How can I access an RSS Feed from a SharePoint XML Viewer?

I'm trying to use the XML Viewer to pull an RSS feed and apply a simple XSLT to it. The RSS happens to be the RSS from a SharePoint List (different sites need to share lists). While the XML Link will successfully connect to an RSS file (The "Test Link" link in the [XML Viewer] Property Panel works), it will not display, with, or without the XSL.
