"I don't know anybody who's made a record that sounds decent in the past 20 years, really" -- Bob Dylan, 2006

I've corresponded personally with Jeffrey Friedl several
times over the last few years, and I remember being at once impressed with his attention to detail and his focus. I was invited to be one of the technical review editors for this third edition of his authoritative book on Regular Expressions, but had to pass due to time constraints.
However, I am pleased to state that whoever the tech reviewers were, they did a thorough job on this one from O'Reilly.
This book has matured over these three editions to become what I would consider the most detailed and valuable book about Regex on the planet - and that means whatever your favorite programming language or platform is. |
You see, Regular Expressions is in itself a language, and transcends programming languages and platforms because the concepts are basically the same across all languages - whether it be Perl, JAVA, C#, Visual Basic, Javascript, PHP, Ruby, Python, TCL - you name it.
And this book focuses on the mastery
of regex, not being a reference tool. Though each language has a different syntax for handling objects and methods, the underlying objects and methods are the same with Regex, so even complex examples shown in one language directly translate to the other languages.
I am not going to bore you by reproducing the books Table of Contents, you can view all this on the O'Reilly site here. Suffice to say that there are basic concept chapters that are really language - agnostic, and then specific sections on PHP, .NET, JAVA, and Perl. The book covers practical Regex techniques and most importantly, it gets you to the conceptual level where you can begin constructing Regex patterns on your own, without having to look for "examples".
For .NET developers, Jeffrey provides a complete table-based overview of .NET's Regular Expression flavor, with a focus on the new features available in .NET 2.0, including class subtraction, RegexOptions, and named capture.
In sum, let me just say that any developer who finds the need to manipulate text - whether it be scraping a web page, creating a report, importing data, or a hundred other applications, is going to need Regular Expressions. Jeffrey's book provides a complete and mature approach that is fresh, timely and detailed. I would recommend this book for any developer.
This book is approximately 500 pages, including index, and the sticker price is $44.99. Of course, the book can be obtained at various booksellers in stores or online at discounted prices. Highly recommended!
