Roy,

I played around with your example, but it doesn't seem to work when I
have multiple xyzzy elements, for example:

<foo>
  <bar>
    <xyzzy>
      <int>3</int>
    </xyzzy>
    <xyzzy>
      <int>4</int>
    </xyzzy>
    <xyzzy>
      <int>5</int>
    </xyzzy>
  </bar>
  <nodeset>
    <node>
      <str>wrong (1)</str>
      <int>3</int>
    </node>
    <node>
      <str>wrong (2)</str>
      <int>2</int>
    </node>
    <node>
      <str>right (3)</str>
      <int>1</int>
    </node>
  </nodeset>
</foo>

I'm wondering if it's not possible to do what I'm trying to do.
