Simple XML subtitle/dialog?

Hi,

Does anyone know if there's a simple dialog example that just loads text lines from a file?

All I need is to have a way to display subtitles, as my game has lot of voice acting in it. I would need to be able to send my easily editable dialog text to translators.

I tried searching but all related posts felt outdated.

I'm able to load text file using ajax, but does anyone have any ideas how I could choose what row to load instead of the whole text file?
