Overview

An abstract class from which to subclass specific HTML matchers.

A subclass is initialized with a selector and an optional matcher. The selector is an HTML path specification used to collect elements from the document. If initialized with a matcher, the matcher is used to return match information from the elements; else the inner HTML is returned. Subclasses decide how the selector will collect elements.
