Thanks for your quick response Mehul.
Can you suggest me the best option to parse an xml from shell ?
<snip>
Is this what you want?
zgrep checksum /path/to/filename.xml.gz
Yeah, I was looking for something similar
I should have checked before replying.
Some examples in perl and awk are shown here on how to work with xml
files

Before that you could use something like
1. Perl -> http://search.cpan.org/~mikewong/XML-Dumper-0.81/Dumper.pm
2. Python -> http://docs.python.org/release/2.5.2/lib/module-zlib.html
Thanks for these options.
Later today I realized that there is also a sqlite db for the yum/zypper
repo which resides in the client end. Hence I had taken the below
approach.
sqlite3 /var/cache/yum/<reponame>/primary.xml.gz.sqlite 'select pkgId
from packages where location_href like "%ZSI-1.7-2.el5.mdsc.i386.rpm"'
I had also come across xmllint, xmlproc_parse might have also solved my
need.
