No, I don't think it's rocket science. It's just regexps to parse
hierarchies -- yes, it was essentially what we were doing. Unfortunately,
we were using esoteric proprietary data structures rather than XML. On
the other hand, the stuff we were doing had to work really fast so maybe
XML would've been impractical.
In general, 'though, the entire concept of applying regular expression
technology to parsing XML hierarchies seems really great. It adds far
more generality and compactness, especially if it can be Perl-style
regexps (which are quite powerful).
