Hello, How can I get the sum() of two fields ?? <orders> <order> <item>Book</item> <price>29.9</price> <qty>3</qty> </order> <order> <item>CD</item> <price>10.5</price> <qty>5</qty> </order> </orders> I want to get the subtotal of the above order.xml, which result should be (29.9*3 + 10.5*5) !!! I tried sum("/orders/order/price*/orders/order/qty"), but failed !!!
