This returns the link at the line, it assumes one link per line:

#+BEGIN_SRC emacs-lisp
  (defun test ()
    (save-excursion
      (move-beginning-of-line 1)
      (if (search-forward-regexp org-any-link-re 
      (line-end-position) t)
          (let* ((complete-link (match-string 0))
                 (last-place (string-match "\\]" complete-link)))
            (substring-no-properties complete-link 2 
            last-place))))
 
#+END_SRC

Best,
