Is this something that jQuery could handle?
Sorry, that's well past the limits of my knowledge.
See how I'm not punching him? I think I've grown.

This works but can be slow. Using the XSL transformation would (I think) increase performance.
I doubt it will increase performance. I'm surprised you're finding modifying one DOM node in an XML DOM to be slow. How do you measure its performance?

Sir, it's not an offence to let your cat eat your bacon. Okay? And we don't arrest cats, I'm very sorry.

Well, it's more like dozens or hundreds of DOM nodes. With three or more levels of looping.
How do you measure its performance?
With JavaScript alerts before and after all the looping.

With hundreds of nodes I could imagine XSLT might be faster, but I'd think JavaScript would be pretty fast too.
What browser are you using to measure performance? Chrome has some profiling tools that might help you figure out if you can make the JavaScript code fast enough.

I'm using IE 8. The application is IE-only. We've done a fair amount of JavaScript optimization already.
JavaScript on IE 9 is supposed to be faster (or was that 8?) but our client hasn't upgraded to IE 9 yet.

IE 9 is supposed to have a better Javascript engine.

I'm afraid I don't know anything about XSLT.

Does the version of Javascript you're using have E4X? [link]

Actually, I got the xsl transformations working. The problem I'm having is the result of an xsl transformation is not a JavaScript object but just text (XML, in this case.) So I pull the result into a DOM DocumentFragment and then I try to do an AppendChild of the DocumentFragment into a different XML object, but that doesn't work.
