==Adding Attributes to an XML Element==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){

var example:XML = <example><someElement/></example>;

example.someElement.@number = 12.1;
example.someElement.@string = "example";
example.someElement.@boolean = true;
example.someElement.@array = ["a", null, 7, undefined, "c"];

trace( example );

example.someElement.@["bad-variable-name"] = "yes";

example.someElement.@["color" + num] = "red";
}
}
}
</source>

==Create the XML structure with a string==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var str:String = "<gamescore><username>username </username>"
+ "<score>111</score></gamescore>";

// Pass the string to the constructor to create an XML object
var example:XML = new XML( str );
}
}
}
</source>

==Creating an XML Object==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var example:XML = <abc><a>eh</a><b>bee</b><c>see</c></abc>;
var username:String = "Darron";
var score:int = 1000;

var example:XML = <gamescore>
<username>{username}</username>
<score>{score}</score>
</gamescore>;
}
}
}
</source>

==Finding Elements by Name==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var fruit:XML = <fruit><name>Apple</name></fruit>;

trace( fruit.name );

var author:XML = <author><name><firstName>Darron</firstName></name></author>;

trace( author.name.firstName );
}
}
}
</source>

==Reading Elements in an XML Tree==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){

var menu:XML = <menu>
<menuitem label="File">
<menuitem label="New"/>
</menuitem>
<menuitem label="Help">
<menuitem label="About"/>
</menuitem>
This is a text node
</menu>;

for each ( var element:XML in menu.elements( ) ) {
trace( element.@label );
}
var menu:XML = <menu>
<menuitem label="File">
<menuitem label="New"/>
</menuitem>
<menuitem label="Help">
<menuitem label="About"/>
</menuitem>
This is a text node
</menu>;

walk( menu );

function walk( node:XML ):void {
for each ( var element:XML in node.elements( ) ) {
trace( element.@label );
walk( element );
}
}
}
}
}
</source>

==Reading Text Nodes and Their Values==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var book:XML = <book>
<title>ActionScript</title>
</book>;

var title:String = book.title.toString( );

trace( title );
}
}
}
</source>

==Understanding the XML Classes==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var myXML:XML = <message>Hello, world!</message>;
// An XMLList is a numbered set of XML objects.
var list:XML = <list>
<item id="58" />
<item id="135" />
<item id="12" />
</list>;
var items:XMLList = list.item;
trace(items);
trace(items.length());
trace(items[1].toXMLString());
}
}
}
</source>

==Using Expressions within Literals: embed ActionScript code directly into your XML data.==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var squareLength:Number = 10;
var circleRadius:Number = 5;
var shapeData:XML = <shapeList>
<shape type="square" size={squareLength} />
<shape type="cicle" size={circleRadius} />
</shapeList>;
trace(shapeData.toXMLString());
}
}
}
</source>
