在 BeautifulSoup 中用 <tag>substring</tag> 替换 substring

Question

我正在尝试修改现有的 html 文件，以便将特定关键字打印为强关键字（无论它们出现在何处）。

我的尝试：

from bs4 import BeautifulSoup as soup
txt = """<html><head><style></style></head><body><h2>"This is my keyword</h2><table><tr><td>This could be another instance of the keyword.</td></tr></table></body></html>"""

buzz_words = ["keyword", "apples"]

htmlSoup = soup(txt, features="html.parser")
for word in buzz_words:
    target = htmlSoup.find_all(text=re.compile(r"" + re.escape(word)))
    for v in target:
        v.replace_with(v.replace(word, "".join(["<strong>", word, "</strong>"])))
print(str(htmlSoup))

结果：

This is my &lt ;strong&gt ;keyword&lt ;/strong&gt ;(spaces added by me)

想要的结果：

This is my <strong>keyword</strong>

尝试以下方法

from bs4 import BeautifulSoup as soup

import html

txt = """<html><head><style></style></head><body><h2>"This is my keyword</h2><table><tr><td>This could be another instance of the keyword.</td></tr></table></body></html>"""

buzz_words = ["keyword", "apples"]

htmlSoup = soup(txt, features="html.parser")
for word in buzz_words:
    target = htmlSoup.find_all(text=re.compile(r"" + re.escape(word)))
    for v in target:
        v.replace_with(v.replace(word, "".join(["<strong>", word, "</strong>"])))
print(html.unescape(str(htmlSoup.prettify())))
