Hi,
a slight enhancement:
#+begin_src emacs-lisp
(defun tj/src-block-interpreter (src-block contents)
"Interpret SRC-BLOCK element as Org syntax. CONTENTS is nil."
(let ((lang (org-element-property :language src-block))
(switches (org-element-property :switches src-block))
(params (org-element-property :parameters src-block))
(headers (org-element-property :header src-block))
(value
(let ((val (org-element-property :value src-block)))
(cond
((or org-src-preserve-indentation
(org-element-property :preserve-indent src-block))
val)
((zerop org-edit-src-content-indentation) val)
(t
(let ((ind (make-string
org-edit-src-content-indentation ?\s)))
(replace-regexp-in-string
"\\(^\\)[ \t]*\\S-" ind val nil nil 1))))))
packed-headers)
(concat (format "%s#+BEGIN_SRC%s\n"
(progn
(while headers
(setq packed-headers
(concat
(format "#+HEADER: %s\n"
(pop headers))
packed-headers)))
(or packed-headers ""))
(concat (and lang (concat " " lang))
(and switches (concat " " switches))
(and params (concat " " params))))
(org-escape-code-in-string value)
;; (save-match-data
;; (if (looking-at "^$") "" "\n"))
"#+END_SRC")))
#+end_src
#+results:
: tj/src-block-interpreter
Parse this src-block (with point at beg of block):
,----
| M-: (setq ptree (org-element-at-point))
`----
#+header: :results raw
#+begin_src emacs-lisp
(message "hello world")
#+end_src
#+results:
hello world
Then evaluate
#+begin_src emacs-lisp
(org-element-src-block-interpreter ptree nil)
#+end_src
#+results:
: #+BEGIN_SRC emacs-lisp
: (message "hello world")
: #+END_SRC
#+begin_src emacs-lisp
(tj/src-block-interpreter ptree nil)
#+end_src
#+results:
: #+HEADER: :results raw
: #+BEGIN_SRC emacs-lisp
: (message "hello world")
: #+END_SRC

cheers,
Thorsten
