Regular expressions, unless you’re a mathematician or a computer scientist, are fairly irregular things. What started as ways to write patterns to match strings of characters has grown out of control, especially with regexes (as they’re called) being a fundamental part of the Perl programming language.

Friedl presents here the most comprehensive covering of regexes that can possibly be put in bound book form. The first six chapters will give you everything you need to learn and hopefully understand regexes, while the latter chapters give you insight into language/framework-specific implementations of them (including Perl, Java, PHP and .NET).

Having dealt with regexes a lot in the past, this book did not wow or amaze me. It did, however, provide some useful tips for future regex writing. If you’re a regex newb, it would be greatly useful, especially if you’re planning on writing a lot of regexes. If you’re a seasoned veteran, it may be beneficial to skim this book, but by no means skip it, unless your name happens to be Jeffrey Friedl.

My only complaint with this book is that most of the .NET examples are in the abomination of a “programming language” called Visual Basic. Why such a language even still exists in beyond me. However, since VB is part of .NET, most of the examples can be trivially translated into more meaningful languages, such as C#.

I would highly recommend this book for anybody who dedicates any reasonable amount of time towards constructing regular expressions, as well as to anybody who spends an inordinate amount of time writing methods/functions/subroutines to handle complex (that is, more than “this string equals this string”) string matching. Regular expressions will save you countless hours, since somebody’s done all that heavy lifting for you already! ( )

Essential, although mind-bending.

Book description
Haiku summary

Amazon.com Amazon.com Review (ISBN 0596528124, Paperback)

Regular expressions are a central element of UNIX utilities like egrep and programming languages such as Perl. But whether you're a UNIX user or not, you can benefit from a better understanding of regular expressions since they work with applications ranging from validating data-entry fields to manipulating information in multimegabyte text files. Mastering Regular Expressions quickly covers the basics of regular-expression syntax, then delves into the mechanics of expression-processing, common pitfalls, performance issues, and implementation-specific differences. Written in an engaging style and sprinkled with solutions to complex real-world problems, Mastering Regular Expressions offers a wealth information that you can put to immediate use.

Introduces regular expressions and how they are used, discussing topics including metacharacters, nomenclature, matching and modifying text, expression processing, benchmarking, optimizations, and loops.
