There's a parser for the available record provided by the
AptPkg::PkgRecords class.

Get an object from $cache->packages, and use the lookup method.

--bod

#!/usr/bin/perl

use AptPkg::Cache;

my $cache = AptPkg::Cache->new;
my $packages = $cache->packages;

for (@ARGV)
{
    my $p = $packages->lookup($_) or next;
    print "$_\t$p->{SourcePkg}\n";
}
