this probably isn't your problem, but in your above example getimages
looks like it should be getImages. 

i'm not sure why you want work by hand on the xml-processing, since
xmlrpclib already exists. if you want to debug your setup you can use
shane hathaway's tcpwatch as a proxy which show you what goes out on
the  wire. 

as for the location of such code, it depends on what you're doing with
the results, i think the choices are between a product and an external
method.
