Overview

A Result represents a collection of Node::Element on the page. It is possible to interact with this collection similar to an Array because it implements Enumerable and offers the following Array methods through delegation:

  • each()

  • at()

  • size()

  • count()

  • length()

  • first()

  • last()

  • empty?()
