Django: Double-Escape XML Entities

Question

Running into a bit of a corner case: the API I'm communicating with blows up when there's an ampersand or similar in the data, even though Django is escaping the data when rendering the XML template. The response I get from the API owner was:

Sensibly, Django doesn't really make this easy. Trying |escape|escape doesn't do what I want regardless of whether autoescape is on or off. I'm sure I can write a custom filter to do this, but I'm worried that will lead to other issues. Is there a simple way to do this with standard template filters?

Answer 1

The Django force_escape filter should work if applied twice.
