Do you mean ${XML(item.code)} instead ?

maybe you should just pass a callable that returns an xml.etree.Element
(with subelements in there of course)
I would do this like the following and then my web designer who does CSS
would like me even more :)
first in the controller (I put some dummy stuff to emulate yours):
http://paste.turbogears.org/paste/1314
then in the template:
http://paste.turbogears.org/paste/1315
as you can see I imagined some simplified model (Item class here) to
emulate yours but I think this is one way to get what you want.
The js code is also simplified because I did not know what was profile
(a dictionnary of something it seems).
This code was tested in a quickstarted TG 1.0.2.2 app with genshi
templating.
Hope it helps,
Florent.
