Joel,
Hello. Here are some attempts at answering several of your
questions.

You could consider copying the `parse` function in a module
generated by `generateDS.py` with the "-o" command line option.
You'd copy it to a separate module/script and then modify it however
you want, for example, adding your custom xml preamble. For
example, after running:
$ generateDS.py -o mymodule.py myschema.xsd
you might write a module:
import sys
import mymodule
def get_root_tag(node):
tag = Tag_pattern_.match(node.tag).groups()[-1]
rootClass = GDSClassesMapping.get(tag)
if rootClass is None:
rootClass = globals().get(tag)
return tag, rootClass
def parse(inFileName, silence=False):
parser = None
doc = parsexml_(inFileName, parser)
rootNode = doc.getroot()
rootTag, rootClass = get_root_tag(rootNode)
if rootClass is None:
rootTag = 'mailboxType'
rootClass = mailboxType
rootObj = rootClass.factory()
rootObj.build(rootNode)
# Enable Python to collect the space used by the DOM.
doc = None
if not silence:
#
# Add my custom XML preamble here:
#
#sys.stdout.write('<?xml version="1.0" ?>\n')
sys.stdout.write('<?xml version="1.0" encoding="UTF-8"
standalone="yes"?>\n')
rootObj.export(
sys.stdout, 0, name_=rootTag,
namespacedef_='',
pretty_print=True)
return rootObj
def test():
rootObj = parse("my_xml_instance_doc.xml")
o
o
o
test()
Note how I've modified the call to `sys.stdout.write` to write out
your XML preamble.
Would that technique work for you?

This one I don't understand. But, with my dim and weak grasp of
namespaces, that's to be expected.

Does command line option -c do what you need? From the help
(produced with `generateDS.py --help`):
-c <xmlcatalogfilename> Input file name to load an XML catalog
You can look in `process_includes.py` to try to figure out how that
is used. Search for "catalog".
There is actually a unit test for this (in `generateds/tests`), but
it appears empty to me. So, if this is the feature you need, and it
does not work as you'd expect it, please let me know so that I can
try to fix it. Here is some documentation on XML catalogs that I've
found on the Web:
- https://www.oasis-open.org/committees/download.php/14809/xml-catalogs.html
- https://xerces.apache.org/xerces2-j/faq-xcatalogs.html.

Hope this helps.
