Can I use babel to generate html to be exported in a #+BEGIN_HTML
... section using `org-export-region-as-html'? I ask because the
behaviour I am seeing is different depending on whether I use that
function or `org-export-as-html'. The former function exports
the html code to show the html code, whereas the later exports
the html code directly as html.
To concretize that a bit, I have a pair of functions that look
like this (have I misunderstood they way the export is supposed
to work?) --
(defun embed-pdf-function (pdf-file)
(concat "<iframe src=\"http://docs.google.com/gview?url=http://example.net/"
pdf-file
"&embedded=true\" style=\"width:25em; height:38em;\"
frameborder=\"0\"></iframe>\n"))
(defun embed-pdf (pdf-file)
(interactive "MFile name: ")
(insert (concat
"#+BEGIN_SRC emacs-lisp :exports results :results html\n"
"(embed-pdf-function \"" pdf-file "\")\n"
"#+END_SRC")))
When I call the first in an org buffer and give it "foo.pdf" as
an argument, it inserts something that looks like this:
#+BEGIN_SRC emacs-lisp :exports results :results html
(embed-pdf-function "foo.pdf")
#+END_SRC
When I use `org-export-as-html' in that buffer I end up with an
html file that includes this, which IS what I would want:
<iframe src="http://docs.google.com/gview?url=http://example.net/foo.pdf&embedded=true"
style="width:25em; height:38em;" frameborder="0"></iframe>
But, when I instead use `org-export-region-as-html' in a
program (because I am hoping to get the results as a string,
rather than in a buffer) using something like this --
(org-export-region-as-html (point-min) (point-max) t 'string)
-- the result I get in the html looks like this:
<pre class="example">
<iframe src="http://docs.google.com/gview?url=http://example.net/foo.pdf&embedded=true"
style="width:25em; height:38em;" frameborder="0"></iframe>
</pre>
Which of course is not the iframe I was hoping for, but is the
code to render the code for it in html.
Should the region export function work the way I am hoping at
all? -- can it be made to do so?
(
I also have the following set globally, if it is relevant:
(setq org-confirm-babel-evaluate nil)
(setq org-export-babel-evaluate t)
and --
M-x org-version RET ==> "Org-mode version 7.8.11"
)

Actually I think I have a simpler version of this question now.
I have this function:
(defun render-one (file)
(with-temp-buffer
(insert-file file)
(org-export-as-html nil nil nil 'string t)))
With the last line being the important bit.
If I open a file, foo.org, that has the #+BEING_SRC bit that I
want to export, and put this line in the buffer and evaluate it:
(org-export-as-html nil nil nil 'string t)
then the result I get is correct -- the html that I want is
embedded in the resulting string. But if instead I evaluate
(render-one "~/foo.org")
using the function above which should (I assume) do the same
thing, it does not work. Instead, the html code I want is
wrapped in <pre> tags and angle brackets changed to html
entities.
So, it seems that something about running the export function in
my code above makes it ignore my :results html setting in the
code block. Is this a security thing? Is there a variable that
I need to let-bind in my function or something?
Thanks for any help.

Try
(defun render-one (file)
(with-temp-buffer
(insert-file file)
(org-mode)
(org-export-as-html nil nil nil 'string t)))
(org-mode) is important here.

Well, I still don't know why it behaves the way I've described, but it
works the way I want if instead of the above function, I use:
(defun render-one (file)
(save-excursion
(let ((buffer (set-buffer (find-file file))))
(setq rtn (org-export-as-html nil nil nil 'string t))
(kill-buffer buffer)
rtn)))
-- using find-file and messing with the buffer stuff by hand, instead
of using `with-temp-buffer' and `insert-file', which later strikes me
as neater, and possibly faster (I am using it in batch to process
multiple files) but the other way works, so that's fine. Thanks.

Just out of curiosity, did it work for you the way I suggested?
find-file will load the appropriate mode, hence no need for (org-mode)
in your latest function.

In case anyone might be interested in this, here is what I think is a
minimal example. As I said, I am fine with it for my purposes, but
since the behaviour seems inconsistent (from my possibly limited
perspective) I thought I ought to at least specify as clearly as
possible what is going on:
First, with emacs -Q, and with a file called ~/tmp/foo.org
It's contents are only this:
#+BEGIN_SRC emacs-lisp :exports results :results html
"<>"
#+END_SRC
Now, slightly reformatted for clarity, M-x ielm --
*** Welcome to IELM *** Type (describe-mode) for help.
ELISP> (defun render-with-find-file (file)
(save-excursion
(let ((buffer (set-buffer (find-file file))))
(setq rtn (org-export-as-html nil nil nil 'string t))

rtn)))
==> render-with-find-file
ELISP> (defun render-with-temp-buffer (file)
(with-temp-buffer

(org-mode) ; doesn't actually seem to have any effect
