How do I format different lines of text differently, from a textfield created in AS3, with text populated from a txt file? - actionscript-3

Question

So I have a flash file in AS3, latest version of flash.
It creates a text box in AS3. It then uses AS3 to grab text from a text file (2 lines) and loads it in. I then used further code to format the text size, font, color etc.
But NOW...I need line 1 of the text box to be a certain format (large, caps) and the second line to be a different format (smaller, no caps)
Here is all my code below:
//BEGIN TXT LOADER
var myTextLoader:URLLoader = new URLLoader();
var winnerText:TextField = new TextField();
myTextLoader.addEventListener(Event.COMPLETE, onLoaded);
function onLoaded(e:Event):void {
winnerText.text = e.target.data;
addChild(winnerText);
}
myTextLoader.load(new URLRequest("EditableText.txt"));
//BEGIN TEXT BOX FORMATTING
winnerText.width = 1920;
winnerText.height = 300;
winnerText.y = 430;
//BEGIN TEXT & FONT FORMATTING
var casinoBranding:TextFormat = new TextFormat();
casinoBranding.size = 90;
casinoBranding.align = TextFormatAlign.CENTER;
casinoBranding.font = "Bliss Pro";
casinoBranding.leading = -50;
winnerText.defaultTextFormat = casinoBranding;

Answer 1

You can apply a TextFormat like #Aaron suggests. Another way of doing is to use stylesheets. Here is an example

Answer 2

You can apply a TextFormat to a specific range of text using TextField/setTextFormat().
To apply a different text format to the first line of text you can do this:
var casinoBranding:TextFormat = new TextFormat();
var casinoBrandingFirstLine:TextFormat = new TextFormat();
// ... apply formatting options
function onLoaded(e:Event):void {
winnerText.defaultTextFormat = casinoBranding;
winnerText.text = e.target.data;
winnerText.setTextFormat(casinoBrandingFirstLine, 0, winnerText.getLineOffset(1));
}
Note that if word wrapping is involved it changes what the "first line" really means.
