TXMLDocument and TTreeView

I've been tinkering with the idea of using a TTreeView to display the
contents of an XML file.
I can parse the TXMLDocument and add nodes to the tree with no
problems, but it would be really useful if I could attach each node to
the Data property so that I can access it immediately.
The Data porperty is a (System.)Pointer, but the object I use when
traversing the XML Document is a (XMLIntf.)IXMLNode, and I can't work
out how to use these two together.
I tried
tn.Data := addr(iNode);
which worked ok.
Then in my TreeView OnClick method, I want to get the XML node back
again by accessing the Data object, but I can't work out how to do it.
iNode := tn.Data^;
doesn't work, and neither does
iNode := tn.Data^ as IXMLNode;
I guess this is something to do with the fact that IXMLNode is an
interface and I don't really understand how it works.
Can anyone enlighten me, please?
Phil
