You can use noweb reference syntax.

#+name: collect-headings
#+begin_src emacs-lisp :results silent
;; Collect all the headings in current buffer.
(concat
 "* Top\n"
 (mapconcat
  #'identity
  (org-map-entries
   '(concat "*"
            (buffer-substring-no-properties
             (line-beginning-position) (line-end-position))))
  "\n"))
#+end_src

#+begin_src plantuml :noweb yes :file my-diagram.png
@startwbs
<<collect-headings()>>
@endwbs
#+end_src
