Can anyone point me to a good tutorial/sage advice on compressing XML RSS pages? While a lot of the bloggers we host have switched over to (or started with) WordPress and it's PHP-based RSS feeds (which compress quite nicely with mod_gzip and ob_gzhandler, by the way), some are sticking with Movable Type and it's .xml feeds, which we haven't figured out a way to compress yet, knowing nothing about XML.
Some quick monkeying around parsing the XML as PHP and compressing it didn't work at all well... any of the three or four ways we tried it.
It's not a huge problem, yet... but it'd be nice to have a solution in place *before* it becomes one.
