python - 在 BeautifulSoup 中将 替换为 href

Question

content='<p>Hello, the web site is <a href="https://www.google.com">Google</a></p>. <p>The search engine is <a href="https://www.baidu.com">Baidu</a></p>.'
soup = BeautifulSoup(content, 'html.parser')

现在我想替换整个<a> </a>以及href中的url地址。所以我想得到预期的结果:

Hello, the web site is https://www.google.com. The search engine is https://www.baidu.com.

谁能提供解决方案吗？

Answer 1

首先找到a并获取href，然后您可以将href添加到前一个兄弟并删除a

from bs4 import BeautifulSoup

content='<p>Hello, the web site is <a href="https://www.google.com">Google</a></p>. <p>The search engine is <a href="https://www.baidu.com">Baidu</a></p>.'
soup = BeautifulSoup(content, 'html.parser')

# find all `a`
all_a = soup.findAll('a')

for a in all_a:
    # find `href` in `a`
    href = a['href']

    #print('--- before ---')
    #print(soup)

    # add `href` to `previousSibling`
    a.previousSibling.replaceWith(a.previousSibling + href)

    # remove `a`
    a.extract()

    #print('--- after ---')
    #print(soup)

print(soup)

'<p>Hello, the web site is https://www.google.com</p>. <p>The search engine is https://www.baidu.com</p>.'
