Answer 1

You could just litterally break line it yourself :
<data>
Sample
Text ABC
</data>

If your new line is still not showing up, just remember that how an app interprets/read texts, including newlines, is up to it. The application sometimes may automatically run together text separated by newlines.
This is very common in HTML browser , to fix that, you could either use <br> in HTML or use a wrap block to an element such as 'div' , which should cause a line break after the enclosed text. You can also try using CSS's white-space
