Hi all.
I am new at flash action script and i have been trying to write a code for an island guide. I have all my data in an XML and I am trying to parse them in flash. Everything is ok with the texts but i have a problem with an arry variable that i have for the filepath of the photos that will be used for each island...
I found a "photo holder" script from "flashmo" and i modded it for my case and I am trying to determine the length of the array so that it only brings up as many "photo holders" as the picture paths given in the XML. But i can't seem to distiguish between the filled "ISLAND_PHOTO" atributes of the XML and the empty ones... I have tried "!=null", "!=undefined", even deliberately puting in some text to dermine the empty ones like "empty" and then trying a "!="emtpy"" or any other text or number but still i can not seperate them...
here is the XML "about.xml":
Code:
<?xml version="1.0" encoding="utf8"?>

and the part of the script that i have a problem with:
Code:
var xml_file:String = "about.xml";
var folder:String = "thumbnails/";
var MY_PIC:Array = new Array();
var total:Number;
var i:Number;
var xml:XML = new XML();
xml.onLoad = function() {
item_list.fm_item._visible = false;
var nodes = this.firstChild.firstChild.lastChild.childNodes;
total = nodes.length;
for (i=0; i<total; i++) {
if (nodes[i] != null);
{
MY_PIC[i] = nodes[i].childNodes;
}
}
create_item_list();
};
xml.load(xml_file);
xml.ignoreWhite = true;
function create_item_list():Void {
for (i=0; i<MY_PIC.length; i++) {
var item = flashmo_item.duplicateMovieClip("fm_item"+i, i);
item.fm_pic.loadMovie(folder+MY_PIC[i]);
item._x = i*320;
}
The script should just dublicate a "photo holder" (actually called "fm_item" in the script) function for as many times as the MY_PIC.length... but that is allways 10.. as many as I have reserved in the XML... The script reads them all as not null... It works fine for the 3 paths that are defined and gives me an output of :
Code:
Error opening URL 'file:///C|/Users/user/Desktop/thumbnails/'
for the "ISLAND_PHOTO" atributes that don't have a path in them.
Any help would be greatly apricated... I have been looking at that script and trying out different solutions for a few days now, and i am not any closer to making it work the way i want it to...
