Subject: Multidimensional hash - get all not blank keys

Hello.

I have this Hash.

result={"1"=>{"6"=>"",
        "7"=>"",
        "8"=>"",
        "1"=>"Value1",
        "2"=>"",
        "3"=>"Value2",
        "4"=>"",
        "5"=>""},
      "2"=>{"6"=>"",
        "7"=>"",
        "8"=>"Value3",
        "1"=>"",
        "2"=>"",
        "3"=>"",
        "4"=>"",
        "5"=>""},
      "3"=>{"6"=>"",
        "7"=>"",
        "8"=>"",
        "1"=>"",
        "2"=>"",
        "3"=>"",
        "4"=>"",
        "5"=>""},
      "4"=>{"6"=>"",
        "7"=>"",
        "8"=>"Value4",
        "1"=>"",
        "2"=>"Value5",
        "3"=>"",
        "4"=>"",
        "5"=>""}
}


Is it possible to get all keys with a the value.
1,[1 => Value1]
1,[3 => Value2]
2,[8 => Value3]
4,[8 => Value4]
4,[2 => Value5]
