Is there any way to open a file whose name is written in another file? For example, I want to open file A in emacs. The path and name of file A is recorded in file B. The filename of file B is fixed, but file A is changeable. So I hope emacs can read the path&name of file A in file B first, and open file A.

Try this:
(progn
(find-file "b.txt")
(goto-char 0)
(find-file (thing-at-point 'filename)) )
If you want to do something similar interactively, try
this:
(defun find-file-at-line (&optional other-window)
(interactive "P")
(let ((possible-filename (thing-at-point 'filename))
(find-f (if other-window 'find-file-other-window 'find-file)) )
(if (and possible-filename (file-exists-p possible-filename))
(apply find-f (list possible-filename))
(progn
(forward-char 1)
(find-file-at-line) ))))

`find-file-at-point' works if point is exactly at the
path (hence the name), and you have to confirm the
path in the metabuffer with RET.
