[XML-SIG] Python Web Service Client Question

Good afternoon,

         I'm trying to write a simple web service client in Python.  The 
web service I'm trying to access is simple.  It takes an integer and 
returns a String.  For some reason, when Python serializes the request, I 
get this snippet (sanitized a bit):

<empno xsi:type="xsd:integer">123</empno>

     The web service complains that it expects a simple type, and I can 
understand why, given what I pasted above.

     I can get Python to name the first <empno> whatever I want it to be 
named, but I can't get Python to remove it.  So, I guess there are two 

1) Figure out how to get Python to remove the outer <empno>
2) Name the outer <empno> something that the web service won't complain 
about (i.e., <doNotParseMe>)

     I can't figure out how to do either of the two approaches.  Perhaps 
there is also another approach (this is only my second day coding in 
Python, though I'm already thoroughly amazed by the language).

         Here is the Python web service client code:

from ZSI.client import Binding
from ZSI import TC

log_file = open('soaplog.txt', 'w+')
u = '/WebService.jws'
n = 'http://www.openuri.org/'
b = Binding(url=u, ns=n, host='localhost', port=7001, tracefile=log_file)

class MyInt:
     def __init__(self, Empno):
MyInt.typecode=TC.Struct(MyInt, [TC.Integer('empno')], 'empno')


print result
