Regular Expression Pocket Reference
Regular expressions are 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 program- ming 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-matching operations of the most popular of these languages so that you can apply your regular-expression knowledge in any environment.
The second edition of this book adds sections on Ruby and Apache web server, common regular expressions, and also updates existing languages.
