By my reading of the XML-RPC spec, XML-RPC is a specification owned by
Userland Software(A Dave Winer work it seems), just using a very basic
glance its a considerably simplier protocol than SOAP.
SOAP, on the other hand, is a w3c spec. A bit more complex but probably more
versitile(I am not really a SOAP guy, I just know bits and pieces).
Thanks for your post. I believe the following is helpful for discussing
XML-RPC vs SOAP and offering a simple guide to choose the best protocol for
your XML Remote Procedure Call needs.
