## 11.23.2 CGIXMLRPCRequestHandler

The `CGIXMLRPCRequestHandler` class can be used to handle XML-RPC requests sent to Python CGI scripts.

`register_function`( | function[, name])

  Register a function that can respond to XML-RPC requests. If name is given, it will be the method name associated with function, otherwise function.__name__ will be used. name can be either a normal or Unicode string, and may contain characters not legal in Python identifiers, including the period character.

`register_instance`( | instance)

  Register an object which is used to expose method names which have not been registered using `register_function()`. If instance contains a `_dispatch()` method, it is called with the requested method name and the parameters from the request; the return value is returned to the client as the result. If instance does not have a `_dispatch()` method, it is searched for an attribute matching the name of the requested method; if the requested method name contains periods, each component of the method name is searched for individually, with the effect that a simple hierarchical search is performed. The value found from this search is then called with the parameters from the request, and the return value is passed back to the client.

`register_introspection_functions`( | )

  Register the XML-RPC introspection functions `system.listMethods`, `system.methodHelp` and `system.methodSignature`.

`register_multicall_functions`( | )

  Register the XML-RPC multicall function `system.multicall`.

`handle_request`( | [request_text = None])

  Handle a XML-RPC request. If request_text is given, it should be the POST data provided by the HTTP server, otherwise the contents of stdin will be used.

Example:

    class MyFuncs:
        def div(self, x, y) : return div(x,y)

    handler = CGIXMLRPCRequestHandler()
    handler.register_function(pow)
    handler.register_function(lambda x,y: x+y, 'add')
    handler.register_introspection_functions()
    handler.register_instance(MyFuncs())
    handler.handle_request()
