Bob,
I ran generateDS.py against the XML schema you sent me.
In class ReferenceType, I get this generated code for exportChildren:
def exportChildren(self, outfile, level, namespace_='ds:',
name_='ReferenceType', fromsubclass_=False, pretty_print=True):
if pretty_print:
eol_ = '\n'
else:
eol_ = ''
if self.Transforms is not None:
self.Transforms.export(outfile, level, namespace_='ds:',
name_='Transforms', pretty_print=pretty_print)
if self.DigestMethod is not None:
self.DigestMethod.export(outfile, level, namespace_='ds:',
name_='DigestMethod', pretty_print=pretty_print)
if self.DigestValue is not None:
showIndent(outfile, level, pretty_print)
outfile.write('<%sDigestValue>%s</%sDigestValue>%s' % (namespace_,
self.gds_format_base64(self.DigestValue, input_name='DigestValue'), namespace_,
eol_))
In the header line of this function, the namespace_ parameter gets
the default value 'ds:', whereas in your generated code (below) it
has the value 'oadr:'. Am I right that the above code would handle
your issue correctly? I've attached my generated file (which I
swear that I did not manually doctor. Honest.) to a separate email.
So, why is your generated code different from mine?
Is it possible that we are using different versions of
generateDS.py? You can look at the top of that generated file to
find the version. You can also see, near the top of the file, what
command line and options I used to generate it.
If you suspect that this problem is happening because your version
is different from mine, you can find the latest version (which I am
using) at https://bitbucket.org/dkuhlman/generateds.
And, if it is not the version, then perhaps you could show me what
command line you used to generate your code (or send me the file,
since it has the command line options at the top). Perhaps there is
some option that is causing the problem. I tried several different
command lines, but they produced the same thing. I tried the
following command lines:
$ ./generateDS.py -f -o "tmp01sup.py" -s "tmp01sub.py" --super="tmp01sup"
--member-specs="dict" xmldsig-core-schema.xsd
$ ./generateDS.py -f -o "tmp2.py" xmldsig-core-schema.xsd
And, I get the same thing whether I use Python 2.7 or Python 3.6.
I need a clue. Hope your weekend is/was a good one.
Dave
