Thanks! It works perfect. Don't believe me, but I haven't found any similar
code in 5 hours of Internet searching... :-)

Thanks very much.

Assuming that the root is identified by iParentID=0 and that in your example
nodes 2 and 4 should be at the same level (since they're both children of
1):

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

<xsl:key name="rowstruct" match="row" use="@iParentID"/>
<xsl:variable name="nbsp">&#xA0;</xsl:variable>

<xsl:template match="/">
    <!-- start with the root -->
    <xsl:apply-templates select="//row[@iParentID=0]"/>
</xsl:template>

<xsl:template match="row">
    <xsl:param name="indent"/>
    <xsl:value-of select="$indent"/><xsl:value-of select="@ItemID"/><br/>
    <xsl:apply-templates select="key('rowstruct', @ItemID)">
        <xsl:with-param name="indent" select="concat($indent, $nbsp)"/>
    </xsl:apply-templates>
</xsl:template>

</xsl:stylesheet>


Hope this helps,
Alex
