Later chapters (i.e., 4 through 9) look at more specific problems–e.g., performing validation on email addresses, ^^Which, validating an email address is not as easy as it sounds.^^^ dealing with Roman numerals, combing for text in the Apache Common Log Format, or parsing URLs. The recipes are all cross-referenced with each other, so if a particular solution really only solves about 75% of your problem, they’re prepared to point you in the right direction. They get right to the point, and then tell you where to go for more. What else can be said about these chapters except that they’re like the magnificent arsenal you’ll be wishing for when the text zombies swarm at your gate.
As I said before, if your work regularly brings you in contact with regular expressions, you’ll want to arm yourself with this. Highly recommended.
Disclosure: I received an electronic copy of this book from the publisher in exchange for writing this review.
UPDATE: (9/5/2012) I felt it was worth pointing out (as I did on Twitter):
@slevithan I tried to be more critical, I really did… 😉 (I hardly ever give out 5-star reviews)
