SOAP, WSDL, Lit+Documents and multi-node lists

Hi all, I'm currently in the middle of integrating a .NET SOAP service into a client's site. The service has WSDL files for all the services so I create a soap client thus: $wsdl = new SOAP_WSDL('http://www.example.com/Service.asmx?wsdl') $client = $wsdl->getProxy(); I have used the resulting $client without problem, except now. I need to pass parameters to a method in some way so that the client will create the following snippet of xml in the soap request: <Requests> <RoomRequest> <RoomID>1</RoomID> <NumRooms>3</NumRooms> </RoomRequest> <RoomRequest> <RoomID>2</RoomID> <NumRooms>1</NumRooms> </RoomRequest> </Requests> I can get one of the room requests from this structure: $requests['RoomRequest'] = array("RoomID" => 1, "NumRooms" => 3); But I cannot get more than one to appear, $requests[0]['RoomRequest'] and $request[1]['RoomRequest'] result in extra <item> tags round each <RoomRequest> tag. If it helps at all the WSDL file is located at: http://tkl.mars-on-the-net.com/marsserver/Hotels.asmx?wsdl and I'm trying to call the BookRooms method which takes an array of RoomRequest. Is there another approach I should be using? I had thought about trying DOM to build the xml and I've also tried passing in a string containing all the xml as the only parameter but this just resulted in &lt; and &gt; littered throughout. Cheers, Paul.
