XMLDeliveryChannel for Complex Data Type

Hi,

I am using XML Delivery Channel dll to transfer PI data from PI System to Webservices.

I could able to transfer data for one record in single http request from PI system to webservice successfully.

But my requirement is  to transfer mutiple record simultaneously in one single http request.

May be this is example of complex data type. 

so My question is how to transfer data for complex data type using XML Delivery channel ?

Could anyone please help me to explain me how to do this?

Thanks
