PHP tool for parsing RSS1.0?

[kellan <kellan@protest.net>]

I've spent most of the morning searching for a tool, in PHP, that parses
RSS1.0, without much success.  I'm wondering does this ellusive beast not
exist, or have I simply not found it?

I found an article[1] on using PHP's expat functionsto parse RSS1.0, which
was good, but it threw away most of the interesting data.  A good place to
start from, but I'm hoping there is something better.

Beyond that, I just found lots and los of RSS .9 parsers, both expat, and
regex based.

I'm hoping to find something out there, that given an RSS feed, can
returned a parse data object in some sort of usable format (like a parse
tree), and can cope seeing tags, and namespaces it doesn't recognize.
Much the way Perl's XML::RSS module works.

I know this might be a little off-topic, but none of the PHP communities
seemed like the proper place.

thanks,
kellan
