The first question is, what are your criteria for deciding which
is the right value?

Right now the value of the PortPath variable is a nodeset including
all nodes that match //PORTPATH.  The first of these, in document
order, is /REGISTER_STOR/PORTPATH.  Depending on how you use $PortPath
in an expression, you will probably get only this first one.

If what you want is the PORTPATH at the top level, then use

  <xsl:variable name="PortPath" select="/PORTPATH"/>

However that's going by your XML snippet, which is not a well-formed
XML document (it has more than one top-level element).
So it's possible that what you really want is select="/*/PORTPATH"...
it depends on what your input XML document really looks like,
and what your design specification is for which PORTPATH is
the one that matters.
