array1 = {"remarks"=>"remarks-1", "remarksbox"=>"hello"},{"remarks"=>"remarks-2", "remarksbox"=>"hello1"},
{"remarks"=>"remarks 3", "remarksbox"=>"hello2"},{"remarks"=>"remarks 4", "remarksbox"=>"hello1"}

require an output like this

array2 = {"remarks"=>"remarks-1", "remarksbox"=>"hello", "remarks"=>"remarks-2", "remarksbox"=>"hello1",
      "remarks"=>"remarks 3", "remarksbox"=>"hello2", "remarks"=>"remarks 4", "remarksbox"=>"hello1" }

another array3 consists {"remarks", "remarksbox"}

I need to match the values in array3 to array1, so I can get the values pointed by the keys
array3 is an array of keys
array is an array of {key1->value1, key2->value2}
