hi all,

i have an hash like this,

Testcase => 
{'comp' 
   => {'cmd' 
        => {'tc1' 
            => {platform_type => 'all',
                testsuite_type => 'all',
                view => 'private'},
            'tc2' 
            => {platform_type => 'all',
                testsuite_type => 'all',
                view => 'private'}
           }
      }
}
[download]

I delete a key/ value pair in the hash like this,

delete $hoh{$comp}{$cmd}{$tc1};
[download]

But when the value for a key becomes empty, i need to delete that also. How do i delete the key also?
After deleting both 'tc1' and 'tc2' key/value pair, the hash looks like,

Testcase => 
{'comp' 
   => {'cmd' 
        => {}
      }
}
[download]

But actually for "cmd", value is empty. So I would like to remove that. And obviously, "comp" value is also empty, so that also needs to be removed.

thanks
rsennat
