How do I tokenize a string in C++?

I have a string "this is a string", and I want to iterate over all the words in this string. Is there a way in which i can easily do this without having to parse it.

Thanks

void do_something(const std::string& word);

std::for_each( std::istream_iterator<std::string>(is)
             , std::istream_iterator<std::string>()
             , do_something );
