Re: [xsl] Creating multi-level groupings

I hope the following XSL would help ..

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

<xsl:output method="html" indent="yes"/>

<xsl:key name="by-prod_doctype_cust" match="doc"
use="concat(normalize-space(../text()), ' ' ,
doc_type, ' ', customer)"/>

<xsl:template match="/">
  <html>
    <head>
      <title/>
    </head>
    <body>
      <table border="1">
	<xsl:for-each select="volume/product/doc[count(. |
key('by-prod_doctype_cust', 
concat(normalize-space(../text()), ' ' , doc_type, '
', customer))[1]) = 1]">
	   <tr>
	     <td>
	       <xsl:value-of
select="normalize-space(../text())"/>
	     </td>
	     <td>
	       <xsl:value-of select="doc_type"/>
	     </td>
	     <td>
	       <xsl:value-of select="customer"/>
	     </td>
	   </tr>
	   <xsl:for-each select="key('by-prod_doctype_cust', 
concat(normalize-space(../text()), ' ' , doc_type, '
', customer))">
	     <tr>
	       <td/>
	       <td>
		 <xsl:value-of select="id"/>
	       </td>
	       <td>
		 <xsl:value-of select="title"/>
	       </td>
	     </tr>
	   </xsl:for-each>
	</xsl:for-each>
      </table>
    </body>
  </html>
</xsl:template>

</xsl:stylesheet>
