I’m creating a XML-powered photo gallery with categories and I’m having some problems loading all this information into flash. I created the following classes:

```auto

class Category
{
	public var id:Number;
	public var categoryTitle:String;
	public var photos:Array;

	public function Category(i:Number, t:String)
	{
		id = i;
		categoryTitle = t;
		photos = new Array();
	}
	
	public function addPhoto(p:Photo)
	{
		photos.push(p);
	}
}

```

```auto

class Photo
{	
	public var full:String;
	public var thumbnail:String;

	public function Photo(f:String, t:String)
	{
		full = f;
		thumbnail = t;
	}	
}

```

My XML files look like this:

**categories.xml**

```auto

<categories>
	<category categoryTitle="People" id="0" />
	<category categoryTitle="Nature" id="1" />
	<category categoryTitle="Buildings" id="2" />
</categories>

```

**category1.xml** (number varies)

```auto

<photos>
	<photo full="photos/tree.jpg" thumbnail="photos/th_tree.jpg" />
	<photo full="photos/rabbit.jpg" thumbnail="photos/th_rabbit.jpg" />
	<photo full="photos/water.jpg" thumbnail="photos/th_water.jpg" />
	<photo full="photos/sun.jpg" thumbnail="photos/th_sun.jpg" />
</photos >

```

I tried creating an array called _categories_ with all the categories which contain all the photos but I haven’t been able to get it to work properly. Everytime the code was run before the XML was loaded… and when using onLoad I had to nest a couple of them which became a big mess. I’ve also tried going fully Object Oriented using Createage’s XMLLoader ([http://www.createage.com/blog/?p=104](http://www.createage.com/blog/?p=104)).

**Any ideas on how to achieve this?**
