Well the metadata is just xml, you can parse that with whatever, but if
you want to use the yum routines to do it you should be able to this:
import yum
my = yum.YumBase()
my.doConfigSetup()
my.doRepoSetup(thisrepo='the name or glob of the repos you want to look
through)
my.doSackSetup(thisrepo='the name or glob of the repos you want to look
through)
for package_object in my.pkgSack:
print package_object
that should give you the list of all the packages in the repo.
and for more examples like this one - take a look at the yum-utils
programs.
