A regular expression (regex for short) is a powerful language to describe a search pattern to analyze and modify text. Initially used in Unix text processing utilities ed and grep, many programming languages now have built-in support for regular expressions, such as Perl, Ruby, AWK, and Tcl. Others support it via a standard library, such as .NET languages, Java, Python and C++. This talk assumes you dabbled with regular expressions before, and teaches you how to read, construct and use simple to complex regular expressions. At the end of the session you'll understand how to define a regex that validates an e-mail address: \b\w[\w.%+-]?@[\w.-]+\.[a-zA-Z]{2,6}\b
