Hi Dave,
Thanks for the reply. Just using vanilla generateDS if an element is set to
none e.g.
insps = spsclasses.inspections()
insp = spssubclasses.inspectionTypeSub()
insp.set_forestManager("NZFyOA")
insp.set_bioRegion("absjk876%")
insp.set_diam(None)
....
insp.set_serialNumber(None)
insp.set_stand("")
insp.set_inspType("FBS")
insps.export(outfile,0)
the diam element will not be written to the output xml
<inspections>
<inspection>
<forestManager>NZFyOA</forestManager>
<stand></stand>
<bioRegion>absjk876%</bioRegion>
<inspType>FBS</inspType>
</inspection>
</inspections>
What I need is this for this particular customer is all elements set to None
output like:
<?xml version="1.0" encoding="utf-8"?>
<inspections>
<inspection>
<serialNumber />
<forestManager>NZFyOA</forestManager>
<location />
<stand></stand>
<siteId />
<subSite />
<bioRegion>absjk876%</bioRegion>
<siteType />
<date />
<inspector />
<hostSpec />
<estabYear />
<treatment />
<stemsPerHa />
<diam />
<height />
<inspType>FBS</inspType>
<sampleType />
<points />
<disorders />
<identifications />
</inspection>
</inspections>
I reread the doc and came up with a solution - to override the export function
in the subclass like this - I also made an assumption on how you are naming
your properties
def exportChildren(self, outfile, level, namespace_='',
name_='inspectionType', fromsubclass_=False, pretty_print=True):
if pretty_print:
eol_ = '\n'
else:
eol_ = ''
#based on schema we assume that no _ in field names - filters out
generateds stuff
for attr, value in self.__dict__.items():
print(attr, value)
if "_" in attr:
continue
else:
if value is not None:
supermod.showIndent(outfile, level, pretty_print)
outfile.write('<{0}>{1}</{0}>{2}'.format(attr,
self.gds_encode(
self.gds_format_string(supermod.quote_xml(value),
input_name=attr)),
eol_))
else:
supermod.showIndent(outfile, level, pretty_print)
outfile.write('<{0} />{1}'.format(attr,eol_))
if self.points is not None:
self.points.export(outfile, level, namespace_, name_='points',
pretty_print=pretty_print)
if self.disorders is not None:
self.disorders.export(outfile, level, namespace_,
name_='disorders', pretty_print=pretty_print)
if self.identifications is not None:
self.identifications.export(outfile, level, namespace_,
name_='identifications', pretty_print=pretty_print)
which does what I want but I lose this the next time the schema is updated and
the classes regenerated - so updating the source would be more elegant.
I take a look at those functions today and see what I can do. I have installed
via pip so can I updated the generateDS.py directly?
Appreciate the reply - thanks very much - and it's a super useful library
Thanks,
Fraser

Fraser,
Good to hear from you. Wow. That version goes back a bit.
Let me try to repeat back your request so that we're sure I understand it
correctly.
You would like elements of type xs:string to be always exported even if their
value is None.
You might take a look at the code that generates the export functions to see if
there is some reasonably easy modification that would give you what you need.
I believe the code that you would be interested in is in `generateDS.py` in the
functions `generateExportFn_1` and `generateExportFn_3`. One of these handles
the case where the element is optional (defined with minOccurs="0").
Look for the test for "StringType". It looks to me like you should be able to
add generation of an `else` clause that gets you what you want.
Hope this helps.
Dave
