XML 处理脚本仅列出一个元素，但有多个元素要列出

Question

我编写了一个简单的 Python 脚本来打印与父元素属性关联的所有包名称的 XML 数据：Security Advisory。import xml.etree.ElementTree as ETtree = ET.parse('errata.xml')root = tree.getroot()for security in root.findall("*[@type='Security Advisory']"):    packages = security.find('packages')    print(packages.text)但是，该脚本仅打印出第一个包名称，但有多个包名称。我将如何获取属于父属性的所有包名称：Security Advisory？

Answer 1

下面（似乎有效）

import xml.etree.ElementTree as ET

import requests

r = requests.get('https://cefs.b-cdn.net/6010e333a44911e24b5112e23acbb346ae15f7b7/errata.latest.xml')

if r.status_code == 200:

    root = ET.fromstring(r.content)

    sec_elements = [e for e in root.findall("*[@type='Security Advisory']") if

                    e.find('os_release') is not None and int(e.find('os_release').text) > 6]

    for ele in sec_elements:

        packages = ele.findall('./packages')

        for p in packages:

            print(p.text)
