How to migrate AS2 to AS3.?

Question

How to convert ActionScript 2.0 code to ActionScript 3.0

this is code :

    //***********************************************************
    var theXML:XML = new XML();
    theXML.ignoreWhite = true;
    theXML.onLoad = function() {
    var nodes = this.firstChild.childNodes;
    for (i=0;i<nodes.length;i++){
    theList.addItem(nodes[i].firstChild.nodeValue,i);
    }
    }

    theXML.load("http://localhost/conn.php");
    //***********************************************************

This is my PHP code that echo's an XML string :

echo "<?xml version=\"1.0\"?>\n"; 
echo "<name>\n"; 

while ( $line = mysql_fetch_assoc($res) ) 
{ echo "<item>" . $line["name"] . "</item>\n"; } 

echo "</name>\n"

Using AS3, how do I parse the XML string as actual XML data with nodes?

Answer 1

There are many examples of how to work with XML in AS3, and how to migrate AS2 to AS3.

This would be the equivalent of what you posted:

var loader:URLLoader = new URLLoader();
loader.load(new URLRequest("http://localhost/conn.php"));
loader.addEventListener(Event.COMPLETE, loaderComplete);

function loaderComplete(e:Event):void {
    XML.ignoreWhitespace = true;
    var xml:XML = new XML(loader.data);
    var nodes:XMLList = xml.child(0).children();
    for (var i:int = 0; i < nodes.length(); i++) {
        theList.addItem(nodes[i].child(0).text());
    }
}

Note that in AS3 you can reference XML nodes by name, for example xml.gallery.image[3].url instead of xml.child(0).children()[3].child(0), etc.
