Scripting Question

I have setup and successfully ran scripts using a private instance. One thing I am not able to figure out with scripts is how to test if a text string appears in a HTML page. Anyone have an idea on how I would go about doing this?

No good way to do content validation right now. It’s open as a high-priority issue for me to implement: http://code.google.com/p/webpagetest/issues/detail?id=109 (though probably measured in months before it is done).
