firstChild (XMLNode.firstChild property)
public firstChild : XMLNode [read-only]
Evaluates the specified XML object and references the first child in the parent node's child
list. This property is null if the node does not have children. This property is undefined if
the node is a text node. This is a read-only property and cannot be used to manipulate child
nodes; use the appendChild(), insertBefore(), and removeNode() methods to
manipulate child nodes.

Example
The following example shows how to use XML.firstChild to loop through a node's child
nodes:
// 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 firstChild to iterate through the child nodes of rootNode
for (var aNode:XMLNode = rootNode.firstChild; aNode != null; aNode =
aNode.nextSibling) {
trace(aNode);
}
// output:
//
//
