hello, I am haveing a problem with a XSL file. I am trying to add up all the quanties of each of the items and compile a shopping list. here is some of my xml file
<menu>
<recipe>
<head>
<title>$20,000 Prize-Winning Chili</title>
</head>
<ingredients>
<ing>
<amt>
<qty>2.5</qty>
<unit>pound</unit></amt>
<item>Lean ground chuck</item></ing>
<ing>
<amt>
<qty>1</qty>
<unit>pound</unit></amt>
<item>Lean ground pork</item></ing>
<ing>
<amt>
<qty>1</qty>
<unit>cup</unit></amt>
<item>Finely chopped onion</item></ing>
<ing>
<amt>
<qty>4</qty>
<unit/></amt>
<item>Garlic cloves; finely chpd.</item></ing>
</menu>
The full XML file is located here (site down) I want it to list all the items once(if they come up more than that) and give the sum of the quanty(the qty tag). eg(quanty to come form qty tag): Chicken 400g
Milk 100ml
My XSL code: (full listing (site down))
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xslutput method="html"/>
<xsl:key name="tempItem" match="recipeml/menu/recipe/ingredients/ing" use="item"/>
<xsl:template match="/">
<xsl:apply-templates select="recipeml/menu"/>
</xsl:template>
<xsl:template match="menu">
<html>
<head>
<title>Shopping List</title>
</head>
<body>
<xsl:apply-templates select="//ing"/>
</body>
</html>
</xsl:template>
<xsl:template match="//ing">
<li>
Item:
</li>
<xsl:for-each select="./item[generate-id()= generate-id(key('tempItem',item)[1])]">
<xsl:value-of select="./item"/>
Count: <xsl:value-of select="count(/item=current())"/>
Generated ID: <xsl:value-of select="generate-id(.)"/>
</xsl:for-each>
</xsl:template>
<xsl:template match="*|text()"/>
</xsl:stylesheet>
