请帮我解决这个问题。我有一个具有这种结构的 xml 文件：

我无法获取对象的面积（准确地从文件中获取），我使用这段代码：

for path in Path(file_path).rglob('*.XML'):
with open(path, 'r',encoding='utf-8') as parse:
xml = parse.read()
soup = BeautifulSoup(xml, features="xml")
print(soup.select_one('permitted_use_established by_document'))
print(soup.select_one('area value'))
在这里，我尝试将文件结构放入一个变量中，我成功了，但它在 xml 文件中不起作用。还尝试了地方“soup = BeautifulSoup(xml, features="xml")”，使用了“soup = BeautifulSoup(xml, features="lxml")”，然后给出了“<by_document>Residential Private Sector</by_document>”，但不显示“438”。假设问题出在xml文件的编码上，因为 当我从变量（用 visual studio 代码编写）复制文本并将其粘贴到记事本中并保存在 xml 中时，它搜索没有问题，但是当通过记事本重新保存原始 xml 文件时，它没有提供任何内容。也许这就是问题所在。尝试重装python、visual studio code、lxml、bs4，无果。
原来是用不同的编码
试试这个，添加.text：
