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
这是我最近读过些的最好的技术书籍了。原来正做表达式的用法可以这么神奇,虽然原来也一直是必备工具,但是从来没想到过怎么在整篇文章中直接用一个很简单的表达式找到连续重复的单词!想知道吗?去看看原著吧,就在第一章里面。

评分看正则的缘由: Vim用的有一短时间了, 时常用里面的替换功能,但有时发现简单替换仍旧力不从心,觉得应该看些正则的东西。 网上查了些正则的例子,但看过例子之后,只是觉得当前的东西可以用了,却始终抓不到边际本质。 暑假决定给自己放一周,平时的MRI的东西和Matlab,Pyth...
评分书是好书,如之前一人的评论,性价比很高。个人认为,如果你的日常工作经常涉及文本处理,那读本书应该能提升你的工作效率。 再谈翻译,虽然很多人说,本书翻译的质量不错,但实际上,翻译有很多错误,而且一些错误直接影响到文义,如要精读,还是应该辅以英文原文。
评分若论入门,《正则表达式必知必会》之类的书比这本书讲得简明易懂。若单说Perl的正则表达式,《Progamming Perl》比本书讲得权威。这本书涵括的语言包括Perl、Java、.NET、PHP,但是我相信很少有人同时用这几种语言编程的。我以为本书比较有价值的部分是第6章:打造高效的正则表...
很无聊的书,除非你每天都在和RE过不去,否则没有必要看
评分joyful reading~~~
评分#略显繁冗。不过Regular Expression也是必须掌握的玩意儿。This is the definitive book.
评分需要反复读
评分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。
