RSS Feed Reader

Lets say the user will give me a URL of Dzone as in this one:
http://feeds.dzone.com/dzone/frontpage?format=xml

Now, for my rss feed reader i want to parse it. However, i cant see the XML form of it and i dont know for what keywords to look for. Anyone knows how i can get the xml? I went to dzone.com and clicked rss symbol thing and then clicked "View feed XML". That's how i ended up at the above link.

Thanks.
