Python Suds' MessagePlugin does not seem to be updating my output

I am trying to use suds to make a request to a remote SOAP service. I need
to set the namespace on the parameters thus:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:ns0="http://myemployer.com/"
xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header>
<AuthHeader xmlns="http://myemployer.com/">
<Token>blah</Token>
</AuthHeader>
</SOAP-ENV:Header>
<ns1:Body>
<ns0:AwardBadgesBatch>
<ns0:badgeAwards>
<AwardBadge>
<EnterpriseID>jhoov11</EnterpriseID>
...
</AwardBadge>
</ns0:badgeAwards>
<ns0:includeSuccessStatus>false</ns0:includeSuccessStatus>
</ns0:AwardBadgesBatch>
</ns1:Body>
</SOAP-ENV:Envelope>
Note the 'ns0' on both the badgeAwards and includeSuccessStatus elements.
I also need to not have prefixes on the stuff inside badgeAwards.
I am using this code to make the request:
from suds.client import Client
from suds.sax.element import Element
from suds.sax.attribute import Attribute
from suds.plugin import MessagePlugin
import logging
logging.getLogger('suds.client').setLevel(logging.DEBUG)
logging.getLogger('suds.transport').setLevel(logging.DEBUG)
logging.basicConfig(level=logging.DEBUG)
url='https://myemployer.com/BadgingServices.asmx?wsdl'
c = Client(url)
t = c.service.Authenticate('blah')
t = t.Authenticate.Status.Token
header_root = Element('AuthHeader')
header_token = Element('Token').setText(t)
header_attribute = Attribute('xmlns', "http://myemployer.com/")
soap_header = header_root.insert(header_token)
soap_header.append(header_attribute)
class NamespaceFixer(MessagePlugin):
''' must add namespace prefix to all parameters '''
def marshalled(self, context):
body = context.envelope[1]
for i in body[0]:
i.setPrefix('ns0')
print "******* element after setting prefix: %s ********" %
i.plain()
nsf = NamespaceFixer()
c.set_options(soapheaders=soap_header, plugins=[nsf])
from suds.sax.element import Element
ba2 = Element('badgeAwards')
ba = Element('AwardBadge')
ba2.append(ba)
entid = Element('EnterpriseID').setText('jhoov11')
ba.append(entid)
...
includeSuccess = Element('includeSuccessStatus').setText('false')
c.service.AwardBadgesBatch(badgeAwards= ba2,
includeSuccessStatus=includeSuccess)
Now when I do this, I see the xml text output before the marshall() call,
and I see the output from that call:
******* element after setting prefix: <ns0:badgeAwards/> ********
******* element after setting prefix: <ns0:includeSuccessStatus/> ********
but the folks on the other end insist (insist!) that the prefix is not set
on those elements when they receive it.
Two questions come to mind:
am I doing something wrong in my MessagePlugin?
is there a way to display the final modified XML text before it gets sent
off? I think I'm setting it but there's only so much I can say to them
when I can't see the final full text I'm sending.
