Load XMl file in ActionScripting 3.0
First create the xml file and save as menu.xml
<site>
<links>
<link><![CDATA[home.html]]></link>
<title><![CDATA[HOME]]></title>
<image><![CDATA[images/1.png]]></image>
<des><![CDATA[car 1]]></des>
</links>
<links>
<link><![CDATA[about.html]]></link>
<title><![CDATA[ABOUT]]></title>
<image><![CDATA[images/2.png]]></image>
<des><![CDATA[car 2]]></des>
</links>
</links>
</site>
Note that the <![CDATA[car 2]]> code is just telling flash to treat it as expression or code.
In Flash enter the following lines:
var myXml:XML;
var myLoader:URLLoader = new URLLoader();
myLoader.load(new URLRequest("menu.xml"));
myLoader.addEventListener(Event.COMPLETE, runData);
function runData(e:Event):void{
myXml = new XML(myLoader.data);
myXml.ignoreWhitespace = true;
trace(myXml);
}
Let's go over the flash actionscript that you just entered.
The first two lines create an XML variable called myXML, and a URLLoader called myLoader.
var myXml:XML;
var myLoader:URLLoader = new URLLoader();
Next, we load the menu.xml into myLoader with the following code:
myLoader.load(new URLRequest("menu.xml"));
Next line, we add an event listener to run the runData function once the xml is completely loaded:
myLoader.addEventListener(Event.COMPLETE, runData);
The last bit is the runData function, we declare the function and pass in e as an event with no return value (as denoted in void):
function runData(e:Event):void{
our function here
}
We pass in the myLoader.data to myXml, set ignoreWhitespace to true and trace out myXml:
function runData(e:Event):void{
myXml = new XML(myLoader.data);
myXml.ignoreWhitespace = true;
trace(myXml);
}
Now that you have loaded the XML, let's access these values. We can access these listing with several operators. First is (.), the (@), and the square([]). The dot (.) enables you access elements of your XML, the (@) lets you access attributes of an element, and the square ([]) allows you to access a property by name or index.
trace(myXml.links[0].link); //Display: home.html
trace(myXml.links.(link.text() == "about.html").title); //Display: ABOUT
This is just a basic to Flash ActionScripting 3.0. I'm sure you will be able to find out more from the web.
