RE: [xsl] another hierarchical problem

["Michael Kay" <mike@xxxxxxxxxxxx>]

Best approach to this is XSLT 2.0

<xsl:for-each-group select="*" group-starting-with="skill">
  <skill name="{.}">
    <xsl:copy-of select="subsequence(current-group(), 2)"/>
  </skill>
</xsl:for-each>

Having said that, I haven't worked out why your current code doesn't work.
