Depends if your wanting to do what im wanting to do and read xml to html but then again if not you could do this...

<link rel="alternate" type="application/rss+xml" title="Rss" href="rss.xml">

Puts the ison for Rss into the seach bar !
Then just create an xml file with <rss version=""></rss> to go with it.

The trouble I'm having myself though is that it won't show any of the items once i've added it to the bookmarks. Can anyone help me with formatting my XML file please!?
