[python-win32] Accessing a dictionary like object using WebServices from Win32

[Gary Hubbard]

Hi

I am trying to communicate with a vendor's WebService, using PyWin32.  I am 
successful using most of the methods, but I don't know how to interpret those 
returning a dictionary like object.

Obfuscating the vendor name with XXX everywhere, to avoid checking on whether it 
is acceptable to communicate about this, the code looks like

    sc = win32com.client.Dispatch("MSSOAP.SoapClient")
    sc.mssoapinit("http://localhost:1024/wsdl/IXXXWebService")
    sc.connect()
    ret = sc.ReadMeasureDataParam(paramName)

Under C# or VB, ret would be a dictionary like object with 6 different keys, 
such as LongName and ShortName, accessed as ret.LongName, etc.  Using that under 
PyWin32 gives an attribute error, but I can index with the [0] to [5].  
Unfortunately, doing that still returns an object I don't know how to interpret.

There are several other functions that have the same issue, but I think the 
basic problem is identical.

The relevant XML code follows.  I manually chopped the code apart, eliminating 
what I though was unnecessary. 

Thanks,
