xml.minidom and user defined entities

[Nick Craig-Wood]

I'm using xml.minidom to parse some of our XML files.  Some of these
have entities like "°" in which aren't understood by xml.minidom.
These give this error.

  xml.parsers.expat.ExpatError: undefined entity: line 12, column 1

Does anyone know how to add entities when using xml.minidom?

I've spend some time searching the docs/code/google but I haven't
found the answer to this question!

Thanks
