Hello,
I used to generate html code with a python script using org-babel, like this:
%-------
example.org ---------%
* This is an example of export in HTML
#+BEGIN_SRC python :exports results :results output :wrap HTML
print "<ul> <li> first item</li>"
print "<li> second item </li>"
print "</ul>"
#+END_SRC
%-------
example.org ---------%
This used to work just fine and produce a nice unordered list in html. Until the moment I updated to the current development version:
Org-mode version 8.3.4 (release_8.3.4-588-g924431 @ /home/lipari/elisp/org-mode/lisp/)
