How to retrieve data on nested data firebase

My database looks like this

app
   -data
      -Kc2Um3N
        -profile
          -something
        -attribute
          -tfyRzLa3
             -**name**
       -Kc2Um3N
         -profile
           -something
         -attribute
           -tfyRzLa3
             -**name**
   -metadata
      -something

I want to access name in the app>data>atribute>name. How do i do this?
