在 ElementTree 中使用 XPath 查找嵌套元素

Question

给定以下 xml 示例，我如何打印 Actor 名称及其位置？

我希望输出为：

约翰·克里斯俄亥俄州艾力克科罗拉多

<?xml version="1.0"?>
<actors xmlns:fictional="http://characters.example.com"
        xmlns="http://people.example.com">
    <actor>
        <name>John Cleese</name>
        <fictional:character>Lancelot</fictional:character>
        <fictional:character>Archie Leach</fictional:character>
        <Location>
            <State>
                <name>Ohio</>
            </State>
        </Location>
    </actor>
    <actor>
        <name>Eric Idle</name>
        <fictional:character>Sir Robin</fictional:character>
        <fictional:character>Gunther</fictional:character>
        <fictional:character>Commander Clement</fictional:character>
        <Location>
            <State>
                <name>Colorado</>
            </State>
        </Location>
    </actor>
</actors>

我试过下面的代码，但它只打印演员的名字，不打印州名

import xml.etree.ElementTree as ET

tree = ET.parse('Actors.xml')
root = tree.getroot()

root = fromstring(xml_text)
for actor in root.findall('{http://people.example.com}actor'):
    name = actor.find('{http://people.example.com}name')
    print(name.text)
    for state in actor.findall('{http://characters.example.com}state'):
        print(' |-->', state.text)

Answer 1

这样试试：

actors = root.findall('.//{*}actor')
for actor in actors:
    name = actor.find('./{*}name')
    location = actor.find('./{*}Location//{*}name')
    print(name.text, location.text)

输出：

John Cleese Ohio
Eric Idle Colorado
