Also verified that this affects FF 3.6.3 as well. IE 6+ is not affected.

I found a few more things through research today that I think should be taken into consideration when resolving this bug. Please see the references below:

Resetting milestone to future.

#4895 is a duplicate of this ticket.

But does anyone care…?

More details available in ticket 4264 (why are the older XSLT namespace bugs are being marked as duplicates of the newer ones?)

I'll provide a patch as soon as I have some time. I assume that will expedite the resolution? Is there anything else I should supply with the patch that will help with getting this resolved and/or approved for a future release?

Hey! Thanks for the reference to your ticket (which is far more comprehensible than mine). I've altered my local copy of http://gist.github.com/352210 to add the code below and it resolves all errors with all browsers when using jQuery with namespaces (XHTML) and/or using XSLT. I did note, however, that, unlike you, I did not suffer from document.body issues in webkit browsers. This has likely been fixed recently because I recall having issues with them in the past regarding document.body.

Also, if you haven't, make sure you vote this ticket up ;)

// XSLT causes Gecko and Webkit to not set document.body
if( !document.body )
	document.body = document.documentElement.getElementsByTagName("body")[0];

Also, doesn't this belong under support module?

Adequate unit tests must be added to the jQuery Test Suite. Your tests must pass 100% in at least the following:

• Chrome 5
• Safari 3+
• Firefox 3.0.12, 3.5, 3.6, 4
• IE 6+
• Opera 10.60+

I don't think that this is something that we're going to reasonably fix. If a patch with a pull request is issued, pleased feel free to re-open this and we can take a look. Thanks!
