Can anyone give solution for this?

I have the data like this..

<product code="pen">
<pen rate="1.23" points="0"/>
<pen rate="1.15" points="0"/>
<pen rate="1.68" points="6"/>
<pen rate="1.94" points="2"/>
<pen rate="1.23" points="0"/>
<pen rate="1.00" points="0"/>
</product>
<product code="Book">
<pen rate="1.23" points="0"/>
<pen rate="1.15" points="0"/>
<pen rate="1.68" points="0"/>
<pen rate="1.94" points="0"/>
<pen rate="1.23" points="0"/>
<pen rate="1.00" points="0"/>
</product>


My output should come like this..

Pen
rate points
1.23 0
1.15 0
1.68 6
1.94 2
1.23 0
1.00 0

Book
rate points
1.23 0
1.15 0
1.68 0
1.94 0
1.23 0
1.00 0

In the product - Book, all the points values are "0". So we dont want to show the Points column in the output when points=0.

We need to display point column when any of the points != "0"

For quality XSL consulting contact jbampton@gmail.com with XSL as the subject.

The solution based on html is:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:template match="/">
<html>
<head></head>
<body>
<xsl:for-each select="products/product">
<table>
<tr>
<td>
<xsl:value-of select="@code"></xsl:value-of>
</td>
<xsl:if test="sum(pen/@points) != 0 ">
<td></td>
</xsl:if>
</tr>
<tr>
<td>
rate
</td>
<td>
<xsl:if test="sum(pen/@points) != 0 ">
points
</xsl:if>
</td>
</tr>
<xsl:for-each select="pen">
<tr>
<td>
<xsl:value-of select="@rate"></xsl:value-of>
</td>
<xsl:if test="sum(@points + sum(preceding-sibling::pen/attribute::points) + sum(following-sibling::pen/attribute::points)) != 0 ">
<td>
<xsl:value-of select="@points"></xsl:value-of>
</td>
</xsl:if>
</tr>
</xsl:for-each>
</table>
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>


There probably is an easier way but this is what I hacked together in 5 minutes. Let me know if you want that in XSL-FO format
