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. --This text refers to an out of print or unavailable edition of this title.

Product Description
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, awk, 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:

  • 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
