XML or another way?

So I have extended my textfield so I can add a some text, a style, an x and y position.

var clientText:MyTextField = new MyTextField(“Client:”, “style1”, 75, 60);
addChild(clientText);

The problem is the text is starting to get a bit long and I need a way to insert large amount of text neatly. I don’t really want to use xml I would prefer to just have it in the ide like in the attached image. However formatting it in this way gives me the error

1095: Syntax error: A string literal must be terminated before the line break.
