Mike -
Thanks for reporting this.
I was able to download the Spirit schema files, and I was able
reproduce that error. I get the same error message that you get.
After poking around a bit, I found that those schema files reference
an attributeGroup named "spirit:long.att" that is not defined. I
don't know why it is not defined, perhaps we're missing a file.
generateDS.py definitely needs to be able to handle that in a more
graceful and informative way.
So, I've made a patch. Basically, with this patch, we're ignoring
any attributeGroup reference to an undefined attributeGroup. So,
we're saying, in effect, that when the author of a schema references
an attributeGroup, but does not define that attributeGroup, s/he
intends that attributeGroup to be empty. Does that seem reasonable?
An alternative would be to write out an error message (something
like "attributeGroup 'XYZ' missing"), and quit. I think it's better
to be able to generate the python bindings/classes. Or, I could
write out a warning message, but in the case of the Spirit Schema,
this would result in over 70 warning messages. So, I'll leave out
the warning message. What do you think?
With this patched version, I was able to generate output.
I'll send a new version containing this patch in a separate email.
Let me know how well this works for you. And, as always, hope this
helps.
