[Rpm-metadata] Is there an easy way to get a simple dict of rpm attributes from xml metadata?

So you just want a quick way to say 'if no changes, don't re-index'. I
thought you  were asking for a quick way to really only index the
changed information, instead of re-reading all of it.

The former isn't a big deal - send me a patch and I'll probably pull it
in.

The latter will be difficult to make fast.
