Bulk Loading XML into SQL Server 2005 using .NET

With a number of clients, I have been provided a sample format for a transactions along with instructions to develop a process to load it into a database as quickly and painlessly as possible. This usually comes with the requirements that the XML data file can have any number of records from 1 to n. This example demonstrates the most efficent and scalable way that I have found to solve this. Not to mention that it can be maintained without rebuilding the solutions each time the data format changes.
