[xsl] Extracting Unique Nodes

["Subramanian, Veera" <Veera_Subramanian at standardandpoors dot com>]

Hi,
   Iam finding it difficult to extract distinct nodes from XML. Please see the sample xml below.

<?xml version="1.0"?>
<page>
  <data>
     <ASOF_DT>1</ASOF_DT>
     <ASOF_DT>1</ASOF_DT>
     <ASOF_DT>3</ASOF_DT>
     <ASOF_DT>5</ASOF_DT>
  </data>
  <data1>
     <ASOF_DT>5</ASOF_DT>
     <ASOF_DT>5</ASOF_DT>
     <ASOF_DT>7</ASOF_DT>
  </data1>   
</page>

How can i write an xpath expression to extract distinct asof_dt under <data> & <data1> seperately.

Picking distinct list under data , should bring 1,3,5
Picking distinct list under data1 , should bring 5,7
 

Regards
Veera
