使用beautifulsoup python更改内部标签的文本

Question

我想更改inner text使用Beautifulsoup.

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 获得了标签：

HTMLDocument.find(id='websiteName')

但我无法更改inner text标签的：

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

尝试更改字符串元素：

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>
