How can I get the sum() ???

[Eric Chow <ec...@macaucabletv.com>]

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 !!!

That's an XSLT question, a FAQ in fact. Check the XSL FAQ and
the XSL list:

You need a recursive template to cover the general case, something
like
