I heartily second that. Let me rave about the book! :-)

Some O'Reilly books are canonical on their subject, and some are fluff.

Its amazing to compare "Mastering Regular Expressions" with "Programming
Web Services with XML-RPC".

I picked the first up off a coworkers shelf out of curiousity, thinking
I knew regular expressions fairly well, and wondering how anybody could
possibly devote a whole book to it. It blew my mind. I haven't even come
close to reading and understanding it all, and I still learned how to do
things I didn't even know were possible.

The XML-RPC book, on the other hand, describes all of XML-RPC (the
protocol) in a single chapter, its that simple, and then consists of a
handful of sample apps in a few different languages.

All of which is fine, except it was about the same size and slightly
more expensive the the RegEx book! It should have been published in the
pocket reference format for half the price, and an eighth of the
physical weight. It has less info in it than the "Objective-C Pocket
Reference", which is a brilliant and concise little work.

Speaking of O'Reilly, they make a great Lex and Yacc book, or used to.
