==== Examples

\Test two HTML strings for equivalency (e.g., identical up to reordering of attributes) 
def assert_dom_equal(expected, actual, message = "")
  expected_dom = HTML::Document.new(expected).root
  actual_dom   = HTML::Document.new(actual).root

def assert_dom_not_equal(expected, actual, message = "")


assert_dom_not_equal 'Apples', link_to("Oranges", "http://www.example.com")
# assert that the referenced method does not generate the specified HTML string

==== Examples

The negated form of +assert_dom_equivalent+.

  expected_dom = HTML::Document.new(expected).root
  actual_dom   = HTML::Document.new(actual).root
