BeautifulSoup找不到所需的div [英] BeautifulSoup can't find required div

问题描述

我一直在尝试获取嵌套的div及其内容，但不能.我想使用class:'box coursebox'访问div.

I have been trying to get at a nested div and its contents but am not able to. I want to access the div with class:'box coursebox'.

response = res.read()
soup = BeautifulSoup(response, "html.parser")    
div = soup.find_all('div', attrs={'class':'box coursebox'})

上面的代码给出了一个div，其中有0个元素，应该为8.这行之前的find_all调用可以正常工作.

The above code gives a div with 0 elements, when there should be 8. find_all calls before this line work perfectly.

感谢您的帮助！

推荐答案

对于具有多个值的属性，Beautiful Soup会将所有值放入列表中.在您的代码中，查找时需要考虑到这一点.

In the case of attributes having more than one value, Beautiful Soup puts all the values into a list. In your code, you need to take this into account when you're doing your lookup.

也许是这样吗?

div = soup.find_all('div', class_="box coursebox"})

请参阅本节的Soup的文档，以获取有关多值属性的更多信息，以及本节，了解有关按类查找元素的详细信息.

Refer to this section of Beautiful Soup's documentation for more information on multi-valued attributes, and this section for details on looking elements up by class.
