Please note that every item under level2 becomes a step2 in my output XML. You have not really spelled out whether there can be more elements like level2. Assuming there can be more like e.g. in <root> <level1> <st1> <desc><text>sample desc</text></desc> <!-- A <spec> element can occur here as well--> <level2> <item><text>r1 </text></item> <item><text>r2</text></item> </level2> <spec><para>Some spec 1</para></spec> <spec><para>Some spec 2</para></spec> <level2> <item><text>r3 </text></item> <item><text>r4</text></item> </level2> <spec><para>Some spec 3</para></spec> <spec><para>Some spec 4</para></spec> </st1> </level1> </root> and you want to transform that into e.g. <root>
<step1>
<text>sample desc</text>
<step2>
<text>r1 </text>
</step2>
<step2>
<text>r2</text>
<spec>
<para>Some spec 1</para>
</spec>
<spec>
<para>Some spec 2</para>
</spec>
</step2>
<step2>
<text>r3 </text>
</step2>
<step2>
<text>r4</text>
<spec>
<para>Some spec 3</para>
</spec>
<spec>
<para>Some spec 4</para>
</spec>
</step2>
</step1>
</root>then you can change the stylesheet posted earlier to use XSLT 2.0 grouping as follows: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0"> <xsl:output indent="yes"/> <xsl:strip-space elements="*"/> <xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template> <xsl:template match="st1/desc | st1/level2">
<xsl:apply-templates/>
</xsl:template> <xsl:template match="level1">
<step1>
<xsl:for-each-group select="st1/*" group-starting-with="level2">
<xsl:apply-templates select="."/>
</xsl:for-each-group>
</step1>
</xsl:template> <xsl:template match="level2/item">
<step2>
<xsl:apply-templates/>
</step2>
</xsl:template> <xsl:template match="level2/item[last()]" priority="3">
<step2>
<xsl:apply-templates/>
<xsl:copy-of select="current-group()[self::spec]"/>
</step2>
</xsl:template><xsl:template match="st1/spec"/> </xsl:stylesheet> -- Martin Honnen http://msmvps.com/blogs/martin_honnen/
