Learning Regular Expressions

by Ben Forta

Learn to use one of the most powerful text processing and manipulation tools available Regular expression experts have long been armed with an incredibly powerful tool, one that can be used to perform all sorts of sophisticated text processing and manipulation in just about every language and on every platform. That’s the good news. The bad news is that for too long, regular expressions have been the exclusive property of only the most tech savvy. Until now. Ben Forta's Learning Regular Expressions teaches you the regular expressions that you really need to know, starting with simple text matches and working up to more complex topics, including the use of backreferences, conditional evaluation, and look-ahead processing. You’ll learn what you can use, and you’ll learn it methodically, systematically, and simply. Regular expressions are nowhere near as complex as they appear to be at first glance. All it takes is a clear understanding of the problem being solved and how to leverage regular expressions to solve them.

that's a wonderful book. i read it in 2-3 days from cover to cover (expect the appendix A). the book consists of 10 lessons on various aspects of regex with lots of examples and tips. almost every thing told in this book is showed by a problem (comes in plain text), a regex pattern and the result extracted from problem. i should also mentions that there's an extra lesson, which is about usages of regex in real world problems. the appendix covers regex implementations on different programming languages.

This is probably the best technical book I've read in terms of readability. I was easily able to keep myself focused and follow along with the text. The only downside was that I found a couple of mistakes and I found his unanswered questions frustrating. I figured I paid enough money for him to answer all the questions, haha!
