What everyone else said...

What more can I say besides what everyone else has said.
This is a WONDERFUL and POWERFUL book on Regular Expressions.

From just-beyond-beginner to advanced, this book provides a fantastic view into the world of Regular Expressions and the practical thinking involved with them. However, without at least a semi-understanding of the concepts you will not be able to get through the book very quickly.

I walked away with MUCH more knowledge than I had expected to. This applies to not only regular expressions, but also to rational thinking/planning when it comes to data and programmatic analysis.

Fantastic resource, don't go without it

This is must-have if you are trying to learn regexps or improve your knowledge of them. It carefully walks you through how to construct expressions, covering everything from the most basic tasks to complicated scenarios. It explains how matching works, so you can really understand what is going on behind the scenes.

Great Book!

This is a great book for learning about regular expressions. It goes into much detail, yet still remains an easy read for a novice who has not had much experience to RegEx. Recommended.

The ultimate book for the ultimate demands - For an introduction just too heavy weight

Jeffrey Friedl describes regular expressions at an amazing depth and precision. Regular expressions are not easy and the quirks of the different tools (including their exact version and for what operating system) make writing them to an irritating black art. A black art to almost anybody. MRE sorts everything out in a comprehensible fashion. The price the reader has to pay: a very dense book, a need to follow the details until your head starts swimming and a lot of strain on the memory about what works, how and where.

MRE is somewhat easier to comprehend for a reader with a strong Pearl background. Also a good prior understanding to regular expressions is a true asset here. If you have neither, you do not need to despair. Jeffrey Friedl explains everything thoroughly from the ground up.

The writing style is very pedagogical. Important things get repeated quite often. Still this book is very dense. The flow is dry: no rhythm, special sense of humor or wit sweetens your wading through the material. Nevertheless Jeffrey Friedl kept my interest through the pages though the reading felt like hard work.

I do recommend this book to the truly dedicated reader.

Excellent Resource

Regular Expressions need to be fully mastered in order to truly gain access to the power of many languages and programs. Whether you are working with Perl, PHP, Java, .NET, Ruby, C, Python or any of a variety of other languages the use of regular expressions allows you to work with your data in powerful ways. As a general rule most books that even mention regular expressions just mention a very few of the common ways to build an expression. This book takes the reader well beyond that level and explores the many more unusual ways regular expressions can be used. If you don't know what a regular expression is then you have no need for this book, but if you have ever worked with regular expressions then you are in for a treat with this book. I have used them for years and built a whole spam filter system around regular expressions but there is so much more they can do and this book can make you an expert.

After a basic introduction covering the most common tasks regular expressions are used for (substitution, selection, wild cards, etc.) the author delves into examples of regular expressions in Perl, and follows that with a section discussing some of the variations in regular expressions as implemented in different languages and common programs. One of the most important features of the book is the plethora of real world programming examples. Mastering Regular Expressions is highly recommended to anyone who wants to completely master the full art of regular expressions.
