[pyxb-users] generating xml documents from python instances

[victor <noa...@gm...>]

hi list,

i'm trying to generate an xml document from python instances but when
i invoke the toxml() function, bunch of ns1s occur in the final
string.

so i created my module this way:

python C:\lib\PyXB-1.1.2\scripts\pyxbgen -u file:pain.xsd -m pain

then i did this in the interactive interface:

>>> p = pain.Document()
>>> p.CstmrDrctDbtInitn = pain.CustomerDirectDebitInitiationV02()
>>> p.CstmrDrctDbtInitn.GrpHdr = pain.GroupHeader39()
>>> p.CstmrDrctDbtInitn.GrpHdr.MsgId = pain.Max35Text('CAVAY1234')
>>> p.toxml()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "c:\lib\pyxb-1.1.2\pyxb\binding\basis.py", line 367, in toxml
    dom = self.toDOM(bds)
  File "c:\lib\pyxb-1.1.2\pyxb\binding\basis.py", line 353, in toDOM
    self._toDOM_csc(bds, element)
  File "c:\lib\pyxb-1.1.2\pyxb\binding\basis.py", line 2153, in _toDOM_csc
    eu.toDOM(dom_support, parent, v)
  File "c:\lib\pyxb-1.1.2\pyxb\binding\content.py", line 578, in toDOM
    value._toDOM_csc(dom_support, element)
  File "c:\lib\pyxb-1.1.2\pyxb\binding\basis.py", line 2144, in _toDOM_csc
    raise pyxb.DOMGenerationError('Binding value inconsistent with
content model')
pyxb.exceptions_.DOMGenerationError: Binding value inconsistent with
content model

but then i did

>>> import pyxb
>>> pyxb.RequireValidWhenGenerating(False)
>>> p.toxml()

and i get this

u'<?xml version="1.0" ?><ns1:Document
xmlns:ns1="urn:iso:std:iso:20022:tech:xsd:pain.008.001.02"><ns1:CstmrDrctDbtInitn><ns1:GrpHdr><ns1:Msg
Id>CAVAY1234</ns1:MsgId></ns1:GrpHdr></ns1:CstmrDrctDbtInitn></ns1:Document>'


any idea why i am getting those ns1?
