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

In 3.0, apart from xsl:iterate as suggested by John Lumley, you could consider
using a fold:

<xsl:function name="f:wrap" as="element(*)">
  <xsl:param name="e" as="element(*)"/>
  <xsl:param name="n" as="xs:string"/>
  <xsl:element name="{$n}"><xsl:copy-of select="$e"/></xsl:element>
</xsl:function>

then

fold-left(reverse(tokenize($path, '/')), $stuff-from-somewhere-else,
f:wrap#2)
