I think you've misunderstood. By changing the result format from the default of object to e4x, you _avoid_ the problem the OP had, which is if there is only one object returned, you get a different result than if you have multiple objects returned. You don't have to trap for the problem, because it goes away. If there is only one node, you get one node. If there are multiple nodes, you get multiple nodes. But whatever. -Amy
