Regular expressions are an extremely powerful tool for manipulating text and data. They are now standard features in a wide range of languages and popular tools, including Perl, Python, Ruby, Java, VB.NET and C# (and any language using the .NET Framework), PHP, and MySQL.
If you don't use regular expressions yet, you will discover in this book a whole new world of mastery over your data. If you already use them, you'll appreciate this book's unprecedented detail and breadth of coverage. If you think you know all you need to know about regular expressions, this book is a stunning eye-opener.
As this book shows, a command of regular expressions is an invaluable skill. Regular expressions allow you to code complex and subtle text processing that you never imagined could be automated. Regular expressions can save you time and aggravation. They can be used to craft elegant solutions to a wide range of problems. Once you've mastered regular expressions, they'll become an invaluable part of your toolkit. You will wonder how you ever got by without them.
Yet despite their wide availability, flexibility, and unparalleled power, regular expressions are frequently underutilized. Yet what is power in the hands of an expert can be fraught with peril for the unwary. Mastering Regular Expressions will help you navigate the minefield to becoming an expert and help you optimize your use of regular expressions.
Mastering Regular Expressions, Third Edition, now includes a full chapter devoted to PHP and its powerful and expressive suite of regular expression functions, in addition to enhanced PHP coverage in the central "core" chapters. Furthermore, this edition has been updated throughout to reflect advances in other languages, including expanded in-depth coverage of Sun's java.util.regex package, which has emerged as the standard Java regex implementation. Topics include:
A comparison of features among different versions of many languages and tools
How the regular expression engine works
Optimization (major savings available here!)
Matching just what you want, but not what you don't want
Sections and chapters on individual languages
Written in the lucid, entertaining tone that makes a complex, dry topic become crystal-clear to programmers, and sprinkled with solutions to complex real-world problems, Mastering Regular Expressions, Third Edition offers a wealth information that you can put to immediate use.
Reviews of this new edition and the second edition:
"There isn't a better (or more useful) book available on regular expressions."
--Zak Greant, Managing Director, eZ Systems
"A real tour-de-force of a book which not only covers the mechanics of regexes in extraordinary detail but also talks about efficiency and the use of regexes in Perl, Java, and .NET...If you use regular expressions as part of your professional work (even if you already have a good book on whatever language you're programming in) I would strongly recommend this book to you."
--Dr. Chris Brown, Linux Format
"The author does an outstanding job leading the reader from regex novice to master. The book is extremely easy to read and chock full of useful and relevant examples...Regular expressions are valuable tools that every developer should have in their toolbox. Mastering Regular Expressions is the definitive guide to the subject, and an outstanding resource that belongs on every programmer's bookshelf. Ten out of Ten Horseshoes."
--Jason Menard, Java Ranch
这本书讲了不少关于正则表达式引擎的东西,并且花费了很大力气讲解基于回溯的NFA引擎。好像回溯是实现正则引擎的唯一算法。 事实上,有很多更高效的算法,我自己就实现过一个正则引擎,专门针对正则表达式集合的匹配,也就是说,给定很多个正则表达式(比如100万个),对输入...
评分书比我想象中的厚,当初选择看这本书完全是被电子书的大小给骗了,网上流传的epub格式的电子书虽然1M不到,本还打算当做厕所读物看的,结果没想到这本书看了这么久,久到我刷完了《good luck charlie》四季,这本书还在坚挺着摆在我的书桌上。另外在这里提一句,千万别把网上流...
评分首先术语翻译不佳,扣掉一星。例如atomic grouping翻译为“固化分组”,就是“原子分组”吗。其他“匹配优先”就是”贪婪“匹配吗,还有一些别的,看的很不顺畅。 其次,原文介绍了正则表达式的应用和使用技巧以及回溯等原理性介绍,但是没有介绍code是如何实现的,因此有些地...
评分正则表达式非常强大,在各种语言都有相关的包或库。看完了前五章已经对我大有帮助!翻译也不错,读起来顺畅,内容包括了从入门到精通,后面几章主要是分语言来讲解正则的应用,有Perl、Java、.NET和PHP,可以选自己掌握的语言来看。本人认为是程序员必读的一本工具书。

以前不会用正则的日子是怎么过来的?一晚上通宵读完,收获实在是太大了。这绝对是最最最立竿见影的学习项目了。
评分前面不错,可惜不是js专用的
评分跳过大段废话是相当不健康的读法。
评分作爲教材,這書基本勝任了它的職能,而且比那個老師講得明白得多。
评分好书,写的很清楚,很快就把regular expression差不多可以写出来了。
