I guess you write a function that uses the following Vim functions to
extract your text and append it to a register:

:h getline()
:h line()
:h foldclose()
:h foldtextexpr()
:h setreg()

And then have mapping such as:

:nmap ,y :g/\n/call MyYank()<CR>

.. to scan the entire buffer so that when you return from MyYank() your
outline would be available in one of the A-Z registers.

I believe you'd need to keep track of whether the current line is the
top line of the fold, or you'd end up with the entire fold appended to
the register.. not what you want obviously.

There are probably less kludgy ways to do that, but that's what comes to
mind..
