   Which is not always a bad choice for dealing with xml. It has served me
well. Of course xml is pretty hard to deal with in Perl without passing it
through a parser first, which puts you right back in the same situation in
terms of the references. 

   But if you're using Perl you might as well follow in the long tradition
of Perl hacks that _work right now_ (as opposed to tomorrow,
when something changes). Substitute some string that won't
bother the xml parser but is also sure not to naturally occur in your
document for each entity reference. Grab the Perl xml parser and parse
your file. Substitute the original references back
in. Then spit out your transformed file. This is ugly for a couple of
reasons, mainly that it relies on implementation details of the Perl xml
module (built on expat I think). But I think it might be the easiest
way to get what you're asking for. There is also the question: What's
wrong with the Unicode equivalents that you get from the xml parser?
