What is XML-RPC?
XML-RPC is a protocol that uses XML messages to perform Remote Procedure Calls. Requests are encoded in XML and sent via HTTP POST; XML responses are embedded in the body of the HTTP response. More succinctly, XML-RPC = HTTP + XML + Remote Procedure Calls.
Because XML-RPC is platform independent, diverse applications can communicate with one another. For example, a Java client can speak XML-RPC to a Perl server. To get a quick sense of XML-RPC, here is a sample XML-RPC request to a weather service (with the HTTP Headers omitted): weather.getWeather
10016 The request consists of a simple element, which specifies the method name (getWeather) and any method parameters (zip code).
65 The response consists of a single element, which specifies the return value (the current temperature). In this case, the return value is specified as an integer. In many ways, XML-RPC is much simpler than SOAP, and therefore represents the easiest way to get started with Web services. The official XML-RPC specification is available at XML-RPC.com. Dozens of XML-RPC implementations are available in Perl, Python, Java, and Ruby. See the XML-RPC home page for a complete list of implementations.
