#100 Generating bindings for XSD with extensions containing wildcards can cause exception

[Buse]

I have the following schema:

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    version="1.0" targetNamespace="http://www.example.com/test" xmlns:tgt="http://www.example.com/test" 
    elementFormDefault="qualified" attributeFormDefault="unqualified">

  <complexType name="BaseRequestType" abstract="true">
    <attribute  name="attrib1"  type="xsd:string"/>
    <anyAttribute namespace="##any" processContents="skip"/>
  </complexType>

  <element name="Notification">
    <complexType>
      <complexContent>
        <extension base="tgt:BaseRequestType">
          <attribute name="attrib2"         type="xsd:string"         use="optional"/>
          <anyAttribute  namespace="##any" processContents="skip"/> 
        </extension>
      </complexContent>
    </complexType>
  </element>

</schema>

Running this through pyxbgen gives the following traceback:

Exception generating bindings: _setAttributeWildcard() got an unexpected keyword argument 'process_contents'

I realize the anyAttribute tags are doubled up. But it should still be parseable and valid, even if it doesn't make much logical sense.

• attachment _trac-100.patch_ added

Potential fix for problem

[Peter A. Bigot]

• status changed from new to assigned

See whether the trac-100.patch I just posted fixes this. It builds; whether it does the right thing is currently untested. (The patch is against the development version, but except for line numbers it's probably right for 1.1.2.)

[Buse]

The patch seems to fix things.

Thank you.
