A simple and easy to follow introduction to Regular Expressions.
According to Wikipedia, a regular expression (abbreviated regex or regexp) is a sequence of text characters, some of which are understood to be metacharacters with symbolic meaning, and some of which have their literal meaning, that together can automatically identify textual material of a given pattern, or process a number of instances of it that can vary from a precise equality to a very general similarity of the pattern.
However you want to describe them, they are the bane of most programmer's lives. In this short video, Thom gives a simple and easy to follow introduction to the topic.
