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 ET

tree = 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 ETimport requestsr = 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)
