Regexp Mini-Tutorial: Character Classes,,

30 minutes



Character classes form their own mini-language inside the regular
expressions (which are a mini-language inside Perl). In recent
versions of Perl, an algebra was added to this language.

In this talk, we'll discuss character classes; we'll show how to
use them; how to make them work for you. And in particular, we'll
show how you can use existing classes to create new ones.
