Re: Another problem from Flat XML File to Hierarchical

<xsl:template match="/">
   <xsl:for-each-group
       select="$data/*"
       group-starting-with="level1">

       <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>

I have a flat xml like this:

<level2></level2>
<level3></level3>
<level2></level2>
<level1></level1>
<level2></level2>
<level3></level3>
<level3></level3>

and I need to transform in a hierarchy structure like this using the
tag name as key:

<level2>
<level3></level3>
</level2>
<level2></level2>
<level1>
<level2>
<level3></level3>
<level3></level3>
</level2>
</level1>

Thanks in advance.
