class Hpricot::Doc
  def select_nodes
    selected = []
    queue = children.reverse
    while node = queue.pop
      selected << node if yield node
      queue.push(*node.children.reverse) if node.respond_to? :children
    end
    selected
  end
end
def Hpricot.orphan_node(node)
  list = node.parent.children
  node.parent = nil
  list.delete(node)
end

doc = Hpricot(open(''filename.html''))
doc.select_nodes { |n| n.comment? }.each { |c| Hpricot.orphan_node(c) }
