This was a talk given by me at WindyCityRails, its a combined talk with choices to do the basics or advanced. The audience chose the advanced side of the talk.

Regular Expressions help you find that needle in the haystack, where Waldo might be, or the location of Jimmy Hoffa’s body. You’ll find them in most programming languages and tools, but they can do so much more than checking an e-mail address! We’ll go over the basics as well as advanced topics and you’re encouraged to follow along as the examples are shown.
