我正在尝试从XML文件中获取HTML代码，而我所得到的只是单个元素。
XML示例：
<?xml version="1.0" encoding="ISO-8859-1"?>
<websites>
<website name="1">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title/>
</head><body>Sample Content.....</body>
</html>
</website>
</websites>
我需要一个仅包含html这样的字符串
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title/>
</head><body>Sample Content.....</body>
</html>
from bs4 import BeautifulSoup
example = """
<?xml version="1.0" encoding="ISO-8859-1"?>
<websites>
<website name="1">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title/>
</head><body>Sample Content.....</body>
</html>
</website>
</websites>
"""
soup = BeautifulSoup(example)
html = soup.find('html')
print(html)
