Having erroneously asked this in another thread, I am starting it anew in this one.

The subject of Mid() came up, and after chasing it down, I understand how to use it and Left() to do some stuff.

What I'm really after is a fully realized regular expression engine that can let me specify much less rigid structures. Perl, vi, various *nix shells all have them, but I can't find a good reference to them for Excel VBA. Rumor (in the form of shg) has it that what I seek is out there. So... any guidance?

Thanks!
