I think blockquote might be handled, and anchors do show their links. Possibly also lists?

I think Jon Rosebaugh (aka Chairos) ported lxml.html.clean to BeautifulSoup. You couldn't do it without some kind of HTML parser, but BS is an easy install (or even include it, it's just one file). feedparser also includes a cleaner, but IMHO it's a bit more crude. -- Ian Bicking : [EMAIL PROTECTED] : http://blog.ianbicking.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
