how to find the MSXML version?

Question

Hi,&nbsp;I am developing a script extension for testcomplete. I want to know if there is a way to find aout wich MSXML version is installed on the maschine.&nbsp;Because the command "Sys.OleObject('Msxml2.DOMDocument.4.0')" throws me an error. Is there a way to ask inside the script extension code to check if MSXML4 is installed or MSXML6 a.s.o.?

Use Msxml2.DOMDocument.6.0 - it's included in all Windows versions since Windows XP SP3. Msxml2.DOMDocument.4.0 is obsolete, don't use it. If you want a fallback, use Msxml2.DOMDocument.3.0 as an alternative.
&nbsp;
So, this should be enough:
// JScript
var xmlDOM = Sys.OleObject("Msxml2.DOMDocument.6.0");
But if you want a fallback&nbsp;use something like:
// JScriptfunction Test(){  var xmlDOM = GetXMLDOMDocument();  if (xmlDOM != null) {    // Do something  }  else  {    // Neither MSXML 6 nor MSXML 3 was found - something's wrong with the computer  }}
function GetXMLDOMDocument()
{
  var progIDs = ['Msxml2.DOMDocument.6.0', 'Msxml2.DOMDocument.3.0'];
  for (var i = 0; i &lt; progIDs.length; i++) {
    try {
      var xmlDOM = Sys.OleObject(progIDs[i]);
      return xmlDOM;
    }
    catch (ex) { }
  }     
  return null;
}
