Safari XML parsing broken (Mac, Windows, & iPhone)

Safari (Mac, Windows, & iPhone), does not appear to properly support XML DOM parsing.

I am trying to write a javascript script to parse an XML file and display some of its contents in the HTML.

Perfect example that works for IE 6+, FF, Opera, but not Safari:

Here are the Safari versions I've tried:
Windows (3.0.3)
Mac (2.0.4)
iPhone (whatever version comes on first version)

I desperately need a solution/work-around.

Thank you.
