Regular Expressions - Help!!!

If you are like me you find dealing with regular expressions both powerful and frustrating.I found a couple links that may help you on your journey to build regular expressions.

Roy Osherove has a few tools here that will be useful. The first is the Regulator that allows you to build regular expression with intellisense included. The second tool is the regulazy that allows you to typein text select it and via right click create your regular expression:

Setting User Control Properties in a Repeater

The way microsoft parses this is kind of silly but you need to ensure that you use a single quote to wrap your property values. You CANNOT place any text between the ' and < % or it will fail.
