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.
