Zeep SOAP client: No element 'DocumentElement' in namespace None. Available elements are: NewDataSet

[jurrian]

Replacing suds SOAP client by zeep caused the following exception for all usage of the GetListReport operation: No element 'DocumentElement' in namespace None. Available elements are: NewDataSet.

After some extensive investigation it turns out that not the Zeep package is doing it wrong but the data supplier iBabs is malformed. It turns out that there is a mismatch between the NewDataSet which is defined in the scheme and DocumentElement which is listed in the data itself. I have contacted iBabs and suggested to replace NewDataSet by the latter to resolve the issue. As far as I know GetListReport is the only operation that includes a XML Schema.

Further, since there is currently no obvious way around malformed data, I've created an issue to request a setting to ignore the supplied XML schema. For an example of the malformed data see:

iBabs has been working on a new method called GetListReportDataSet that will have the right XML Schema, with an DocumentElement. This issue will be closed when that comes to production.
