XML.lastChild

Availability

Flash Player 5.

Usage

my_xml.lastChild:XMLNode

Description

Read-only property; an XMLNode value that references the last child in the node’s child list. The

XML.lastChild property is null if the node does not have children. This property cannot be

used to manipulate child nodes; use the

appendChild(), insertBefore(), and removeNode()

methods to manipulate child nodes.

Example

The following example uses the XML.lastChild property to iterate through the child nodes of an

XML node, beginning with the last item in the node’s child list and ending with the first child of

the node’s child list:

// create a new XML document

var doc:XML = new XML();

// create a root node

var rootNode:XMLNode = doc.createElement("rootNode");

// create three child nodes

var oldest:XMLNode = doc.createElement("oldest");

var middle:XMLNode = doc.createElement("middle");

var youngest:XMLNode = doc.createElement("youngest");

// add the rootNode as the root of the XML document tree

doc.appendChild(rootNode);

// add each of the child nodes as children of rootNode

rootNode.appendChild(oldest);

rootNode.appendChild(middle);

rootNode.appendChild(youngest);

// use lastChild to iterate through the child nodes of rootNode

for (var aNode:XMLNode = rootNode.lastChild; aNode != null; aNode =

aNode.previousSibling) {

trace(aNode);

}
