event-based XML parsing
Wed Nov 22 11:05:53 CET 2000
Down to more earthly matters, I've published a new version of
xmerl, with an example of an event-based interface to the
XML processor. It seems to work quite well for very large files.
The example event-based parser is 122 lines of Erlang code
(not counting the actual processor, which is 1971 LOC).
The trick to parsing large XML files without using up lots of memory
is an accumulator hook function which accumulates nothing:
AccF = fun(X, Acc, S) ->
All the data is instead handled in a user-provided event hook
The README.html file has much more documentation.
