This was exactly what I needed...
var dtpth = getAttribute('datapath');
var xp = dtpth.getAttribute('xpath');
Debug.write("xp = "+xp);
...

This is an example of getting a string value of the
datapath for the grid. I hope this helps.
<grid bgcolor="0xFFFFFF" width="${parent.width}"

datapath="dsStanorde:/yrtotals">

datapath="to_yyyymm/text()" style="silvercolors"
editable="false">To Year/Mth</gridtext>
<gridtext

var
dtpth = getAttribute('datapath');
var xp
= dtpth.getAttribute('xpath');
Debug.write("xp = "+xp);
</method>
</grid>
