Private/public problem

1

Hi.
Everything I need is find some nodeValue in xml file like this:


<school name="13">
  <place name="facade">1.jpg</place>
  <place name="entrance">2.jpg</place>
<school>

I wrote an abstract xml class which loads file:


class ruhe.util.AbstractXML extends XML 
{
    
    private var link:String;
    private var event:String = "onXMLLoad";
    private var errorEvent:String = "onXMLLoadError";
    
    var dispatchEvent:Function;
    var addEventListener:Function;


    public function AbstractXML(xml_url : String)
    {
        super();
        EventDispatcher.initialize(this);
        ignoreWhite = true;
        link = xml_url;
        this.load(link);
    }
    
    private function onLoad(success:Boolean):Void
    {
        if(success)
        {
            this.dispatchEvent({type: event});
        }
        else
        {
            this.dispatchEvent({type: errorEvent});    
        }
    }

}

and xml handler class:


class ruhe.school.XmlHandler {

    private var info : AbstractXML;
    private var hash : Object;

    public function XmlHandler() 
    {
        info = new AbstractXML("tree.xml");

        info.addEventListener("onXMLLoad", Proxy.create(this, processXML));
        info.addEventListener("onXMLLoadError", Proxy.create(this, raiseError));
    }

    private function raiseError() : Void
    {
        throw new Error("no xml found");
    }

    private function processXML() : Void{}

    public function find(lookFor : String) : String
    {
        for (var n : Number = 0; n < info.firstChild.childNodes.length; n++)
        {
            if(info.firstChild.childNodes[n].attributes.name == lookFor)
            {
                return info.firstChild.childNodes[n].firstChild.nodeValue;
            }
        }
    }
}

**find **method doesn’t work. it returns undefined. But when I change it to private and call from the **processXML **method everything works well.


private function processXML() : Void
{
    trace (this.find("entrance")); *==> 2.jpg*
}

private function find(lookFor : String) : String
{
    for (var n : Number = 0; n < info.firstChild.childNodes.length; n++)
    {
        if(info.firstChild.childNodes[n].attributes.name == lookFor)
        {
            return info.firstChild.childNodes[n].firstChild.nodeValue;
        }
     }
 }

I thinck there is a stupid mistake somewhere in my code. I need public function find, not private.
