Fails to load WSDL provided by BEA WebLogic Server

[GoogleCodeExporter]

What steps will reproduce the problem?
1. from pysimplesoap.client import SoapClient
2. SoapClient('http://www.destin8.co.uk/ISLInterface/ISLInterface?WSDL')

What is the expected output? What do you see instead?

The SoapClient instance should be initialised from the WSDL. It instead throws 
the following exception;

  ...
  File "./aisarchive.py", line 52, in _create_client
    result = SoapClient(wsdl='%s?WSDL' % self._url, trace=True)
  File "/export/home/henry/code/lib/pysimplesoap/pysimplesoap/client.py", line 68, in __init__
    self.services = wsdl and self.wsdl(wsdl, debug=trace, cache=cache)

    process_element(element_name, children)

    uri = ns and e.get_namespace_uri(ns) or xsd_uri
  File "/export/home/henry/code/lib/pysimplesoap/pysimplesoap/simplexml.py", line 182, in get_namespace_uri
    v = self.__document.documentElement.attributes['xmlns:%s' % ns]
  File "/usr/local/lib/python2.6/xml/dom/minidom.py", line 530, in __getitem__
    return self._attrs[attname_or_tuple]
KeyError: u'xmlns:xsd'

What version of the product are you using? On what operating system?

pysimplesoap-1.02c.zip
BEA WebLogic Server 8.1

Please provide any additional information below.

The problem is the 'xsd' namespace found under schema elements.

This isn't the server I'm using; the WSDL is from a server I found online 
(http://www.google.com/search?q=%22For+a+formal+definition,+please+review+the+Se
rvice+Description%22+%22BEA+WebLogic+Server+8.1%22).

The problem is that SimpleXMLElement only looks in the document element for 
namespaces; it can be in the element itself, or any ancestor element. Here is a 
simple patch that fixes the issue for me.
