Ok. Using pyxb.BIND() that way makes sense. However, i followed your second
suggestion for defining complexTypes at the top and then referencing them
and it was working until the point i wanted to lump them all together into
an xml.
*snippet:*
import organization
import pyxb
pyxb.RequireValidWhenGenerating(False)
org = organization.Organization()
empl = organization.EmployeeType()
addr = organization.AddressType()
org.Name = 'company1'
empl.Name = 'name1'
addr.Street = 'address1'
addr.Town = 'town1'
addr.County = 'county1'
addr.PostCode = '54545'
addr.Country = 'US'
print (org.toxml('utf-8', element_name='Organization'))
*error:*
Traceback (most recent call last):
File "testorganization.py", line 24, in <module>
print (org.toxml('utf-8', element_name='Organization'))
File "/Library/Python/2.7/site-packages/pyxb/binding/basis.py", line 541,
in toxml
dom = self.toDOM(bds, element_name=element_name)
File "/Library/Python/2.7/site-packages/pyxb/binding/basis.py", line 513,
in toDOM
self._toDOM_csc(bds, element)
File "/Library/Python/2.7/site-packages/pyxb/binding/basis.py", line
2661, in _toDOM_csc
content.elementDeclaration.toDOM(dom_support, parent, content.value)
File "/Library/Python/2.7/site-packages/pyxb/binding/content.py", line
1106, in toDOM
raise pyxb.LogicError('toDOM with unrecognized value type %s: %s' %
(type(value), value))
pyxb.exceptions_.LogicError: toDOM with unrecognized value type <class
'pyxb.binding.content._PluralBinding'>: []
I do see the objects for complexTypes getting created if i just use "print
org or print empl or print addr", but get the above error when converting
it to xml.
Tried using append, but couldn't really get it to work.
