To store an external XML doc in a variable am I right in
saying I should
use document-node() ?
yes
So what advantage does document-node() give me over
element(), node(), or
item()??
It's more specific, and it therefore makes your code more robust. If you
write a function that's designed to process document nodes, and you call it
with an element node, then if the function signature says document-node()
you will get an error, but if it says node() then you won't.
