        I'd have thought that

        regex / string

should yield an iterator into the match groups container:

        for(g = regex / string;  g++; g) {
                cout << "group = " << *g << endl;
        }

and hence

        if(regex/string)...

works because it yields a 'null' iterator if the comparison fails.
To substitute the groups into the format string:

        (regex/string) >> format

to reference group 3:

        (regex/string)[3]

Another possibility is just:

        m = regex/string;
        for (g = m.begin(); g++; m.end()) ..

ie. regex/string is a standard container supporting
random iterators.
