Hi Jamie, Yes, Nik2img should handle loading XML and XML entities no differently than mapnik does in general.
All nik2img does is call mapnik.load_map() internally.

In this case I think it is as well. I bet that you are running libxml2 and it is simply a parsing error that is being thrown not by Mapnik but by libxml2. Things that might be causing it: 1) some character that is not encoded, such as a '>' that should be '>' 2) The user running nik2img does not have proper permissions to access one of your entity files. 3) The paths to one of the entities is relative or otherwise not available for the nik2img process. If these ideas don't help can you: 1) Simply try loading the xml in an interpreter session from the same directory you are running nik2img: $ cd <dir you ran nik2img> $ python >>> import mapnik >>> m = mapnik.Map(1,1) >>> mapnik.load_map(m,'/media/data/mapfile/mapfile.xml') And then see what happens...
