[colug-432] Podcast script

I'm trying to write a script that downloads a web page that has the URL
for a podcast on it, searches for the URL (which ends with .m4v) and
downloads it to my Desktop.  Here's what I have so far:

wget --no-cache http://podcasturl/podcast.xml
url=`grep .m4v podcast.xml`
wget $url -O ~/Desktop
rm podcast.xml

I know that in the third line grep doesn't work because it returns the
whole line, not just the URL.  Is there anything else I can use to get
it to return just the URL?
