    Which HTMLParser?

    The library docs show that there is an HTMLParser module and an
    htmllib module, both of which apparently contain classes named
    "HTMLParser ". There is a bit of decription of differences, but it
    still doesn't seem clear to me what the intent is.

    Which one is the best choice for parsing arbitrary real-life Web
    pages? I get the feeling that maybe the HTMLParser module is the more
    recent, more practical utility, while the htmllib version is the older
    one, retained for backward compatibility, but I'm not sure. The docs
    don't exactly say that.

    Any recommendations or clarifications of what's going on would be
    helpful.

    Thanks.

      If you are not sure that your source is valid HTML, use SGML parser
      instead. Personally I recommend F. Lundh's sgmlop -- fast, robust and
      well-written piece of software, real Meisterstueck. Works perfectly on
      Unix, Windows and IBM iSeries (formerly AS/400).

          I think the intent is to use HTMLParser. Its newer, and its documentation
          doesn't scare you off with phrases like "HTML 2.0" and "SGML" :-)

          Neither! Real-life web pages are typically not HTML-parseable. Try tyding
          it up a bit first. See http://groups.google.nl/groups?th=58cd394d2e71137f
