Section numbering using xmerl:export

[Vlad Dumitrescu]

Hi,

I don't know about the xmerl details, but I think it might be risky to rely
on a implementation dependent feature... Of course, this depends on your
application's use.

The safe way would be going through the tree and numbering the nodes along
the path. I have written a small routine that will traverse a xml tree and
call a fun with every node. I think it might help you too (or others).

best regards,
Vlad

traverse(List, Fun) when list(List) ->

traverse(E, _Fun) ->
    E.
