how to find the MSXML version?

Hi,

 

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.

 

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 Msxml2.DOMDocument.4.0 is obsolete, don't use it.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.

     

    So, this should be enough:

    // JScript
var xmlDOM = Sys.OleObject("Msxml2.DOMDocument.6.0");

    But if you want a fallback use something like:

    // JScript
    function 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 < progIDs.length; i++) {
    try {
      var xmlDOM = Sys.OleObject(progIDs[i]);
      return xmlDOM;
    }
    catch (ex) { }
  }     
  return null;
}
