如何阻止BeautifulSoup将HTML实体解码为符号

from bs4 import BeautifulSoup

html = "<p>&lt;Hello&gt;</p>"
soup = BeautifulSoup(html, "html.parser")
print(soup.p.string)  # 输出: <Hello>

from bs4 import BeautifulSoup

html = "<p>&lt;Hello&gt;</p>"
html = html.replace("<", "&lt;").replace(">", "&gt;")
soup = BeautifulSoup(html, "html.parser")
print(soup.p.string)  # 输出: &lt;Hello&gt;

from bs4 import BeautifulSoup
from bs4 import NavigableString

def contains_entity(text):
    return isinstance(text, NavigableString) and ("&" in text)

html = "<p>&lt;Hello&gt;</p>"
soup = BeautifulSoup(html, "html.parser")
filtered_elements = soup.find_all(contains_entity)
for element in filtered_elements:
    print(element.string)  # 输出: &lt;Hello&gt;
