If you need repeatedly to find nodes given some value, then keys are the right answer. You haven't explained your problem well enough to know whether this applies. Think of keys as follows: if you want (repeatedly) to find the employee with a given employee number, then "match" should be a pattern than matches employees, and "use" should be an XPath expression which, starting from an employee element, returns the employee number. Give the key an arbitrary name K, and you can then find the employee whose number is $emp-nr as key('K', $emp-nr).
