You mean you want to insert it as raw HTML, or just directly draw what
you've already filtered out?  The display engine relies on certain pieces
of the parse tree being there at the beginning.  Most notably the special
'*document' tag make sit set up the local drawing variables and create a
special buffer.  You could do something like:

(defun nnultimate-draw-content (content)
  (w3-draw-tree (list (list '*document nil content)))
  (w3-finish-drawing))
