[Fedora-suds-list] TypeNotFound exception : how to import XSD schema with Python Suds (version 0.3.6) SOAP library ?

[Paul Poulet]

I'm trying to use SABRE travel web services with Python Suds 0.3.6, but one
XSD seems not well-formed (maybe namespace is missing in this schema).

from suds.client import Client
wsdl = '
http://webservices.sabre.com/wsdl/sabreXML1.0.00/tpf/OTA_AirPriceLLSRQ.wsdl'
client = Client(wsdl, cache=None)

Debug trace returns :

Ran 2 tests in 11.669s

Type not found: '(OTA_AirPriceRQ,
http://webservices.sabre.com/sabreXML/2003/07, )'

It's logic : Python Suds loads OTA_AirPriceRQ in a "None" namespace.
I read "fix broken schema" Python Suds documentation (
https://fedorahosted.org/suds/wiki/Documentation#FIXINGBROKENSCHEMAs):

from suds.client import Client
from suds.xsd.doctor import ImportDoctor, Import
wsdl = '
http://webservices.sabre.com/wsdl/sabreXML1.0.00/tpf/OTA_AirPriceLLSRQ.wsdl'
imp = Import('
http://webservices.sabre.com/sabreXML/2003/07/OTA_AirPriceLLSRQ', '
http://webservices.sabre.com/wsdl/sabreXML1.0.00/tpf/OTA_AirPriceLLSRQ.xsd')
d = ImportDoctor(imp)
client = Client(wsdl, cache=None, doctor=d)

But script return another exception :

I don't understand how to use "doctor" functions. Somebody can help me,
please ?
Thank you.
