Retrieve image from RSS feed in Quartz Composer

Im new to this application, and i am more or less just messing around with it in my spare time to see what i can come up with.
I am wondering if someone has experience with this program, and if anyone knows how to retrieve an image from an rss feed.
The basic source patch "rss downloader" takes in a URL and outputs information and article list', which i then have going into a standard macro patch that transmits the article into an output patch. This works fine for printing text from the feed, but for some reason i cannot go through the current page and single out the image for which i want to display on a 'billboard'.
I have experience creating an rss driven widget in javascript that takes the feed and parses through it searching for the link and image tags in the page, then outputs the image, but i cant figure out how to do this in quartz composer.

Does anybody know how to do this?
It would be awesome if someone could help me out, so i can finish this stupid side project im working on and get back to doing my actual term projects again haha.
