[jQuery] iframe and xml

I have been trying to insert xml into an iframe. I can do it kinda. The problem is the iframe has tags and if the xml has items that look like tags like etc they end up in the head. For example I have a atom file that looks like this: http://purl.org/atom/ns#";> Gmail - Inbox for bartonphill.

[jQuery] IFrame and XML

I have a form which has a file input, so I can't use $.post I've, instead, pointed the form at an IFrame. The result of the post is xml. Is there a way to emulate the behaviour of $.post in this regard?
