RE: [xsl] Transforming a non-hierarchical XML into a hierarchical one

["Michael Kay" <mike@xxxxxxxxxxxx>]

If the sections aren't recursive (different element name used at each level)
then you can do something like

<xsl:for-each-group select="*" 
                    group-starting-with="section">
  <section>
    <h1>...</h1>
    <xsl:for-each-group select="current-group()[position() ne 1]" 
                        group-starting-with="sub-section">
       <h2>...</h2>
          <xsl:for-each-group select="current-group()[position() ne 1]" 
                              group-starting-with="sub-sub-section">
           <h3>...</h3>
