Hi Alex,
You didn't tell us what XSLT version you are using. I try with XSLT 2. Somehow I often have trouble with even rather flat to hierarchical questions. I am sure somebody else can do much better. The below solution works correctly if you add 'level1' to the top of your input xml. If you don't want that, you should adjust the patterns a bit:
<xsl:copy>
<xsl:apply-templates select="current-group()[2]" />
</xsl:copy>
</xsl:for-each-group>
</xsl:template><xsl:template match="*[matches(name(), 'level')]">
<xsl:variable name="currentname" select="name()" />
<xsl:for-each-group
select="current-group()[position() > 1]"
group-starting-with="*[name() = $currentname]"> <xsl:copy>
<xsl:apply-templates select="current-group()[2]" />
</xsl:copy>
</xsl:for-each-group>
</xsl:template>It's a variant to the tree-traversal technique, as it always selects one higher than the current node. Hope this helps, Cheers, -- Abel Braaksma http://xslt.metacarpus.com alex v. wrote: I have a flat xml like this:
