Do you get an error message?

My guess is that the parser needs the DTD but cannot access it. There
appears to be a DTD at that address, http://java.sun.com/... (it
redirects to Oracle, who bought Sun a while ago), but something might
prevent the parser from accessing it by default. If so, the details
depend on what parser you are trying to use. It may be possible to save
that DTD as a local file and point the parser to that.

Your problem is morphing rather wildly. A previous version had namespace
declarations but no DTD or XSD if I remember right. The initial version
wasn't XML at all.

If you post (1) an actual, minimal document, (2) the actual Python
commands that fail to parse it, and (3) the error message you get,
someone will be able to help you. The content of the document need not
be more than "hello, world" level. The DOCTYPE declaration and the
outermost tags with all their attributes and namespace declarations, if
any, are important.
