python - 使用 beautifulsoup python 更改内部标签的文本

Question

我想更改使用 Beautifulsoup 获得的 HTML 标签的 inner text。

例子:

<a href="index.html" id="websiteName">Foo</a>

变成:

<a href="index.html" id="websiteName">Bar</a>

我已经设法通过它的 id 获取标签:

HTMLDocument.find(id='websiteName')

但我无法更改标签的内部文本:

print HTMLDocument.find(id='websiteName')

a = HTMLDocument.find(id='websiteName')
a = a.replaceWith('<a href="index.html" id="websiteName">Bar</a>')

// I have tried using this as well
a = a.replaceWith('Bar')

print a

输出:

<a href="index.html" id="websiteName">Foo</a>
<a href="index.html" id="websiteName">Foo</a>

Answer 1

尝试改变字符串元素:

HTMLDocument.find(id='websiteName').string.replace_with('Bar')

---

from bs4 import BeautifulSoup as soup

html = """
<a href="index.html" id="websiteName">Foo</a>
"""
soup = soup(html, 'lxml')
result = soup.find(id='websiteName')

print(result)
# >>> <a href="index.html" id="websiteName">Foo</a>

result.string.replace_with('Bar')
print(result)
# >>> <a href="index.html" id="websiteName">Bar</a>
