If you can’t clear out enough “junk” with the to\_xml options:

[http://api.rubyonrails.org/classes/ActiveRecord/XmlSerialization.html#M000910](http://api.rubyonrails.org/classes/ActiveRecord/XmlSerialization.html#M000910)

then override to\_xml on your model to produce the xml you want…  
probably with builder. You can also make a builder rxml template and  
have the controller render that instead.
