 When creating and consuming Web services in Internet Explorer, you need to be familiar with XML and operations on XML. In particular, you need to know how to load an XML file from a JavaScript script, and how to manipulate the data loaded into the browser. The data read from an XML file is arranged in Internet Explorer's memory as an object, the DOMDocument object. This DOMDocument object has 35 properties, 25 methods, and 3 events. With this object, you can load XML files, navigate the document graph model, query nodes of the graph, etc. The first thing you need to do is to create an empty object. You do it with the ActiveXObject creator:

xmldoc = new ActiveXObject("Msxml2.DOMDocument.3.0");
You load an XML file with the load() method:

xmldoc.load("mydvd.xml");
The following script loads an XML file and prints its content to an alert box:

<SCRIPT LANGUAGE="JavaScript">
<!--
  var xmldoc=new ActiveXObject("MSXML2.DOMDocument.3.0");
  xmldoc.load("mydvd.xml");
  alert(xmldoc.documentElement.xml);
// -->
</SCRIPT>
Try it in IE. You should get the XML file echoed back in an alert box.
