// 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);

}

// output:

// <youngest />

// <middle />

// <oldest />

The following example creates a new XML packet and uses the XML.lastChild property to

iterate through the child nodes of the root node:

// create a new XML document

var doc:XML = new XML("");

var rootNode:XMLNode = doc.firstChild;
