Guess you can have a textarea in the html file and put the xml you want user to edit. User can edit the file and submit when they are done.

By edit XML do you mean:
1. edit the content of existing fields, not changing the XML structure
-or-
2. edit both content and XML markup, adding or removing elements, attributes, etc.

For 1 you just need to create a normal form and populate it with the editable data. For 2 things get a LOT more complicated.
