That's very clever. I'm not sure it's clearer than my current recursive
solution though :-)
Why, this is non-recursive, 10-lines transformation that contains just
two XPath expressions, not counting the tokenization -- the template
match pattern and the indexing of the tokens to get the current
element-to-construct name.
Also, as an added benefit, one could experiment with the used XML
document's depth, to reveal what the limits of their XSLT
processor/XML-parser are :)

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>

</x10>
</x9>
</x8>
</x7>
</x6>
</x5>
</x4>
</x3>

the result is:

<bak>

<baw/>
</bah>
</bap>
</bak>
</bam>

Say I have this string: "foo/bar" (or any arbitrarily-long sequence of
/-delimited tag names) and want to construct from it:
<foo>
<bar>
<!-- Stuff added here that I get from somewhere else -->
</bar>
</foo>
Is there an easier or more obvious way to generate this than an
recursive
function?
With a recursive function I can easily create child elements until the
sequence is exhausted but it feels like there should be an easier way
using XSLT 2 but if there is I'm not thinking of it.
