How do I add line breaks to text fields?

I have a string (from xml) I want to display on stage. Currently I have a text field that I am simply assigning the text to (no problems) but I want to add line breaks at certain points.after reading this line:

“If the text includes a line break (for example, "
" or “\r”), the bottom is also resized to fit the next line of text.”

found here:

I got the impression that I could add a string to text with a line break in it? If I try and add it to my xml file it simply writes it out as normal characters.

I am fairly sure I can do it by showing as HTML but was wondering if there was another way ?

Thanks for any help!
