如何使用BeautifulSoup来获得深度嵌套的DIV值？ [英] How can I use BeautifulSoup to get deeply nested div values?

问题描述

我需要得到的值深层嵌套＆LT;跨度＆GT; 在DOM结构，看起来像这样的元素：

I need to get the values of deeply nested <span> elements in a DOM structure that looks like this:

<div class="panda">
    <div class="that">
        <ul class="foo">
            <li class="bar">
                <div class="hi">
                    <p class="bye">
                        <span class="cheese">Cheddar</span>

这个问题。

soup.findAll（跨越，{级：奶酪}）

是，有数以百计的网页上跨度元素与一流的奶酪，所以我需要通过类熊猫来过滤。我需要得到值的列表如 [切德，巴马，瑞士]

is that there are hundreds of span elements on the page with class "cheese" so I need to filter them by class "panda". I need to get a list of values like ["Cheddar", "Parmesan", "Swiss"]

推荐答案

使用CSS选择器：

[e.get_text() for e in soup.select('.panda .cheese')]

或者，如果你preFER find_all ：

# Calling a soup or tag is the same as find_all

[e.get_text() for panda in soup('div', {'class': 'panda'}) 
              for e in panda('span', {'class': 'cheese'})]
