因此，我尝试使用Beautiful Soup对本网站http://www.killedbypolice.net/kbp2013.html进行一些网络抓取，并访问表中的数据。我当前的代码是：
url = "http://www.killedbypolice.net/kbp2013.html"
page = urllib.request.urlopen(url)
soup = BeautifulSoup(page, "html.parser")
data = soup.find_all('table')
data[0]
但是...我遇到了最大递归深度运行时错误。我不确定如何访问表中保存数据的“ td”字段。谢谢
该错误是因为HTML是非常糟糕的格式，你RuntimeError: maximum recursion depth exceeded创造了汤对象既lxml和html.parser，唯一的解析器，在所有的作品是html5lib：
html = requests.get("http://www.killedbypolice.net/kbp2013.html").content
soup = BeautifulSoup(html, "html5lib")
# get all the table rows
table = soup.find("table")
可以得到表格：
<table background="/kbp/bg1.jpg" border="1" cellpadding="0" cellspacing="0" width="100%">
<tbody><tr><td><img src="http://www.killedbypolice.net/size.jpg" width="185"/><br/><b><center># since Jan 1st '14</center></b></td>

<td><b><center>g/r</center></b></td>

但是接下来是对find_all的简单调用：
print(table.find_all("tr"))
给你：
AttributeError: 'NoneType' object has no attribute 'next_element'
html只是一团糟，不幸的是，我看不到用bs4解析它的简单方法，这可能是您需要使用某些正则表达式的罕见情况之一。
