Re: XSLT 2: Best Way to Synthesize Elements Given List

I'd suggest this non-recursive solution:

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:param name="pPath" select="'/foo/bar/baz/bam/bak/bap/bah/baw'"/>

 <xsl:variable name="vNames" select="tokenize($pPath, '/')[.]"/>

  <xsl:template match="*[count(current()/ancestor::*) lt count($vNames)]">
    <xsl:element name="{$vNames[count(current()/ancestor::node())]}">
      <xsl:apply-templates select="*"/>
    </xsl:element>
  </xsl:template>

  <xsl:template match="text()"/>
</xsl:stylesheet>


When applied on:

<x1>
 <x2>
  <x3>
   <x4>
    <x5>
     <x6>
      <x7>
       <x8>
        <x9>
         <x10>
          <x11>
           <x12>
            <x13>
             <x14>
              <x15>
               <x16>
                <x17>
                 <x18>
                  <x19>
                   <x20>
                   </x20>
                  </x19>
                 </x18>
                </x17>
               </x16>
              </x15>
             </x14>
            </x13>
           </x12>
          </x11>
         </x10>
        </x9>
       </x8>
      </x7>
     </x6>
    </x5>
   </x4>
  </x3>
 </x2>
</x1>

the result is:

<foo>
   <bar>
      <baz>
         <bam>
            <bak>
               <bap>
                  <bah>
                     <baw/>
                  </bah>
               </bap>
            </bak>
         </bam>
      </baz>
   </bar>
</foo>
