match

Matches an element against the selector.

For a simple selector this method returns an array with the element if the element matches, nil otherwise.

For a complex selector (sibling and descendant) this method returns an array with all matching elements, nil if no match is found.

Use +first_only=true+ if you are only interested in the first element.

For example:

if selector.match(element)
  puts "Element is a login form"
end
