<script language="JavaScript" for="window" event="onload">

             xmlDoc.async="false";
             xmlDoc.load("1.xml");
             xmlObj=xmlDoc.documentElement;
             node = xmlDoc.selectNodes("//ROWDATA/RECORDSET/ROW");
             for(i=0;i<node.length;i++)
             {
                 labels=node[i].childNodes[0].text;
                 values=node[i].childNodes[1].text;
                 var obj=document.getElementById("select1");
                 obj.add(document.createElement("OPTION"));
