Maybe I should extend it to get size data from primary.xml.gz:

<?xml version="1.0" encoding="UTF-8"?>
<metadata packages="10675" xmlns="http://linux.duke.edu/metadata/common" xmlns:rpm="http://linux.duke.edu/metadata/rpm"><package type="rpm">

             ...
  <size package="6440" installed="2122" archive="2380"/><!-- size[@package] is size of the RPM package file -->
