ClosestMatcher gets the first element that matches the matcher by testing the element itself and traversing up through its ancestors in the DOM tree.

(m Matcher)

// ClosestMatcher gets the first element that matches the matcher by testing the
// element itself and traversing up through its ancestors in the DOM tree.
func (s *Selection) ClosestMatcher(m Matcher) *Selection {
	return pushStack(s, mapNodes(s.Nodes, func(i int, n *html.Node) []*html.Node {
		// For each node in the selection, test the node itself, then each parent
		// until a match is found.
		for ; n != nil; n = n.Parent {
			if m.Match(n) {
				return []*html.Node{n}
			}
		}
		return nil
	}))
}

// ClosestNodes gets the first element that matches one of the nodes by testing the
// element itself and traversing up through its ancestors in the DOM tree.
