I did some cleanup on this to make it a) prettier and b) more resilient.

The file is attached.

Basically, I've found that you need one xmlcontent to create a new one even 
if you can get the button to display. It uses the existing one to set up 
the editing for the one being created.  :P  So, you'll notice that I point 
to a xmlcontent called /internal/news_001.html for the create form and 
store my real xmlcontent in a different directory.  That way a user won't 
see it or accidentally delete it and cause the add button to no longer work.

I changed the submit buttons to links that use javascript to submit and 
threw it in a table format.

I also wrapped a check around the whole thing to not display anything if 
the user is the "Guest" user, ie: viewing the published site.  Without 
this, the edit links appear on the published site.  You could get fancier 
and just disable the links...but I just disabled viewing too.
