how to write an xml file without dom.ext?

[hackingKK]

Hello all.
I need to create an xml file.
I am using dom.minidom module.
It works fine as long as the xml tree is created.
But I get the import error for dom.ext.
I searched through the python docs but can't find a solution.
I am pritty sure that there is way to write the file to disk without 
using the ext module.
Since there are so many software doing this with python 2.6 I am sure it 
works.
So can some one tell me if there is a way to avoide ext and prittyprint 
and still write a file to the disk?

Happy hacking.
