You can use try/catch e.g.
   var xmlDocument;
   try {
     xmlDocument = new ActiveXObject("Msxml2.DOMDocument.5.0");
   }
   catch (e) {
     try {
       xmlDocument = new ActiveXObject("Msxml2.DOMDocument.4.0");
     }
     catch (e) {
       xmlDocument = new ActiveXObject("Msxml2.DOMDocument.3.0");
     }
   }

Msxml2.DOMDocument is bound to Msxml2.DOMDocument.3.0 or earlier as 
MSXML 4 and 5 only use version specific program ids.
