Yeah.  Take a look at the SimpleXLMRPC documentation:

    http://docs.python.org/library/simplexmlrpcserver.html

In addition to setting up the server as instructed (let's assume you
assign it to the variable 'server'), you just need to do something like:

    class MyFunctions:

        def showRecord(self, dnsname):
            domain = '.'.join(dnsname.split('.')[1:])
            with open(domain+'.zone')) as myfile:
                # do stuff with data from myfile

    server.register_instance(MyFunctions())


You would modify the body of that function to meet your processing
requirements, of course.  That is, SimpleXMLRPCServer does the request
parsing for you, calls the correspondingly named method, and passes it
the params as method arguments.

(This example is taken from the SimpleXMLRPC documentation, I just
selected one particular way of exposing the methods: via a class
instance).
