如何在python中创建xml文档

import xml.etree.ElementTree as ET

# 创建根元素
root = ET.Element("root")

# 创建子元素
child1 = ET.SubElement(root, "child1")
child2 = ET.SubElement(root, "child2")

# 为子元素添加文本内容
child1.text = "Hello, world!"
child2.text = "Python is awesome!"

# 创建XML文档
tree = ET.ElementTree(root)

# 将XML文档保存到文件中
tree.write("example.xml")

<root>
 <child1>Hello, world!</child1>
 <child2>Python is awesome!</child2>
</root>
