Search Multiple Strings for Words from a Database?

I am working on a program that will search through news stories of an XML feed, and display a red overlay on stories that have negative-connotation words, blue on positive-connotation, purple on both, and grey if a string contains neither positive or negative words.

I was wondering the best way to implement searching through strings, I was a assuming an "if" statement would work best but I have gotten stuck in my programming. I'm somewhat of a newbie to processing, but I love to learn more!

I would appreciate any input, thanks!
