Hi,

This does what you want:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

    xmlns:xs="http://www.w3.org/2001/XMLSchema"

    exclude-result-prefixes="xs"

    version="2.0">

    

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

    

    <xsl:variable name="root" select="/"/>

    

    <xsl:template match="/">

        <xsl:call-template name="createChild">

            <xsl:with-param name="childName" select="'Root'"/>

        </xsl:call-template>

    </xsl:template>

    

    <xsl:template name="createChild">

        <xsl:param name="childName"/>

        <xsl:element name="{$childName}">

            <xsl:for-each select="$root//Row[ParentGroupName/text() = $childName]">

                <xsl:call-template name="createChild">

                    <xsl:with-param name="childName" select="GroupName/text()"/>

                </xsl:call-template>

            </xsl:for-each>

        </xsl:element>

    </xsl:template>

</xsl:stylesheet>

Note that this doesn't check for loops. So you can get it stuck if the structure is not tree-like.

Adrian
