about XML

I wrote a little thing that writes an internal text in xml, using some datas of the current scene (for blended cities purposes / 2.49)
also I use xml for the library categorization of the script. it uses minidom, so it needs a complete python install.

I was wondering : I red an ‘old’ thread about XML in this section talking about more simple, stand-alone implementation of xml parser/writer.
and also a project about a blender file format in XML.
have you some pointers about it ?
thanks,

the little thing I talk about
