The LoadNewNode() Function
The InsertFirst(), InsertLast(), InsertBefore(), and InsertAfter() functions must
retrieve information about the new CD from the text area. This is done by calling
the LoadNewNode() method. The LoadNewNode() method loads information about
the new CD from the text area into the DOM parser and then returns a reference to
the root node of the information about the new CD to one of the four functions that
called it. Here’s the LoadNewNode() method:
function LoadNewNode()
{
var xmlNewNode = document.all("newnode").value;
var objNewNode = new ActiveXObject("MSXML2.DOMDocument.4.0");
objNewNode.async = false;
objNewNode.loadXML(xmlNewNode);
if (objNewNode.parseError.errorCode != 0)
{
alert("Error loading new node: " + objNewNode.parseError.reason);
return null;
}
