Exporting subtitles

Hello,
I am using Davinci 14.
I have created a track with some text clip for subtitles.
I was wondering if I could export this track as a text file for subtitles.
I now I can export a fcpxml but from then I don't know how to make a conformed subtitles text file.
Or do I have to create it by end ?
Thanks a lot.
Alexandre

Version 15 has a subtitle feature with export, 14 didn't have that yet.

Thank you!
