hi bjoren-thanks for your explanations,
i still  didn't find the way implement it so the output xml will be exactlly 
as i described earlyer - my code should create exactlly the same xml!!!this 
is the demand in this case
the problem is still-how can i add the "address" element with no namespace 
(the xmlns namespace) ?
when i am using the 'CreateNode' method as you advised me i get the address 
elenemt with the same namespce as it's parent(the 'employee')
if you can send me the correct code it will be helpfull
thanks again
stanley
