I take it that browscap[0] does it not do what you want?
I have an generator at [1].
Feel free to steal.

Also once you do get yours working, you'll want to use ctRegex and 
generate a file with all of them in it. That'll increase performance 
significantly.

Reguarding regex, if you want a named sub part use:
(?<text>[a-z]*)
Where [a-z]* is just an example.

I would recommend you learning how input ranges work. They are used with 
how to get the matches out, e.g.

auto rgx = ctRegex!`([a-z])[123]`;
foreach(match; rgx.matchAll("b3")) {
     writeln(match.hit);
}

Or something along those lines, I did it off the top of my head.
