[Zope] How do I form an XML-RPC query to a remote server?

[Tony McDonald]

Hi all,
I'm experimenting with collating data from a remote database that uses
XML-RPC.

I can send it messages like;
>>> import xmlrpclib
>>> medweb = xmlrpclib.Server("http://bogus.server.com")
>>> medweb.getImages('scar')
'<?xml version="1.0" encoding="ISO-8859-1"
?>\015\012\011<data>\015\012\011\011<title>Medwebb Images</title> \0

(lots of stuff snipped)

But I just can't figure out how to send the XML version of the same query,
ie
<?XML VERSION="1.0"?>
<methodCall>
    <methodName>getimages</methodName>
    <params>
        <param>
            <value><string>scar</string></value>
            </param>
        </params>
    </methodCall>

to the server.

I've got a nasty feeling that when I get told how to do this, I'm going to
slap my forehead bloody hard....

As you can see the data is returned in XML format, and whilst I'm fine with
Python code for XML parsing (usually use sgmlop), I'm a bit lost on where to
start here. An External Method seems the best way, but I'd like the received
wisdom on this.

Ta muchly,
tone
