Re: De-flattening an XML tree

I have a special solution for your problem:

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

<xsl:key name="data" match="data"
use="generate-id(preceding-sibling::record[1])"/>

<xsl:template match="recordset">
    <xsl:copy>
        <xsl:apply-templates select="record"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="record">
    <xsl:copy>
        <xsl:apply-templates select="key('data',generate-id())"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="data">
    <xsl:copy/>
</xsl:template>
</xsl:stylesheet>

This should give you the hints for deflattening XML. But there are much more
generic stylesheets available in the archives.
