tokens!!

[Neo Nemesis]

How would I break this up into tokens?

#include <iostream>
#include <cstdlib>
#include <fstream>

using namespace std;

int main ()
{   
       ifstream ifs("config.ini",fstream::in);
       string str; size_t found;
       while (ifs >> str) {
          found=str.find('=');
          if (found!=string::npos) {
             string a; 
             string b;
             a = str.substr(0,found);
             b = str.substr(found+1);
             if (a == "ALMNT") {
                //b contains a,string,of,tokens like that
                ....tokens??
             }
             else { 
                 //...other commands 
             }
          }
       }
       ifclose();
}

How would I got about taking string "b" and breaking it up into tokens?

From the reading I've done strtok() only works with char :\
