"string-length($Path) != 0" is longhand for just "$Path" (try it)

You want xsl:copy-of, not xsl:value-of, (value-of means 'create a text node
from the string-value of this object, in this case the first node in this 
node-set' ... whereas copy-of means 'copy this node-set')

Then $xpath will be a result tree fragment. To access it as a node-set you
will need to convert it to a node-set by passing it as an argument to the
exsl:node-set() extension function or your XSLT vendor's equivalent extension
function (check the docs).

<xsl:variable name="xp-nodeset" select="exsl:node-set($xpath)"
  xmlns:exsl="http://exslt.org/common" />
