If $mypath is a string, you'll need to use dyn:evaluate from EXSLT or whatever equivalent you can find for your interpreter.

if $mypath is a nodeset defined by an XPath, e.g.

<xsl:variable name="myPath" select="a/b/c"/>
then I think you might be able to do something like this:

<xsl:template match="$myNodeSet>
  <xsl:apply-templates select="$myPath"/>

in that case it's wonky but xslt doesn't like to have two variables in the same xpath AFAICT.

For the life of me, I don't know how to do this even
though it seems like it would be very easy.

I have a variable, myNodeSet, which points to a node set,
in this case a set of 1 document element node.
I have another variable, myPath, which reflects a
(relative) location path to nodes I want to select from

This works:
 <xsl:variable name="t1" select="$myNodeSet//a/b/c"/>

This doesn't:
 <xsl:variable name="t2" select="$myNodeSet/$myPath"/>

I'm using MSXML 4.0 and it's complaining with:
 NodeTest expected here.
which makes sense.

How do I filter down my node-set based upon some variable
location path?
