nextNode()

Is a member of:

XML DOM NodeList
XMLDOMNamedNodeMap

Syntax

set objXMLDOMNode = objXMLDOMNodeList.nextNode()

Remark

This method is used to iterate through either the collection returned from child Node of an element (XMLDOMNodeList collection) or the collection returned from the attributes property of an element (XMLDOMNamedNodeMap collection).

The pointer after returning either of these collections is set to before the first Node in the list. Therefore, when you call the nextNode() method for the first time, it returns the first Node in the list.

As you iterate through this collection, NULL will be returned when the current Node is the last Node or there are no items in the list.

Example

In previous examples, we showed you a similar example of iterating through the Nodes in an XMLDOMNodeList collection:

Dim objDOMDocument As DOMDocument

Dim objXMLDOMNode As IXMLDOMNode

Set objDOMDocument = New DOMDocument

objDOMDocument.async = False

objDOMDocument.Load "http://localhost/xmlcode/people2.xml"

For Each objXMLDOMNode In objDOMDocument.childNodes

`do something with this

¬ Let's change this example to demonstrate using the nextNode property:

Dim objDOMDocument As DOMDocument

Dim objNodeList As IXMLDOMNodeList

Dim objXMLDOMNode As IXMLDOMNode

Set objDOMDocument = New DOMDocument

objDOMDocument.async = False

objDOMDocument.Load "http://localhost/xmlcode/people2.xml"

Set objNodeList = objDOMDocument.childNodes

Set objXMLDOMNode = objNodeList.nextNode

Do Until objXMLDOMNode Is Nothing

' do something with this node

Set objXMLDOMNode = objNodeList.nextNode4

Loop

¬ Get a reference to the XMLDOMNodeList collection.

¬ Fetch the first Node.

¬ Prepare your loop, exiting once the last Node has been fetched.

¬ Fetch the next Node.
