I was recently asked if I would provide some insight into solving the following problem. In the given scenario, data stored in flat files in being delivered to the BizTalk message box via a pass-through pipeline. An orchestration subscribes to these messages and creates XML output. Each time a file is processed, the developer wants to 'dump' the contents of the flat file into an element in the output. Other information, including the file name, is also included in the XML.
