def pseudo?
  state_based_pseudo_selectors.any? {|p| selector_text.end_with? ":#{p}"} 
end

#search ⇒ Object

A slightly adjusted version of the selector_text that should be used for finding nodes. Will remove the pseudo selector and prepend ‘body ’.

def search
  selector_text.dup.tap do |s|
    state_based_pseudo_selectors.each {|p| s.gsub! /:#{p}$/, ''}
      s.insert(0, 'body ') unless s =~ /^body/
  end
end

#state_based_pseudo_selectors ⇒ Object

A list of state based pseudo selectors (like hover) that should be handled based on the pseudo option. Unlike position-based pseudo selectors (like :first-child) which once resolved to the correct node effectively get inlined like a normal selector.
