from bs4 import BeautifulSoup

with open('file.xml', 'r') as file:
    xml_data = file.read()
soup = BeautifulSoup(xml_data, 'xml')

node = soup.find('node_name')

# 更新节点的文本内容
node.string = 'new_text_content'

# 更新节点的属性
node['attribute_name'] = 'new_attribute_value'

with open('file.xml', 'w') as file:
    file.write(str(soup))
