[Orgmode] Need help exporting subtrees to html

[Juan Reyero]

Greetings,

I have written a function to export org-mode subtrees as jekyll posts,
http://juanreyero.com/open/org-jekyll/  The idea is that any entry in
an org-publish project that has a :blog: keyword and an :on: property
with a timestamp should be exported to a _posts directory with the
year-month-day-title.html that jekyll expects, with the properties as
front-matter.

I was very happy with it, until I realized that the levels of the
headers in the exported file (h2, h3, etc) depend on the indentation
of the subtree in the outline.  I wanted to be able to add a :blog:
subtree anywhere in my project's files, and get it always exported the
same, regardless of where in the outline it is.

Is there any reasonably simple way to overcome this problem?  I am using:

(org-narrow-to-subtree)
(setq html (org-export-as-html nil nil nil 'string t nil))

to do the exporting (all the code is in github,
http://github.com/juanre/org-jekyll).  In summary, what I need is an
org-export-as-html that treats the least indented outline as a
0-indentation.

Best,

Juan
