Well... I guess you could just iterate over the tree nodes and recurse  
down into the various branches, adding nodes to the DOM (the XML  
document object). So something like:

	require ''fox16''
	require ''rexml/document''

	...

	def add_subtree_for(tree_item, node)
		tree_item.each do |child|
			e = Element.new(''node'')
			e.add_text(child.text)
			node.add_element(e)
		end
	end

	def dump_as_xml(tree_list)
		doc = REXML::Document.new
		tree_list.each do |tree_item|
			e = Element.new(''node'')
			e.add_text(tree_item.text)
			doc.root.add_element(e)
			add_subtree_for(tree_item, e)
		end
	end

Note that this is completely untested code, that I''ve just made up on  
the spot! I''m assuming you have some more specific format and end use  
in mind. Regardless, this is probably the sort of pattern that you''ll  
follow.

Hope this helps,

Lyle
