如何从Google App Engine应用程序解析XML？

import xml.etree.ElementTree as ET

def parse_xml(xml_data):
    root = ET.fromstring(xml_data)
    for child in root:
        print(f"{child.tag}: {child.text}")

from google.appengine.api import urlfetch

def get_and_parse_xml(url):
    result = urlfetch.fetch(url)
    if result.status_code == 200:
        parse_xml(result.content)
    else:
        print(f"Error: {result.status_code}")

url = "https://example.com/data.xml"
get_and_parse_xml(url)
