One option for you would be to parse the output of rpm -q --queryformat or rpm
-qa --queryformat. For doing this, look at:
* https://metacpan.org/release/IPC-Run
* https://metacpan.org/module/IPC::System::Simple
This functionality may also be provided by librpm (not sure about that) and
there are some rpm-related Perl wrappers for it on CPAN:
https://metacpan.org/search?q=rpm
Mageia Linux ships with perl-RPM2-1.0-5.mga3 and perl-RPM4-0.31-1.mga3 .
I sincerely hope all of this will help you.
