For yum I'd just do something like:
% cat /tmp/pkgs-xml.py
#! /usr/bin/python -tt
import sys
import yum
yb = yum.YumBase()
yb.conf.cache = 1
for pkg in yb.rpmdb.returnPackages(patterns=sys.argv[1:]):
print """\
<package name="%s">
<epoch>%s</epoch>
<version>%s</version>
<release>%s</release>
<arch>%s</arch>
<summary>%s</summary>
<vendor>%s</vendor>
</package>
""" % (pkg.name, pkg.epoch, pkg.version, pkg.release, pkg.arch,
yum.misc.to_xml(pkg.summary), yum.misc.to_xml(pkg.vendor))
...but if you can't rely on yum you could copy and paste (or rewrite)
all the yum specific bits and just use rpm-python.
