MS XML Parser

Microsoft has released multiple version's of its XML API because XML has been such a fast changing technology. As of version 4.0, the "MS XML Parser" suite has changed to "MS XML Core Services". The abbreviation is still the same: "MSXML". The MSXML is an API that is used to manipulate the W3C API for XML documents and technologies. Of course MSXML also has non-standard features.

A machine may have one version or multiple versions existing side-by-side. Here are the releases:

Here is an example of how to create an instance of the DOMDocument object in script.

//In JavaScript
var xml = new ActiveXObject("Msxml2.DOMDocument.4.0");
var xsl = new ActiveXObject("Msxml2.DOMDocument.4.0");
xml.load("books.xml");
xml.setProperty("SelectionLanguage", "XPath");
currNode = xml.selectSingleNode("//book/author");

'In VBScript
Dim xml, xsl, currNode
Set xml = CreateObject("Msxml2.DOMDocument.4.0")
Set xsl = CreateObject("Msxml2.DOMDocument.4.0")
xml.load "books.xml"
xml.setProperty "SelectionLanguage", "XPath"
currNode = xml.selectSingleNode("//book/author")

<object runat="server" progid="msxml2.DOMDocument.4.0" id="xObj"> </object>

Earlier versions were instantiated by referencing like:  var source = Server.CreateObject("MSXML2.DOMDocument"); or var xml = new ActiveXObject("Msxml2.DOMDocument.2.6");.

The threading model can be switched from the default of rental model to both-threaded (a.k.a. free-threaded), by prefixing with FreeThreaded. EG: CreateObject("MSXML2.FreeThreadedDOMDocument.4.0").

Here are the various components of the MS XML Parser 4.0 direct from MS [2003-02]:
