This is an University project which aim was to provide transformation from HL7 medical data format to flexibly 
configured XML.

It starts a scheduler which listens for input files in specified directory and executed the transformer every x seconds.
The results are stored in a separate directory.
The XML element and attribute names can be adequatly set in the configuration file. 

An example of application results can be find below (data was anonimized).
