Greetings,
It's not clear from your post what you are looking for.
But
NSTOC, if used like this:
{{nstoc :}}
will dump an unordered list of your entire root namespace; expanded, and unbulleted.
You could style it differently if the results don't quite look the way you wish.
You might also want to look at the
http://www.dokuwiki.org/plugin:nspages plugin.
