I just bought the book today and I have already finished reading it. The information in this book is outstanding, especially if you are new to regular expressions. I recommend this book to anyone that wants to learn an efficient way to preform string validation.
I got this book 2 days ago. It is great. I'm only to chapter 3 but it is making everything clear to me finally! Normally I don't have time to read up on things like regex because of workload, but this info has already saved me time at work! Also, the appendix with the real world regex's is a great time saver. I recommend it to everyone.
I started reading this and immediately got hit with the fact that the "results" for each query were incorrect (shows the same data as the "text" field) on my Nook Tablet. So I downloaded the Nook PC application and viewed the book, and you can see where the text is shaded grey with the "results" field, showing the proper output if a query were run. That said, I wouldn't buy this for the Nook, unless there is some trick to making it work that I don't know about. I'm only on page 50, but I like the flow of the book so far.
