Here's a page I constructed, and tested on Firefox:
http://intertwingly.net/stories/2007/04/10/test.html
This page is meant to be served as application/xhtml+xml.
Can you test it and see what results you get? Then lets discuss further.
In Safari 2.0.4: Processed as HTML, it says "data" and then "".
Processed as XHTML, it says "null" and then "data".
In Opera 9.00: Processed as HTML, it says "data" and then "null".
Processed as XHTML, it says "null" and then "data".
In Firefox 2.0.0.3: Processed as HTML, it says "data" and then "".
Processed as XHTML, it says "data" and then "data".
In IE/Mac 5.2: Processed as HTML, it says "data" and the second alert
does not appear. Processed as XHTML, neither alert appears.
It looks like Firefox's XHTML implementation already has the
getAttribute extension I suggested of handling QNames.
Firefox is AFAICT the one following spec here. The spec says that
getAttribute in a namespaced document should return the node with the
given qname.
Though I thought we returned null when getAttributeNS failed, but it
appears we only do that for getAttribute.
