NIST If the "newChild" is already in the tree, the "insertBefore(newChild,refChild)" method must first remove it before the insertion takes place. Insert a node Element ("employeeId") that is already present in the tree. The existing node should be removed first and the new one inserted. The node is inserted at a different position in the tree to assure that it was indeed inserted.
