This is one of the base objects of the DOM. Most of the other DOM objects inherit this object; therefore, you will see a lot of properties and methods repeated in each of these objects.
These objects are:
- DOMDocument
- XMLDOMAttribute
- XMLDOMCDATASection
- XMLDOMComment
- XMLDOMDocumentFragment
- XMLDOMDocumentType
- XMLDOMElement
- XMLDOMEntity
- XMLDOMEntityReference
- XMLDOMNotation
- XMLDOMProcessingInstruction
- XMLDOMText
- XTLRuntime
Although all these objects inherit methods and properties from the XMLDOMNode object, they will all also have properties and methods that are unique to their function. For example, the XMLDOMElement object has extra methods for obtaining attribute information. The XMLDOMNode interface provides just the basic information, like the name of the Node, its text, etc.
To know which type of Node is currently being accessed, the nodeType property returns which type of Node you are referencing when using the XMLDOMNode object, which is explained in detail later in this chapter under the nodeType property.
Also, see the docType property for more information on Dual interfaces. This explains how to cast from one type of object to the other.
The following example is the same as the example from the XMLDOMElement, except it now uses the XMLDOMNode object to return the root element of the XML file from a
DOMDocument.
Dim objDOMDocument As DOMDocument
Dim objXMLDOMElement As IXMLDOMNode
Set objDOMDocument = New DOMDocument
objDOMDocument.async = False
objDOMDocument.Load "http://localhost/xmlcode/people2.dtd"
Set objXMLDOMNode = objDOMDocument.documentElement
