Subject: Re: Ruby in XML.

I hate to break this to you John, but the link you posted is to a blank 
wiki page. Perhaps you got the wrong link? The page 
http://www.rubygarden.org/ruby?RubyInXML doesn't exist.

Yes, you end up with a hairy state machine, but it doesn't mean you lose 
the one-line StreamParser.

Cheers
