undeterministic behavior of parse_xmlelements #652
Description
Zeep Version 2.4.0
Python: 3.5.2
OS: Ubuntu 16.04.3 LTS (xenial)
I have a very strange problem. I mean "strange" because the output is somehow not deterministic. Which means, sometimes it works as expected and a second later not.
This is the example code (from "Reporting bugs):
import pretend # pip install pretend
from zeep import Client
from zeep.transports import Transport
# Replace YOUR-WSDL and OPERATION_NAME with the wsdl url
# and the method name you are calling. The response
# needs to be set in the content=""" """ var.
client = Client('resource.wsdl')
response = pretend.stub(
status_code=200,
headers={},
content="""<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"><S:Body><ns2:saveResponse xmlns:ns2="http://endpoint.webservice.component.bfabric.org/"><return><resource><errorreport>You have not the permission to perform this update.</errorreport></resource></return></ns2:saveResponse></S:Body></S:Envelope>
""")
operation = client.service._binding._operations['save']
result = client.service._binding.process_reply(
client, operation, response)
print(result)
WSDL and XSD can be found in the gist:
https://gist.github.com/Kunzol/cc1b8156a66505d835b5066e4aab9e3e.js
This is the output I expect:
$ python3 parse.py

'errorreport': None,

],
'role': [],

}
and rerun it a few seconds later I get the error:
$ python3 parse.py

raise XMLParseError("Unexpected element %r" % elements[0].tag)
zeep.exceptions.XMLParseError: Unexpected element 'errorreport'
The error and the correct result can not be predicted. Sometimes I have to run it 10 times, before getting the correct result and sometimes it runs 10 times before getting the error.
This is just one example of my endpoints. There is similar behavior with other endpoints, but this is the "worst" (means more errors than correct results).
With "strict=False" the error does not come up, but the result is different than expected. The _raw_element is filled in this case.
Could this be a problem with the underlaying XML/XSD parser ?
Or a WSDL/XSD size problem?
Any ideas ?
Thanks for your help in advance.
