Regular Expression Pocket Reference 2nd Revised edition

A guide to the syntax and semantics of regular expressions for Perl 5.8, Ruby, Java, PHP, C#, .NET, Python, JavaScript, and PCRE.
Regular expressions arc a language used for parsing and manipulating text. They are often used to perform complex search-and-replace operations, and to validate that text data is well-formed.Today, regular expressions are included in most programming languages, as well as in many scripting languages, editors, applications, databases, and command-line tools. This book aims to give quick access to the syntax and pattern-marching operations of the most popular of these languages so that you can apply your regular-expression knowledge in any environment.
Concise and easy to use, this handy guide offers programmers a complete overview of the syntax and semantics of regular expressions, which are at the heart of every text-processing application.
This handy little book offers programmers a complete overview of the syntax and semantics of regular expressions that are at the heart of every text-processing application. Ideal as a quick reference, Regular Expression Pocket Reference covers the regular expression APIs for Perl 5.8, Ruby (including some upcoming 1.9 features), Java, PHP, .NET and C#, Python, vi, JavaScript, and the PCRE regular expression libraries.This concise and easy-to-use reference puts a very powerful tool for manipulating text and data right at your fingertips. Composed of a mixture of symbols and text, regular expressions can be an outlet for creativity, for brilliant programming, and for the elegant solution. Regular Expression Pocket Reference offers an introduction to regular expressions, pattern matching, metacharacters, modes and constructs, and then provides separate sections for each of the language APIs, with complete regex listings including:Supported metacharacters for each language APIRegular expression classes and interfaces for Ruby, Java, .NET, and C#Regular expression operators for Perl 5.8Regular expression module objects and functions for PythonPattern-matching functions for PHP and the vi editorPattern-matching methods and objects for JavaScriptUnicode Support for each of the languagesWith plenty of examples and other resources, Regular Expression Pocket Reference summarizes the complex rules for performing this critical text-processing function, and presents this often-confusing topic in a friendly and well-organized format. This guide makes an ideal on-the-job companion.
