Regular expressions are an extremely powerful tool for manipulating text and data. They have spread like wildfire in recent years, now offered as standard features in Perl, Java, VB.NET and C# (and any language using the .NET Framework), PHP, Python, Ruby, Tcl, MySQL, <em>awk</em>, Emacs, and many other popular tools and languages. 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. In spite their wide availability, flexibility, and unparalleled power, regular expressions are frequently underutilized. 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. A command of regular expressions is an invaluable skill. 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. 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. Mastering Regular Expressions, Second Edition has been thoroughly updated to include all the new features of Perl 5.8, as well as several other languages, including Java, VB.NET, C#, Python, JavaScript, Tcl, and Ruby. Written in the lucid, entertaining tone that made a complex, dry topic crystal-clear to thousands of programmers, and sprinkled with solutions to complex real-world problems, Mastering Regular Expressions offers a wealth information that you can put to immediate use. Topics include:

<li type="disc">A comparison of features among different versions of many languages and tools <li type="disc">How the regular expression engine works <li type="disc">Optimization (major savings available here!) <li type="disc">Matching just what you want, but not what you don't want <li type="disc">Sections and chapters on individual languages

虽说看过manual，几个例子，每个人都可以开始写regex了 但是磨刀不误砍柴工，还是把原理搞清楚，以后可以省去你调试的大量时间，最重要的是你可以在那些只知道basic的菜鸟面前显摆NFA,DFA,POSIX NFA，驱动，回溯的道理 里面有一个词汇翻译的特别不好greedy ，有限匹配，贪婪...  

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...  

佩服作者，真的是很厉害，佩服他对各种语言的了解和掌握。 正则表达式对于很多我遇到的新手或者高手都是他们的一个瓶颈，有很多人不了解或者不是很了解正则表达式，其实如果不是之前的工作逼迫我也不会接触它，但是真的上手以后发现，正则真是一个好东西，简洁优美。 但是查询...

用户评价

虽然只看了前面几章，但是已经深深体会到regex的博大精深！
