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.

We’ll go over the basics as well as advanced topics and you’re encouraged to follow along as the examples are shown.
