# It can be either at the Tokenizer stage:
#
# HTMLParser.parse(html, :tokenizer => HTMLSanitizer)
#
# or, if you already have a parse tree (in this example, a REXML tree),
# at the Serializer stage:
#
# tokens = TreeWalkers.getTreeWalker('rexml').new(tree)
# HTMLSerializer.serialize(tokens, {:encoding=>'utf-8',
