    I need to find a method in c++ to split a c++ string based on the occurence of a regular expression.

    In case that's confusing;

    My goal is to set up a vector <string> to recieve the value. the value is returned based on a regular expression. If the string were (quotes for clarity) "hello, world" this supposed method would return {"hello,","world"} if the regular expression given were a space.

    I've tried calling this supposed method (split) from the libraries string and regex.h by saying
    string str=txt.split(",")
    or something of that nature.

    anyone know of such a method?

    cstring's strtok() can do that, but your regular expression would have to be a single character. You'd just need to access the C-style string contained in your string object. If your needs get too specific, you could always write your own function

    The Boost libraries contain both simple string tokenizing and full-blown regular expression matching.
