if your text is already a string, then you can use split-string to
turn it into a list, by using “\n” as separator.
You can turn a block of text into a string by using buffer-substring-
no-properties.
alternatively, the following i wrote in my early lisp day that does
what you want. I still use it.
(defun grab-lines (n)
"Delete the next n lines and return a list
where each element is a line."
(interactive)
(move-beginning-of-line 1)
(let (t1 t2 cl (lines '()))
(dotimes (x n)
(progn
(setq t1 (point))
(move-end-of-line nil)
(setq t2 (point))
(setq cl (buffer-substring-no-properties t1 t2))
(delete-region t1 t2)
(delete-char 1)
(push cl lines)
)
)
(setq lines (reverse lines))
; (prin1 lines (current-buffer))
))
