如何用美汤替换HTML元素的值？

Question

在 html 文件中搜索一些文本 blob 后，如下所示：

s="the Quick brown fox..."

from bs4 import BeautifulSoup
soup = BeautifulSoup(open('file.html'), 'html.parser')
matches = soup.find_all(lambda x: x.text == s)
for match in matches:
    print(match.parent)

<div class="container-box"><div class="title-box">label</div><p span="" style="font-:normal">the Quick brown fox...</p></div>

如何在 html 文件中仅替换匹配条目的 label 字符串？例如，对于上面找到的元素，我想用 tomatoes?

替换 label

<div class="container-box"><div class="title-box">tomatoes</div><p span="" style="font-:normal">the Quick brown fox...</p></div>

到目前为止我试过这个：

在：

matches = soup.find_all(lambda x: x.text == s)
for match in matches:
    target = match.parent.find("div", {"class": "title-box"})
    print(target.replace_with("tomatoes"))

输出：

<div class="title-box">label</div>

Answer 1

试试这个：

for match in matches:
    #target = match.parent.find('div')

    #EDIT
    target = match.parent.select_one('div.title-box')
    target.replace_with("tomatoes")
soup

输出：

<html><body><div class="container-box">tomatoes<p span="" style="font-:normal">the Quick brown fox...</p></div>
</body></html>
