如何在没有任何标识的情况下从代码中选择第二个 div？

Question

我不明白我需要做什么才能使用 bs4 将第二个 div 放入第二个 div。我需要获取带有日期的 div。感谢您的帮助。这是代码：<div class="featured-item-meta">    <div><strong>Published:</strong></div>    <div>October 14, 2015</div>    <ul class="creatorList">        <li>            <div><strong>Writer:</strong></div>            <div><a href="https://www.marvel.com/comics/creators/10329/g_willow_wilson">G. Willow Wilson</a>, <a href="https://www.marvel.com/comics/creators/12441/marguerite_bennett">Marguerite  Bennett</a></div>        </li>        <li>            <div><strong>Cover Artist:</strong></div>            <div><a href="https://www.marvel.com/comics/creators/8825/jorge_molina">Jorge  Molina</a></div>        </li>    </ul></div>

Answer 1

使用 bs4 4.7.1 + 这很容易。您可以使用:hasand:contains获取具有包含字符串div的子项的父项，然后使用相邻的兄弟组合器获取下一个。strongPublished:div

from bs4 import BeautifulSoup

html = '''

<div class="featured-item-meta">

    <div><strong>Published:</strong></div>

    <div>October 14, 2015</div>

    <ul class="creatorList">

        <li>

            <div><strong>Writer:</strong></div>

            <div><a href="https://www.marvel.com/comics/creators/10329/g_willow_wilson">G. Willow Wilson</a>, <a href="https://www.marvel.com/comics/creators/12441/marguerite_bennett">Marguerite  Bennett</a></div>

        </li>

        <li>

            <div><strong>Cover Artist:</strong></div>

            <div><a href="https://www.marvel.com/comics/creators/8825/jorge_molina">Jorge  Molina</a></div>

        </li>

    </ul>

</div>

'''

soup = bs(html, 'lxml')

print(soup.select_one('div:has(strong:contains("Published:")) + div').text)

Answer 2

这是一个解决方法

text = '<div class="featured-item-meta">\

<div><strong>Published:</strong></div>\

<div>October 14, 2015</div>\

<ul class="creatorList">\

    <li>\

        <div><strong>Writer:</strong></div>\

        <div><a href="https://www.marvel.com/comics/creators/10329/g_willow_wilson">G. Willow Wilson</a>, <a href="https://www.marvel.com/comics/creators/12441/marguerite_bennett">Marguerite  Bennett</a></div>\

    </li>\

    <li>\

        <div><strong>Cover Artist:</strong></div>\

        <div><a href="https://www.marvel.com/comics/creators/8825/jorge_molina">Jorge  Molina</a></div>\

    </li>\

</ul>\

</div>'

soap = BeautifulSoup(text,'html.parser')

print(soap.find('div',attrs={'class':'featured-item-meta'})\

          .find_all('div')[1].text)

输出：

October 14, 2015

Answer 3

from  bs4 import BeautifulSoup as bsp

s = '''

<div class="featured-item-meta">

    <div><strong>Published:</strong></div>

    <div>October 14, 2015</div>

    <ul class="creatorList">

        <li>

            <div><strong>Writer:</strong></div>

            <div><a href="https://www.marvel.com/comics/creators/10329/g_willow_wilson">G. Willow Wilson</a>, <a href="https://www.marvel.com/comics/creators/12441/marguerite_bennett">Marguerite  Bennett</a></div>

        </li>

        <li>

            <div><strong>Cover Artist:</strong></div>

            <div><a href="https://www.marvel.com/comics/creators/8825/jorge_molina">Jorge  Molina</a></div>

        </li>

    </ul>

</div>

'''

print(bsp(s).find('div').findChildren('div')[1])
