[erlang-questions] xmerl still slow?

I think that the thing that is slow in xmerl
is the actual parsing.

xmerl:export_simple/2 has nothing to do with that.
It assumes that the user provides a simplified 
representation of XML - {Tag, [Attr], Content},
where Attr = {Key, ValueStr}.

(It can also take regular xmerl records, though...) 

If you have a simple enough XML structure to begin
with, and you really don't need things like verifying
parse, XPATH, entity expansion, Unicode, etc., you can 
easily put together a customized XML parser.

See e.g.
