Hello.
That's a somewhat generic (and not very informative) error
message that generateDS.py gives when it fails to build the
data structures it needs to enable it to generate Python code.
One common problem is the namespace prefix used in the
schema file. If it is other than "xs:", you will need to use the -a
command line option. An example:
generateDS.py -a "xsd:" -o mylib.py -s myapp.py --super=mylib myschema.xsd
If you could send me your schema (or let me know where I
can go to download it), I'll take a look.
Wait. I found EMSFlightMonitorService.xsd with a Web search. And, yes,
the namespace prefix was causing this problem. (I really need to
document that better, or something. Or, is this just a good way
for me to get an email once in awhile from a user.)
Anyway, I was able to generate files with the following command line:
generateDS.py -a xsd: --super=tmp1sup -o tmp1sup.py -s tmp1sub.py
EMSFlightMonitorService.xsd
I also was able to import that file in Python. So, that tells us that
the code is legal Python code.
But, I do not have any instance documents, so I can't really do
any further testing.
So, please let me know what happens when you try it on an
XML instance document that obeys that schema.
