Re: Document summary using xsl:key

Hi Rob,
Please try this slightly modified XSL..

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes"/>
  <xsl:key name="x"
match="Invoice/InvoiceLineItem/MonetaryAdjustment/TaxAdjustment"
use="@Code"/>

  <xsl:template match="Invoice">
    <summary>
      <xsl:apply-templates
select="InvoiceLineItem/MonetaryAdjustment/TaxAdjustment"
/>
    </summary>
  </xsl:template>
      
  <xsl:template
match="InvoiceLineItem/MonetaryAdjustment/TaxAdjustment">
    <xsl:if test="generate-id(.) =
generate-id(key('x', @Code)[1])">
	<xsl:variable name="N" select="@Code"/>
	<xsl:variable name="R"
select="TaxPercent/MeasurementValue"/>
	<xsl:variable name="C"
select="count(/Invoice/InvoiceLineItem/MonetaryAdjustment/TaxAdjustment[@Code
= $N])"/>
	<xsl:variable name="V"
select="sum(/Invoice/InvoiceLineItem/MonetaryAdjustment/TaxAdjustment[@Code
= $N]/TaxValue)"/>
	<tax code="{$N}" count="{$C}" rate="{$R}"
tax="{$V}"/>
   </xsl:if>
</xsl:template>
</xsl:stylesheet>

Regards,
Mukul
