Is there a way to programmatically extract the feed of a podcast from the iTunes page?

Question

From an iTunes page, like http://itunes.apple.com/us/podcast/this-week-in-tech-mp3-edition/id73329404, is there a way to extract the corresponding feed address? In this case it would be http://leoville.tv/podcasts/twit.xml.

I know that if you open on iTunes you can extract it manually, but I want to do it programmatically. There's a link to the website of the podcast, but it may not be accurate. In this case it points to a web site with 20 podcasts on it.

A month later, but I just addressed this question over here. Hope it helps.
