RE: [xsl] when to use 'as' attribute on a variable

2006-03-08 07:10:13
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.
