter!=stringTok.end()) { std::cout << "Token: " << (*tokIter) << "\n"; tokIter++; } boost::tokenizer< boost::char_separator<char> > stringTok2(std::string("A1B:12"),sep); boost::tokenizer< boost::char_separator<char> >::iterator tokIter2=stringTok2.begin(); while(tokIter2!=stringTok2.end()) { std::cout << "Token: " << (*tokIter2) << "\n"; tokIter2++; } } ---Cut Here--- -- Thomas Johnson
