Have known AJAX for a very long time. But here I still want to write it down about how to create DOM Document at Client side.

1. document.implementation which is supported by Mozilla, Netscape etc
2. ActiveObject which is provided by MS

If you are using Mozilla, write code like this:

if (document.implementation && document.implementation.createDocument) {
  xmlDocument  =  document.implementation.createDocument('','', null );
}

xmlDocument  =   new  ActiveObject( " MSXML.DOMDocument " );

Here list down the versions of MSXML:

MSXML.DOMDocument
MSXML2.DOMDocument
MSXML3.DOMDocument
MSXML4.DOMDocument
Microsoft.XmlDom
