Parsing WSDL Documents with Zeep Library

This section provides a tutorial example on how to parse WSDL documents and print out available services using Zeep default script. Zeep library supports WSDL 1.1 documents, not WSDL 2.0 documents.

Once the Zeep library is installed, you can use it to parse a given WSDL document and print out available services by running its default script:

python3 -mzeep <wsdl_url>

1. Parse a WSDL 1.1 document as a local file, Hello_WSDL_11_SOAP.wsdl, created in previous tutorials.

herong$ python3 -mzeep file:///Users/herong/Hello_WSDL_11_SOAP.wsdl

Prefixes:
     xsd: http://www.w3.org/2001/XMLSchema
     ns0: https://www.herongyang.com/Service/

Global elements:
     ns0:HelloRequest(xsd:string)
     ns0:HelloResponse(xsd:string)
     
Global types:
     xsd:anyType
     xsd:ENTITIES
     xsd:ENTITY
     xsd:ID
     ...
     xsd:unsignedShort

Bindings:
     Soap11Binding: {https://www.herongyang.com/Service/}helloBinding

Service: helloService
     Port: helloPort (Soap11Binding: 
                    {https://www.herongyang.com/Service/}helloBinding)
         Operations:
            Hello(xsd:string) -> xsd:string

Cool! It parsed the WSDL 1.1 document correctly.

2. Parse an online version of the same WSDL 1.1 document. I got the same output:

herong$ python3 -mzeep \
  https://www.herongyang.com/Service/Hello_WSDL_11_SOAP.wsdl

...
Service: helloService
     Port: helloPort (Soap11Binding: 
                    {https://www.herongyang.com/Service/}helloBinding)
         Operations:
            Hello(xsd:string) -> xsd:string

3. Parse an online version of a WSDL 2.0 document. I got no bindings and servers:

herong$ python3 -mzeep \
  https://www.herongyang.com/Service/Hello_WSDL_20_SOAP.wsdl

Prefixes:
     xsd: http://www.w3.org/2001/XMLSchema

Global elements:
     
Global types:
      xsd:anyType
      xsd:ENTITIES
      xsd:ENTITY
      xsd:ID
      ...
      xsd:unsignedShort

Bindings:

Zeep library actually does not support WSDL 2.0 documents. It should return an error message.

Conclusion: Zeep library supports WSDL 1.1 documents. It does not support WSDL 2.0 documents.
