That should all work. I just took a look at the Apple "NewMusic"
sample, which uses XPath to scrape info out of eMusic's RSS feed
entries, and it uses path expressions like
//a[starts-with(@href,'http://www.emusic.com/artist/')]/@href
It's not exactly what you're doing, but it's definitely matching on
attribute values. You might look at the sample code for clues.
