从树状结构递归地创建xml

import xml.etree.ElementTree as ET

def create_xml_from_tree(tree):
    root = ET.Element(tree['name'])
    for key, value in tree.items():
        if key != 'name':
            if isinstance(value, dict):
                child = create_xml_from_tree(value)
                root.append(child)
            else:
                root.set(key, str(value))
    return root

tree_data = {
    'name': 'root',
    'attribute1': 'value1',

    'child1': {
        'name': 'child1',
        'attribute3': 'value3'

xml_tree.write('output.xml')
