通过使用BeautifulSoup选择所有div兄弟姐妹 [英] Select all div siblings by using BeautifulSoup

问题描述

我有一个html文件，其结构如下:

I have an html file which has a structure like the following:

<div>
</div

<div>
</div>

<div>
  <div>
  </div>
  <div>
  </div>
  <div>
  </div>
<div>

<div>
  <div>
  </div>
</div>

我想在不选择第三和第四块嵌套div的情况下选择所有同级div.如果使用find_all()，我会得到所有的div.

I would like to select all the siblings div without selecting nested div in the third and fourth block. If I use find_all() I get all the divs.

推荐答案

您可以找到父元素的直接个子代:

You can find direct children of the parent element:

soup.select('body > div')

获取顶级body标签下的所有div元素.

to get all div elements under the top-level body tag.

您还可以先找到 div，然后使用

You could also find the first div, then grab all matching siblings with Element.find_next_siblings():

first_div = soup.find('div')
all_divs = [first_div] + first_div.find_next_siblings('div')

或者您可以使用 element.children生成器并对它们进行过滤:

Or you could use the element.children generator and filter those:

all_divs = (elem for elem in top_level.children if getattr(elem, 'name', None) == 'div')

其中top_level是直接包含这些div元素的元素.

where top_level is the element containing these div elements directly.
