Re: perl RPC::XML (blackperl)

>Am I really coming at this backwards?

I don't know if it's you, but somebody is coming at this backwards.  You don't
specfify an XML-RPC API with an XML document and have users reverse engineer
it.  The API in question should be documented something like this:

  Method name: "Gateway.SendMessage"
  One parameter, of type structure.  Members:

    Service: type integer, meaning: ... example: 0
    Password: type string, meaning: ... example: "aPassword"
    Text: type string, meaning: ... example: "A demonstration short message"
    DeliveryTime: type datetime, meaning: ... example: April 21, 2005 ...
    

Anyway, the way you specify RPC parameters is to add each as an argument to
your $client->send_request().  You need one parameter, so your
$client->send_request will have two arguments.  That one parameter is a
structure, which is represented in XML::RPC by a XML::RPC::struct.  The
constructor for XML::RPC::struct (see perldoc XML:RPC) takes a Perl hash
reference as its argument.  Since a Perl hash and an XML-RPC structure are
virtually identical data structures, it's easy to see the correspondence, with
the one complication that the hash values are references to XML::RPC data
objects, not the normal Perl data structures.  The Perl hash you start with is
thus something like

  ('Service'  => new RPC::XML::int(0),
   'Password' => new RPC::XML::string('aPassword'),
   'Text'     => new RPC::XML::string('A demonstration short message'),
   ...)
