<script>
function loadXML(xmlString) { 
  var xmlDoc = null; 
  if (!window.DOMParser && window.ActiveXObject) { 
    var xmlDomVersions = ['MSXML.2.DOMDocument.6.0', 'MSXML.2.DOMDocument.3.0', 'Microsoft.XMLDOM']; 
    for (var i = 0; i < xmlDomVersions.length; i++) { 
      try{ 
        xmlDoc = new ActiveXObject(xmlDomVersions[i]); 
        xmlDoc.async = false; 
        xmlDoc.loadXML(xmlString); 
        break; 
      } 
      catch (e) { 
      } 
    } 
  }
