Is there a HTML parser who can reconstruct the original html EXACTLY?

At the risk of promoting unfashionable DOM technologies, you can at
least serialise fragments of the DOM in libxml2dom [1]:

  import libxml2dom
  d = libxml2dom.parseURI("http://www.diveintopython.org/", html=1)
  print d.xpath("//p")[7].toString()

Storage and retrieval of the original line and offset information may
be supported by libxml2, but such information isn't exposed by
libxml2dom.
