 1<html>
 2<head>
 3<script event="onload" for="window">   
 4xmldso.XMLDocument.load("cd.xml");   
 5</script>
 6<object classid="clsid:550dda30-0541-11d2-9ca9-0060b0ec3d39" height="0" id="xmldso" width="0">
 7</object>
 8<table>
 9<tr><td><span datafld="name" datasrc="#xmldso" id="test"></span></td></tr>
10</table></head>
11</html>

1<input onclick="alert(document.all('test').innerText);alert(xmldso.recordset.fields('name').value)" type="button" value="value"/>
