Iterators, Enumerations and Arrays

I'm trying to write an extension for Java XSLT Engines (primarily Saxon 
and Xalan) in have a java class which I access using the generic "java:" 
namespace, I need to iterate over both an Enumeration and an Array to 
produce a node-set. I'd like to do this without having to directly use 
any classes of Xalan or Saxon.

Is there a way I can either produce a nodeset in my java class? Or is it 
possible to pass back a org.w3c.Node and have it used to produce a nodeset?

Or can I somehow iterate over the array or Enumeration inside my 
<func:function...> elements?

thanks
Mark
