ABAP and Java mapping

Question

Wanted to confirm my understaing for ABAP and JAVA mapping.
Am I correct in my assumption that these mapping techniques can be used only if input and ouput is in XML format ?
So if XI is receiving a flat comma separated text/non-XML file or an IDOC for that matter and output is NOT in XML format, say again flat text file or IDOC, I cannot use above two techniques?
All the docs I have read suggest that 'Execute' method is called when XML file/data is received, paresed using DOM/SAX/JAXB (for Java mapping) or IXML lib (for ABAP mapping) and then create a output XML file.
-Thanks in advance

Hi Bob,
Here you have a code sample for deescaping. I have have written this code a couple of time ago. The incoming file can be any text format. It might be XML, but not necessarily.
The main method is not reqired, but good for testing.
