Question

我如何抓取此html？

<h3>
<span class="method">GET&nbsp;</span>
[/r/
<em class="placeholder">subreddit</em>
]/api/user_flair
<span class="oauth-scope-list"><a href="https://github.com/reddit/reddit/wiki/OAuth2"><span class="api-badge oauth-scope">flair</span></a>
</span>
</h3>

是否有任何方法可在span标签下获取文本。我知道使用next或next_sibling可以得到下一个文本。但是是否还有其他解决办法，例如h3.span

这样您就可以抓到text

from bs4 import BeautifulSoup
soup = BeautifulSoup("""<h3>
                    <span class="method">GET&nbsp;</span>
                    [/r/
                    <em class="placeholder">subreddit</em>
                    ]/api/user_flair
                    <span class="oauth-scope-list"><a href="https://github.com/reddit/reddit/wiki/OAuth2"><span class="api-badge oauth-scope">flair</span></a>
                    </span>
                    </h3>""")
api_badges = soup.find_all('span', {'class': 'api-badge oauth-scope'})
api_badges_txt = [api_badge.text for api_badge in api_badges]

输出为

['flair']

如果您使用

add_space = soup.find('em').next_sibling.replace('\n', '').strip()
soup.find('h3').get_text(strip=True).replace(add_space, add_space + ' ')

您得到'GET[/r/subreddit]/api/user_flair flair'

如何在BeautifulSoup4中刮除结束标记旁边的文本？
