BeautifulSoup is choking on jQuery script, any known workaround?

I'm giving BeautifulSoup an html document and simply by constructing a BeautifulSoup object instance with the full html, it seems to choke on the following line of a jQuery script that's embedded within the html:

        var txt = "Logged in as: <a href=\"http://somedomain.com/the-blah/\">" + uname + "</a> <small>(<a href=\"http://somedomain.com/the-blah/\">The Blah</a> | <a href=\"http://somedomain.com/the-blah/?action=logout\">logout</a>)</small>";

The full stack trace for the error is the following:

From what I can glean it has something to do with the angle brackets being within quotes, it seems to be thrown off by this. What kind of work around is there, or is there another library that handles these edge cases better? Or alternatively, is there a way to tell it to ignore all javascript content?


the easiest way would probably be to delete all the scripts. see the section Removing Elements in the documentation: http://www.crummy.com/software/BeautifulSoup/documentation.html#Removing%20elements
