Xsl transform of rss feed help please

greetings, Long time reader, First time writer!

My question is this;
I have a rss news feed up and running on a website, but I would like to sift through the 30-40 items provided and display only the ones with a certian word in the title.
For example in the following snippet of an rss feed I would like to display only the 2nd and 3rd items because they contain the word "Bush" in the title(sort of a regex type of search).

Any ideas on how to do this?

You can use the contains() string function to test to see if the
title contains what you're after. Something like:

Thanks, that is exactly what I was looking for.
