Stacking Dynamic Text Fields Flash/ActionScript 3

Question

I am adding a series of text fields through a loop based on an XML file. The width of the fields is always going to be 200 px so depending on how much text is contained in the XML node, the height of the text field will vary. I need a way to stack these fields on top of each other based on their height plus say a 10 px space between each. Below is how I am creating the text fields.

for(var i:int; i < xml.item.length(); i++)
{
    var theText:TextField = new TextField();
    addChild(theText);
    theText.wordWrap = true;
    theText.width = 200;
    theText.antiAliasType = AntiAliasType.ADVANCED;
    theText.autoSize = TextFieldAutoSize.LEFT;
    theText.selectable = false;
    theText.htmlText = xml.item[i].@theText;
};

You can keep track of the height by using the height of the text field.

var startHeight:int = 0;
for(var i:int; i < xml.item.length(); i++)
{
    var theText:TextField = new TextField();
    addChild(theText);

    theText.y = startHeight;

    theText.wordWrap = true;
    theText.width = 200;
    theText.antiAliasType = AntiAliasType.ADVANCED;
    theText.autoSize = TextFieldAutoSize.LEFT;
    theText.selectable = false;
    theText.htmlText = xml.item[i].@theText;

    startHeight += theText.height + 10;
}

Thanks! I knew it was something simple. Only one small change for anyone else who comes across this, the first line should be: "var startHeight:int = 0;"

Haha yeah editing that too much C++/AS3 mixing does that sometimes :)
