How to insert data using XML in SQL Server 2008 - sql-server

Question

The whole "inserting multiple records with XML" has pretty much been superseded by table parameters in SQL Server 2008.
CREATE PROCEDURE [Booking].[PlannerQuotation]

#ResponseXML XML OUTPUT)

I use SQL Server 2008 in my web application back end. Apparently I iterate through all the records from the C# code whenever there is a multiple insertion scenario. I have never tried the multiple insert using XML. And I think after reading many blogs about XML manipulation using SQL Server 2008 the process is pretty tedious ..
So my question is: is inserting via XML more efficient than the traditional inserts?
