I find in many of my classes that programmers have overlooked the use of Regular Expressions. Sometimes called Pattern Matching, RegEx is used to find particular patterns. It is great to use in form validation but it can also be used for much more.
It is supported in many languages including JavaScript, ColdFusion, Java and many more (including the Find and Replace feature in Dreamweaver!).
Use the RegEx Tester and see some sample Regular Expressions at the Regular Expression Library.
