- What is XML-RPC?
Machines need to talk to each other, but they all speak different languages. In order for them to communicate, they need a common ground for talking, a set of rules they could all follow and use to understand each other. XML-RPC is the name of one of the sets of rules people come up with. There are other specification of rules apart from XML-RPC, like JSON-RPC, SOAP, WSDL, CORBA and REST.
