XML in ActionScript

programming flash
1

Hi all,

I am creating a crawler in actionscript and i am taking an object oriented approach, which means that i have a class which is saved as an .as file. I then call the class in a .fla file.

The problem i am facing is that i am trying to read from an external xml file in the init function and populate an array with the contents of the xml file. I then try to print the length of the array but it prints undefined.

Actually i create a function that loads the xml file and returns an xml file. I then call that function in the init function. What i did was to create an xml object and assign it to the function like so: xmlfil = view(“filename”); but it gives me undefined when i run. Please help me out.

ActionScript class

dynamic class Crawler
{

public var filename:String;

function Crawler(filename:String)
{
this.filename = filename;

}

function init()
{

var xmlfil:XML = new XML("filename");

xmlfil = view("filename");

createTextField("scroller_txt", 1, -500,100, 2000, 50);

scroller_txt.html = true;
scroller_txt.background = true;
scroller_txt.backgroundColor = 0xFDF5E6;
scroller_txt._y = 300;
trace(scroller_txt.backgroundColor);
           
            
          
    var myArray:Array = xmlfil.firstChild.childNodes;
    trace(xmlfil);
    trace("the length of the array is"+ myArray.length);

for(var i=0; i<myArray.length;i++)
{ 

            
    if(i%2 == 1)
{
   
    
    var sped = 10;

scroller_txt.htmlText =" “+”<img src=“E:\HELENA E stuff\Helena’s Game 10-23-2006\flash\ igo.jpg”>" + myArray[1].firstChild.nodeValue;

for( m=0; m<50; m++)
{

if(m%2 == 1)
{

scroller_txt.htmlText+= “<img src=“E:\HELENA E stuff\Helena’s Game 10-23-2006\flash\ igo.jpg”>”+ myArray[m+2].firstChild.nodeValue;

}

}
scroller_txt.spacebuffer = " ";
scroller_txt.border = true;
scroller_txt.speed = sped;

myTextFormat = new TextFormat();
myTextFormat.font = “Verdana”; //this should be a string
myTextFormat.color = black;
myTextFormat.size = 13;

scroller_txt.setTextFormat(myTextFormat);
scroller_txt.spaceSize = 50;//scroller_txt.getNewTextFormat().getTextExtent(" ").width;
scroller_txt.spacesRequired = Math.ceil(scroller_txt._width/scroller_txt.spaceSize);
for (var p = 0; p<scroller_txt.spacesRequired; p++) {
scroller_txt.spacebuffer += " ";

}

scroller_txt.htmlText = scroller_txt.spacebuffer+scroller_txt.htmlText+scroller_txt.spacebuffer;
scroller_txt.hscrollInterval = function() {
if (this.hscroll == this.maxhscroll) {

this.hscroll = 0;
}
this.hscroll += 1;
};
setInterval(scroller_txt, “hscrollInterval”, 50);

}
}

}

function you (filename)
{

var i:String = filename;

}

public function view (filename):XML {

var xmlFile:XML = new XML(filename);

    xmlFile.load(filename);
    
    
    
    xmlFile.onLoad = function(bSuccess:Boolean):Void{

if (bSuccess){
trace(“loading successful”);

}
else {
trace(“Doc failed to load or parse”);
}

};

xmlFile.onLoad = init;
xmlFile.load(filename);
trace(“the init”+ xmlFile);
return xmlFile;

}

//}
}

[U].fla file

[/U]var filename:String = “E:\HELENA E stuff\Helena’s Game 10-23-2006\flash\datta.xml”;
var craw:Crawler = new Crawler(filename);
craw.view(filename);
