Thanks for the advice Dave.
In the end I did get it to work using the code that I posted -
not sure what it was I did that stopped it working before.
Fortunately I don't have to worry too much about scalability
here as this is not a web site but effectively a single-user
application :o)
Thanks
Nick

I haven't tried using that object in a persistent memory scope, but I've
done that with other objects, just for testing. I've been able to do it by
creating the object in the memory scope at the beginning:
<cfobject name="Session.xmlDoc" ...>
I should warn you, however, that it's not a good idea to do this, from a
scalability perspective. You want to release COM objects as quickly as
possible, generally, and might run into some wacky problems if you try to
persist them.
