Error while pinging Pingomatic (XMLRPC) using python

Question

I'm trying to ping Pingomatic using python.

I've written this:

import xmlrpclib

print "START"

s = xmlrpclib.Server('http://rpc.pingomatic.com')
reply = s.weblogUpdates.ping('Test','http://www.testblog.com')

print "END"

But when I run, i get:

>>> 
START

Traceback (most recent call last):
  File "C:/xxxxxxxxxxxxxxxxxx/pingtest1.py", line 6, in <module>
    reply = j.weblogUpdates.ping('Test','http://www.testblog.com')
  File "C:\Python27\lib\xmlrpclib.py", line 1224, in __call__
    return self.__send(self.__name, args)
  File "C:\Python27\lib\xmlrpclib.py", line 1570, in __request
    verbose=self.__verbose
  File "C:\Python27\lib\xmlrpclib.py", line 1264, in request
    return self.single_request(host, handler, request_body, verbose)
  File "C:\Python27\lib\xmlrpclib.py", line 1297, in single_request
    return self.parse_response(response)
  File "C:\Python27\lib\xmlrpclib.py", line 1462, in parse_response
    p.feed(data)
  File "C:\Python27\lib\xmlrpclib.py", line 557, in feed
    self._parser.Parse(data, 0)
ExpatError: syntax error: line 1, column 0
>>> 

How can I fix this?

Thank you.

It turns out this was an issue with Pingomatic's response format. I tried pinging Weblogs.com, and it worked fine.

I emailed Automattic to let them know, and they've since fixed the issue -- everything should be working!
