Mastering Regular Expressions

A regular expression (regex) is a pattern that describes a set of strings. Regular expressions are used for advanced context-sensitive searches (e.g. parsing data streams, data mining) and text modifications. They can be found in many advanced editors (e.g. vi, Emacs), in parser programs (e.g. grep) and in languages (e.g. Perl), mostly in a UNIX environment. This book is the standard work on regexes.Friedl, Jeffrey is the author of 'Mastering Regular Expressions', published 2006 under ISBN 9780596528126 and ISBN 0596528124.
