Media praise for Regular Expressions Cookbook

"This is a well-researched book, full of information, from which I learned a number of new tricks just by reading the introductory chapter. Presenting the same tasks solved in different programming languages is valuable because it exposes important differences in how the different languages treat the "same" regular expression. Beginners as well as experienced users of regular expressions will find this book useful. "
-- Nikolaj Lindberg, Computational Linguist, STTS Speech Technology Services

"The Regular Expression Cookbook provides elegant solutions for immediate problems while building a strong understanding of the solution used. Overall, I am stunned at the attention to detail in the recipes. I've reviewed a good number of programming books and very few are as well-researched or thorough. "
-- Zak Greant, open technology advocate and strategist

"This book is really made for a person like me. The structure is problem-solution based. And, every problem is numbered in outline format. Thus, referencing back is an easy affair...This is a good, useful book. It's helping me to become a better engineer. "
-- Bob Reselman,

"We have been waiting for this one... This book does better than that by collecting hundreds of examples together in ways that build your understanding while never getting abstract or divorced from the real problems we face. Your shelf has a place for this book. Recommended. "
-- Brett Merkey,

"What I love about this book is two things: It’s filled with practical, real world examples of RegEx...It covers all the common gotchas that you inevitably run into when you start building non-trivial regular expressions...Regular Expressions Cookbook manages to be simultaneously accessible and almost ridiculously comprehensive. I consider myself a fairly advanced regex user and about 50 pages in I’ve already had three big “oh, wow, I didn’t realize that” moments. In my mind, at least, this completely replaces the Friedl book as the go-to reference for programmers of any skill level or background who seek regular expression enlightenment. "
-- Jeff Atwood, Coding Horror Blog

"This most excellent book shows you everything you need to know about regular expressions, and then some, regardless of whether you are a programmer. More importantly, if you read this book cover to cover, you'll become a world class chef of regular expressions. "
-- John Vacca,

"Overall, I’m very satisfied with Regular Expressions Cookbook, and recommend it to everyone just learning or brushing up on their regular expression skills. Armed with this book, and some of the software tools mentioned in Chapter 1, you’ll be ready to tackle an upcoming programming assignment using a Regular Expression or two."
-- Tony Cappellini, BayPIGgies

"This O'Reilly Cookbook is everything it promises and more. It provides a comprehensive and easy to follow cookbook for one of the most valuable tools in any programmer's arsenal...This is an extremely necessary book for any programmer's library. "
-- Ira Laefsky,

"I hate to cave in to the consensus of reviews on the web, but this book is hot!...Bottom line, I'd have to say that the Regular Expressions Cookbook is best used by someone who doesn't use regular expressions regularly (sorry), but whose work efficiency would be enhanced by using a regex engine. I'd have to say that authors Goyvaerts and Levithan and O'Reilly have hit a home run with this book. "
-- James Pyles, Million Chimpanzees

"Very well written and I would like it to be part of your library, if it is not already there."
-- Vikas Shukla, Reference Designer

"...a good addition to any programmers bookshelf. It is well written and concise and has lots of very useful receipes - such as URL/Paths/Addresses manipulators (getting host, frame, email address etc), and some very useful ones for specific formats, such as date formats, phones numbers, zip and UK postocdes. What's really impressive is the book provides useful links to reference materials (RFCs, Telecoms standards, British and ISO standards). "
-- Philip, Figment Engine

"Just from what I’ve read so far and scanned from later in the book, this looks like it will be THE book on regular expressions. I made a huge leap forward with the O’Reilly Mastering Regular Expressions book, but this one looks like it will make an even bigger impact for regex users. This book is just so well-written and thought out. Even though you guys are explaining a complex subject, everything feels very straightforward and easy to grasp. The tutorial is excellent, and the cookbook part is great for showing examples with common regex uses. Thanks for writing this book!"
-- Cory Hudson, Flagrant Badassery

" awesome book. Not only does it contain a huge number of "recipes" for using regular expressions to solve real world problems, it has a thorough and easy-to-follow tutorial on what regular expressions are and how they work. Even if you are someone who feels very comfortable with regular expressions, I would highly recommend reading the tutorial - you will definitely learn things that you didn't know before. I certainly found myself dog-earing some new tip every few pages... I highly recommend this book for anyone who wants to get into regular expressions for the first time or for anyone who wants to take their existing regular expression skills to the next level."
-- Ben Nadel, The Blog of Ben Nadel

"After buying the 3rd edition of Mastering Regular Expressions by Jeffrey Friedl about 2 and a half years ago I thought I would never read another book about Regular Expressions again. That was until I saw Jeff Atwood’s review of Regular Expressions Cookbook by Jan Goyvaerts and Steven Levithan. Now I have been known in the past to buy and read a book based on the suggestion of Jeff Atwood so who was I to say no this time...This book will be a useful reference for some time to come."
-- Martin Jagger, Martin C# and .NET Fanboy!

"...a book for the true geek to curl up with and read. You may not need the information now, but you will need it someday and just browsing is an effective way to pick it up. Likewise, if you're looking for an immediate solution to a problem right now, just check the Table Of Contents...In short, this is the newest benchmark reference for Regular Expressions. With this and Mastering Regular Expressions, you are going to be a Master of the Universe and do things with text that will leave ordinary mortals awestruck. "
-- Jerry Saperstein,

"...Regular Expressions Cookbook is a useful addition to a programmer's reference shelf."
-- Sharon Machlis, Computerworld Blogs

"This is hands-down the best book on the regular expression written by the Reg-Ex guru Jan Goyvaerts himself. Sysadmins and DBAs who write administrative scripts in Perl should definitely have this book as a reference. This is a must-have for programmers of all languages. When you have this book in your desk, regular expression will not look intimidating at all."
-- Ramesh Natarajan, The Geek Stuff

"Overall the book is useful if you want to either extend your knowledge of regular expression or really do need help with a specific problem...If what you really want is a cookbook then this is as good as it gets."
-- Ian Elliot, iProgrammer

"I love the O'Reilly Cookbook series. The format is very usable, and very helpful. This book continues the trend. This book fully met my expectations, giving me easy access to syntax for common Regular expression problems I need to solve. The recipes are all practical, but solve a range of simple to complex problems. I will keep this book close by and use it often, it is a great reference tool! "
-- Jeremy P. Petersen,

"What I was looking for was a book that would teach regular expressions while giving concrete examples of real life use cases that I could immediately put to work. This book is filled with them...The best part of the book is that every example uses a clear format that sets the stage for an easy discovery of needed information...This book will be used regularly as a reference."
-- Matthew Helmke,

"Like many other "cookbooks" offered by O'Reilly, Regular Expressions Cookbook is proving to be an indispensable companion..."
