Add XML / SOAP Decoding to Existing HTTP Decode Program

We have some java code which reads in a WireShark formatted trace and decodes it into a text format. We need to add XML / SOAP / WSDL decoding to it. This is only one module which is needed and can be easily added to the module which already does HTTP decoding. I am attaching a sample input WireShark trace and the text file that is created. The decoding should be basically similar to how WireShark does it. There may need to be some enhancements if WireShark decoding is not good.
