JavaScript Atom Feed Parser

Wrote a JavaScript Atom (http://www.mnot.net/drafts/draft-nottingham-atom-format-02.html) Feed Parser. It's at http://premshree.resource-locator.com/javascripts/atom-parser.htm

Oops...almost forgot to mention. You need to save the file to your desktop to run it. Won't run remotely.

Why don't you use a signed script for ie, and UniversalBrowserRead for Mozilla?

I tried the exact same thing with the RSS 2.0 parser I coded. For whatever reason, it won't run online... it only seems to run reliably locally.

It doesn't seem to parse out very much. Apparently, it only parses the title, link, and description. What about the other data, nodes, and the entire specification? Any future plans?

I'm working on a JavaScript Feed Parser myself, but my goal is for complete support for all tags in the RSS 0.9x, 1.0, 2.0, and Atom 0.3 specifications, as well as some of the more popular namespace add-ons.

What are the drawbacks of your script? Is it case-sensitive? Will it fail otherwise? How much testing on a variety of Atom feeds have you done? Well-formed? Not well formed? Atom versions prior to 0.3?

Sorry for the third degree, but as I said, I'm working on a similar project, and I'm interested in picking your brain.
