SOAP transmits method arguments

Question

Compare the way SOAP transmits method arguments with the way that SunRPC transmits procedure arguments.

Answer 1

SOAP supports document-level transfer, while xml-rpc is more regarding values transfer, though it can transfer structures like structs, lists, and so on while as xml-rpc has a few issues with non-ascii character sets.

The client invokes a procedure or method on a remote server by transmitting a SOAP message to the server. The message recognizes the remote method and carries the method arguments as objects. Whenever HTTP is employed as the underlying transport, the HTTP POST message is sent by the client to begin the processing of the SOAP messages.

The server executes the invoked procedure and returns the outcomes as objects in other SOAP message.
