IMHO the questions you ask here are Dia interface questions more than
Python questions. Although my answers aren't responsive to your exact
questions, you might find them helpful.

My Dia has no Python scripting, and I don't know what codegen.py is,
but...

If you just zless yourdiagram.dia | yourpgm.py , then stdout will be the
terminal unless you redirect the output.

This becomes a moot question if you run your python program against the
Dia diagram file on the command prompt.
One more thing. If you put the following line:
from lxml import etree
near the top of your program, then you have an XML parser with which
you can disect any ungzipped XML and have your way with it.
You could also use:
import xml.etree.ElementTree as ET
but in my opinion the former XML parser is more useful than the latter
for most work.
I know this wasn't responsive to your question, but I hope it helps.
