Mark -
I've basically done two things in response to the problem you have
identified.
1. I fixed generateDS.py so that it generates export methods that
do not produce extra whitespace (and new lines) when an element
has no children and no character content.
2. I fixed generateDS.py so that it will produce code Python error
in the traceback above (NameError: name 'emptyString' is not defined).
Although, the element definition, in this example:
xs:simpleType name="emptyString"
is basically ignored, I believe that the generated code still does
what you want it to do. So for generateDS.py, the
whiteSpace/collapse thing is unnecessary, but does no harm. I'm
hoping that this will enable you to use the same XML Schema (.xsd
file) with both JAXB and generateDS.py. Please let me know your
thoughts on this.
You can download that latest version with these fixes here:
http://sourceforge.net/projects/generateds/
You can also find it in the usual place at my Web site:
http://www.rexx.com/~dkuhlman/generateDS-1.9a.tar.gz
Thanks much for finding this problem and telling me about it.
Please let me have your comments.
Note that I have also posted this message to the Source Forge email
list for generateDS.py, just in case someone reading that list and
can learn from this.
