Python SUDS Error - SAXParseException

Question

Does anyone know why I would get a "<unknown>:1:0: syntax error" from a python suds call when the response looks like this?

<?xml version='1.0' encoding='UTF-8'?>
<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope">
  <env:Body>

      </business.document.header.types:businessDocumentHeader>
    </external.bz1:reply>
  </env:Body>
</env:Envelope>

Here is the stack trace:

Exception Type: SAXParseException at /businessNames/externalBz1/1/

That's straight from the log, with no mention of the parse error :(

Any ideas?

Cheers, Ben

I instead of directly passing the result, I did the following and it got rid of the error.

sax = suds.sax.parser.Parser()

s_received = str(client.last_received())   # passed "client.last_received()", no error 

s_parse = sax.parse(string=s_received)

Instead of something like:

x_request = eval(client.service.ListTestAccounts)

result = x_request("1")

sax = suds.sax.parser.Parser()

s_result = str(result)           # passed "result", generated error

s_parse = sax.parse(string=s_result)

Hope this helped.
