Example of filtering a Linked List that hold a custom class (Tango)

[JJDuck via Digitalmars-d-learn]

let say I have a Linked List(tango) that holds custom class and 
how do I filter the LinkedList to extract the items that I want 
according to a particular field (a integer field) from my custom 
class?

Is it easier to do it using phobos' Array?
If it does, care to have an example on Phobos too?
Thanks a lot
