以key=value表示法获取所有xml属性

<student name="John Doe" age="20">
    <grade>A+</grade>
</student>

import xml.etree.ElementTree as ET

def get_xml_attributes(xml_string):
    root = ET.fromstring(xml_string)  # 解析XML字符串

    attributes = []  # 存储属性值

    # 遍历XML元素
    for elem in root.iter():
        if elem.attrib:  # 如果元素有属性
            for key, value in elem.attrib.items():  # 获取所有属性
                attributes.append(f"{key}={value}")  # 添加到属性列表中

    return attributes

# 示例XML字符串
xml_string = '''
<root>
    <element1 attribute1="value1" attribute2="value2"></element1>
    <element2 attribute3="value3"></element2>
</root>
'''

attributes = get_xml_attributes(xml_string)

for attribute in attributes:
    print(attribute)

attribute1=value1
attribute2=value2
attribute3=value3
