Re: [xsl] Merge? Copy?

[Mukul Gandhi <mukul_gandhi@xxxxxxxxx>]

This is a grouping problem, and can be solved using
Muenchian grouping -

<?xml version="1.0"?> 
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
 
<xsl:output method="xml" indent="yes" /> 

<xsl:key name="by-customer" match="Customer" use="@id"
/>
 
<xsl:template match="/Customers">
  <Customers>
    <xsl:for-each select="Customer[generate-id(.) =
generate-id(key('by-customer',@id)[1])]">
      <Customer id="{@id}">
        <Name>
          <xsl:value-of select="Name" />
        </Name> 
        <Address>
          <xsl:value-of select="Address" />
        </Address>
        <xsl:for-each select="key('by-customer',@id)">
          <Sales> 
	    <date>
	      <xsl:value-of select="Sales/date" />
	    </date> 
	    <amount>
	      <xsl:value-of select="Sales/amount" />
	    </amount> 
	  </Sales>
        </xsl:for-each>
      </Customer>
    </xsl:for-each>
  </Customers> 
</xsl:template>
  
</xsl:stylesheet>
