The find method of Mojo::DOM
returns a Mojo:::Collection
object, the elements of which are Mojo::DOM
attr is a Mojo::DOM method that cannot be applied to a Mojo::Collection object.
You will have to extract the Mojo::DOM objects from the Mojo::Collection object or use a Mojo::Collection method such as map.
A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
