See

http://www.erlang.se/doc/doc-5.4/lib/kernel-2.10/doc/html/code.html

(hint: take a look at replace_path/2)

xmerl isn't loaded by the normal Erlang startup, so you don't need to
worry about purging the old code first, though it's well worth
learning how that works too. It's one of the especially neat and
unusual things about Erlang.
