Hi Dave,
Thank you for the new version. Unfortunately it doesn't seem to work for me
yet. I have the following definition:
<xs:element name="MetaConstruct">
<xs:complexType>
<xs:attribute name="name" type="xs:string" />
<xs:attribute name="dataType" type="dataTypeEnum" />
</xs:complexType>
</xs:element>
As you can see, this type can not have any children. However, the export
function it generates does seem to want to export children:
def export(self, outfile, level, namespace_='', name_='MetaConstruct'):
showIndent(outfile, level)
outfile.write('<%s%s' % (namespace_, name_))
self.exportAttributes(outfile, level, namespace_,
name_='MetaConstruct')
outfile.write('>\n')
self.exportChildren(outfile, level + 1, namespace_, name_)
outfile.write('</%s%s>\n' % (namespace_, name_))
I've looked through generateDS's code, and I found the following (line 1487):
elif childCount == 0:
s1 = " outfile.write('>\\n')\n"
outfile.write(s1)
s1 = " self.exportChildren(outfile, level + 1, namespace_,
name_)\n"
outfile.write(s1)
s1 = " outfile.write('</%s%s>\\n' % (namespace_, name_))\n"
outfile.write(s1)
I was wondering if this shouldn't say:
elif childCount == 0:
s1 = " outfile.write(' />\\n')\n"
outfile.write(s1)
Because you know it doesn't allow any children. Then you don't need to check
for them.
Regards,
Vincent
