来自 html 和 BeautifulSoup 的文本分类
Text classification from html with BeautifulSoup
我已经获得了 html 页面源代码，然后使用 'html5lib' 和 BeautifulSoup 解析了它。
我有这样的东西：

我正在尝试专门提取 href 中存在的 [51.5176183, -0.0967782] 的经度和纬度。
我试过使用类似于 .text 方法的 .href 方法，但是当我使用 .href 时返回 'None'。你能告诉我如何从 href body 中提取这两个值吗？
运行 html 代码上的 .text 方法返回如下输出：
Museum of London 4,6(13 898) · Museum · 150 London Wall · The history of London from antiquity to today · Closing: 17:00
根据你的问题，我使用 split() 方法得到想要的输出。
