def initialize(io, line_terminator, roots, &block)

	@line_terminator = line_terminator
	@io = io

	# Use a push parser so we can fake a single root element
	@parser = Nokogiri::XML::SAX::PushParser.new(Parser.new(FAKEROOT, roots, &block))

	# This is the "root" of the document. We intentionally never close this
	# so that the parser doesn't get mad when it encounters multiple real
	# root elements.
	@parser << "<#{FAKEROOT}>"

end
