Sort of.  I shouldn't have said "HTML Parser2".  The right name seems to 
be ruby-htmltools.  It integrates with REXML and allows you to do this:

parser = HTMLTree::Parser.new(true, true)
parser.feed(file.readlines.join)
tree = parser.tree.html_node.as_rexml_document
tree.elements.to_a('*/table').each do |element|
  # do something with element
end
