迭代字符串XML以读取节点内部的内容

import xml.etree.ElementTree as ET

def iterate_xml(xml_string):
    root = ET.fromstring(xml_string)
    iterate_node(root)

def iterate_node(node):
    # 读取节点内容
    if node.text:
        print("节点内容:", node.text)
    
    # 遍历子节点
    for child in node:
        print("节点标签:", child.tag)
        print("节点属性:", child.attrib)
        iterate_node(child)

# XML字符串示例
xml_string = '''
