Re: Group various elements with empty tags (flat XML structure to hierarcial XML)

I think the solution is *a lot* simpler, but i read you post in a
diagonal line...

Look the faq for identity transform, it should cover what you need.

I need to convert a flat xml document to something more hierarcial by
surrounding some elements with other empty elements.

Original XML:
------------
<Record>
   <id>102</id>
   <type>O</Type>
   <count>37</count>
   <firstname>Joe</firstname>
   <lastname>Smith</lastname>
   <initial>A</initial>
   <street>35 Main Street</street>
   <city>Moosejaw</city>
   <country>Sasaktchewan</country>
   <postal_code>TOEOPO</postal_code>
   <amount1>1.23</amount1>
   <amount2>4.56</amount2>
   <amount3>7.89</amount3>
   <language>E</language>
</Record>

Desired Output:
--------------
<Record>
   <id>102</id>
   <type>O</Type>
   <count>37</count>
   <NAME>
      <firstname>Joe</firstname>
      <lastname>Smith</lastname>
   </NAME>
   <ADDRESS>
      <street>35 Main Street</street>
      <city>Moosejaw</city>
      <country>Saskatchewan</country>
      <postal_code>TOEOPO</postal_code>
   </ADDRESS>
   <language>E</language>
</Record>

My stylesheet:
-------------
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
    <xsl:template match="node()|@*">
      <xsl:copy>
         <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>

<xsl:template match="Record">
<Record>
   <xsl:apply-templates select="lastname" mode="Name"/>
   <xsl:apply-templates select="postal_code" mode="PC"/>
</Record>
</xsl:template>

<xsl:template match="lastname" mode="Name">
<NAME>
<xsl:apply-templates
select="preceding::firstname[generate-id(following::lastname[1]) =
generate-id(current())]"/>
<xsl:apply-templates select="."/>
</NAME>
</xsl:template>

<xsl:template match="postal_code" mode="PC">
<ADDRESS>
<xsl:apply-templates
select="preceding::street[generate-id(following::postal_code[1]) =
generate-id(current())]"/>
<xsl:apply-templates select="."/>
</ADDRESS>
</xsl:template>

<xsl:template match="Record/*">
<xsl:copy-of select="."/>
</xsl:template>

</xsl:stylesheet>

My output:
--------------
<NAME>
   <firstname>Joe</firstname>
   <lastname>Smith</lastname>
</NAME>
<ADDRESS>
   <street>35 Main Street</street>
   <postal_code>TOEOPO</postal_code>
</ADDRESS>

Can anyone tell me where I have gone wrong? I'm missing <id>, <type> etc,
and my xsl returns only 2 elements when more are sometimes required.

Thanks for your time,
M Glenties
