打印html标记的子p元素

Question

我正在使用漂亮的汤打印某些文本从网站外到一个控制台。

我试图打印'p‘标签文本，是’8月‘和'27'，但只有'a’标签包含一个子'img‘标签，但出于某种原因，没有任何打印出来。

这是html代码-(我在我想要的红色文本下划线)

​

<a data-qa="product-card-link" aria-label="Off-Line 'Black Menta' Release Date" class="card-link d-sm-b" href="/gb/launch/t/off-line-black-menta">
    <div class="launch-time ta-sm-l d-sm-h d-md-b z10 mod-bg-grey pt6-sm pl6-sm">
        <div class="launch-caption ta-sm-c">
            <p class="mod-h2 ncss-brand u-uppercase fs19-sm fs28-md fs34-lg " data-qa="test-startDate">Aug</p>
            <p class="mod-h1 ncss-brand test-day fs30-sm fs40-md" data-qa="test-day">28</p>
        </div>
    </div>
    <img alt="Off-Line 'Black Menta' Release Date" class="image-component mod-image-component u-full-width" src="https://secure-images.nike.com/is/image/DotCom/CJ0693_002_A_PREM?$SNKRS_COVER_WD$&amp;align=0,1" srcset="" style="opacity: 1; transition: opacity 1s ease 0s;">
</a>

以下是我尝试过的：

for a in soup.find_all('a', class_='card-link d-sm-b'):
    if a.find('img'):
        for p in a.find_all('p'):
            print(p.text)

您可以使用CSS选择器a.card-link:has(> img):has(p)，它将使用包含直接子<img>和<p>标记的class="card-link"来选择所有的<p>标记(<p>标记可以是任何深度的)：

from bs4 import BeautifulSoup

txt = '''
<a data-qa="product-card-link" aria-label="Off-Line 'Black Menta' Release Date" class="card-link d-sm-b" href="/gb/launch/t/off-line-black-menta">
    <div class="launch-time ta-sm-l d-sm-h d-md-b z10 mod-bg-grey pt6-sm pl6-sm">
        <div class="launch-caption ta-sm-c">
            <p class="mod-h2 ncss-brand u-uppercase fs19-sm fs28-md fs34-lg " data-qa="test-startDate">Aug</p>
            <p class="mod-h1 ncss-brand test-day fs30-sm fs40-md" data-qa="test-day">28</p>
        </div>
    </div>
    <img alt="Off-Line 'Black Menta' Release Date" class="image-component mod-image-component u-full-width" src="https://secure-images.nike.com/is/image/DotCom/CJ0693_002_A_PREM?$SNKRS_COVER_WD$&amp;align=0,1" srcset="" style="opacity: 1; transition: opacity 1s ease 0s;">
</a>'''

soup = BeautifulSoup(txt, 'html.parser')

for a in soup.select('a.card-link:has(> img):has(p)'):
    all_p = [p.get_text(strip=True) for p in a.select('p')]
    print(all_p)

指纹：

['Aug', '28']

编辑:要获取产品的日期和名称，可以使用以下脚本：

import requests
from bs4 import BeautifulSoup


url = 'https://www.nike.com/gb/launch?s=upcoming'
soup = BeautifulSoup(requests.get(url).content, 'html.parser')

for d in soup.select('div.launch-caption'):
    print(d.get_text(strip=True, separator=' '), 
        d.find_next('h3').get_text(strip=True), 
        d.find_next('h6').get_text(strip=True))
