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, andto 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.
About This Book
This book starts with a general introduction to regular
expressions. The first section describes and defines the
constructs used in regular expressions, and establishes the

tions of the book are devoted to the syntax, features, and
usage of regular expressions in various implementations.
Theimplementations coveredinthisbookarePerl,Java™,
.NET and C#, Ruby, Python, PCRE, PHP, Apache web
server,vi editor, JavaScript, and shell tools.
