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
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...
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...
