Please Help me on Nested Complex structures

Hello all, I am newbie..and if i sound stupid, excuse me I have downloaded PEAR SOAP and started going through the tutorials available on net.Then i started to see various examples provided in SOAP/example. We have a requirement to pass a very Complex structure. Then I tried to implement your wsdl_client.php.I have also seen example_server.php and server.php. I need to pass say ,structure B in another structure A and then pass structure A in my function call...how would this affect the entire scenario??(i mean, the way client should send this Struct A, and the way typedef and dispatch_map changes in server) I am getting stuck at various points i) How would a client send a complex structure while making a call to the service(as shown below..Nested Structures) ii)Then how would the typedef & typedef change , since i need a structure within a structure I need like this, <MyExample> (stuct A) <MyName>XYZ</MyName> { <MyAddr> (struct B) <HNO>###</HNO> { <CITY>ABC</CITY> } </MyAddr> </MyExample> } I will be really obliged if anyone can help me out , Thanks a Lot , Siddarth.
