I'm low level as3 programmer and I need help whit this code:

I have gallery XML file:

 <gallery>
    <item>
        <id>1</id>
        <strana>0</strana>
        <naslov>Lokacije</naslov>
        <aktuelno>1</aktuelno>
        <slika>1.jpg</slika>
    </item>
    <item>
        <id>2</id>
        <strana>2</strana>
        <naslov>Coaching</naslov>
        <aktuelno>1</aktuelno>
        <slika>2.jpg</slika>
    </item>
    <item>
        <id>3</id>
        <strana>0</strana>
        <naslov><![CDATA[O.Å . Bratstvo - panel]]></naslov>
        <aktuelno>0</aktuelno>
        <slika>3.jpg</slika>
    </item>  
</gallery>

And:

var loader: URLLoader = new URLLoader(); loader.load(new URLRequest("gallery.xml");

var xml = new XML(evt.target.data);
for each(var item in xml..item) {
    centralniText.htmlText = item.slika;
}

After storing your loaded xml data in an XML object:

var xml:XML = XML(URLLoader(event.target).data);

All you have to do is return an xml list value from the previous XML object's children() method:

var xmlList:XMLList = xml.children();

Then you can set it as your TextField object's htmlText property's value:

centralniText.htmlText = xmlList;

[UPDATE]

To access a specific element you can do the following:

trace(xmlList.slika[0]); // outputs: 1.jpg
trace(xmlList.slika[1]); // outputs: 2.jpg
trace(xmlList.slika[2]); // outputs: 3.jpg

In your for each loop, you always assign the current item’s value to the text field, overwriting previous values. So you need to append the text, for example like this:

var text:String = '';
for each(var item in xml..item) {
    text += item.slika;
}
centralniText.htmlText = text;
