Use modify() Method (xml Data Type) with insert (XML DML).

update YourTable
set xmlData.modify('insert <customerId display="CID">123</customerId> 
                    into customer[1]')
where xmlData.exist('/customer/customerId') = 0

Use exist() Method (xml Data Type) in the where clause so you only update the rows that does not have a customerId node.
