Summing a Calculation
I'm trying to get the sum of a purchase order, which seems simple, but I can't find an easy solution. Consider the following XML: <order> <item> <id>1</id> <price>1.34</price> <quantity>4</quantity> </item> <item> <id>2</id> <price>5.77</price> <quantity>3</quantity> </item> <item> <id>5</id> <price>12.99</price> <quantity>1</quantity> </item> </order> I was trying to do something along these lines: <xsl:template match="order"> <xsl:apply-templates select="item"/> <b>Total price: <xsl:value-of select="sum(item/price * item/quantity)"/></b> </xsl:template> To get a total amount for the entire order. But that gives the following error. Can not convert #NUMBER to a NodeList! Before I go down the (seemingly too complex) recursive loop approach, I was wondering if anyone else had another idea. Thanks. - Mark XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
