An XML document is a collection/hierarchy of objects (nodes) that are
usually accessible through the standardized DOM (Document Object Model)
API. You can pass object references to Jess (see documentation).
Your options then range from pure Jess script to (almost) pure Java:
1) Within your Jess script you can call a Java object's methods. Thus, you
can also modify your XML document from within a deffunction or directly on
the RHS.
2) You can write Jess Userfunctions (in Java) that perform the necessary
modifications. You'd use these Userfunctions in your script.
3) You can write a normal Java class that performs the modifications. You'd
call its method(s) the usual way.
Greetings, Thomas
