I’ve always been a fan of the ‘Cookbook’ series of books: it’s the information I want, when I want it, without the fluff. This book definitely does not disappoint. Here’s how the book is laid out:
1. Present the problem.
2. Present the solution
3. Present the solution if it’s different in .net, java, pcre, etc.
While the earlier chapters deal with the basics and some theory, this book is geared more to regex veterans. Regardless, it’s a great addition to my ‘essentials’ shelf. Highly recommend to any professional who deals in regular expressions daily.
