Select elements where attribute is non-empty

Question

Suppose I have the following:

Unknown
Known 123

Is there a way

Answer 1

This works, if you don't mind doing things slightly backwards and you need it to work in browsers that don't support :not:

div[data-pid] {
    color: green;
}

div[data-pid=""] {
    color: inherit;
}

That will make all the divs with non-empty data-pids green.
