Question

我正在为BeautifulSoup提供一个html文档，只需用完整的html构建一个BeautifulSoup对象实例，它似乎扼杀了嵌入在html中的jQuery脚本的以下行：

        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>";

错误的完整堆栈跟踪如下：

从我可以收集的内容中，它与尖括号在引号内有关，似乎被它抛弃了。那里有什么样的工作，还是有另一个库可以更好地处理这些边缘情况？或者，有没有办法告诉它忽略所有的javascript内容？

最简单的方法可能是删除所有脚本。请参阅文档中的删除元素部分：http://www.crummy.com/software/BeautifulSoup/documentation.html#Removing%20elements

BeautifulSoup在jQuery脚本上窒息，任何已知的解决方法？
