Yes Roger, I am aware of that. I inserted 2 comments into your code. One
addressing your problem and the other addressing a common problem
"NEWBIE"'s as you describe in you subject heading come into contact with
on a frequent basis.
If the modification I suggest does not fix your problem please feel free
to mail me personally.
Gareth
PS I insert the comment in the code below again.

This will not work as NdProp is the element node Properties. It has no
siblings. The correct code should ask for the sibling of NdNode.
i.e.
NdNode = NdNode.getFirstSibling();
