Well, just get "Mastering Regular Expressions", by Jeffrey Friedl,
2nd edition -- it'll blow you away.

The title maybe should have been

        Everything you wanted to know about regular expressions,
               but were afraid to ask.

Plus a lot of stuff mayve you never did want to know, too.

On regexps, this book is THE BIBLE!

Next time in a bookstore and you spy one, have a look.

Ten to one you'll buy the thing.
