如何通过属性获取lxml中所有元素的路径

from lxml import etree

def get_element_paths_by_attribute(root, attribute_name, attribute_value):
    paths = []
    for element in root.iter():
        if attribute_name in element.attrib and element.attrib[attribute_name] == attribute_value:
            path = root.getpath(element)
            paths.append(path)
    return paths

# 示例XML文档
xml = '''
<root>
    <element attribute="value1">
        <subelement attribute="value2"/>
    </element>
    <element attribute="value3"/>
</root>
'''

# 解析XML文档
root = etree.fromstring(xml)

# 获取所有具有attribute="value1"的元素路径
paths = get_element_paths_by_attribute(root, 'attribute', 'value1')

# 打印结果
for path in paths:
    print(path)

/root/element
