如何在Python中编辑XML文件？

import xml.etree.ElementTree as ET

# 创建XML文件
root = ET.Element("root")
tree = ET.ElementTree(root)

# 添加子元素
child1 = ET.SubElement(root, "child1")
child1.text = "This is child 1"

child2 = ET.SubElement(root, "child2")
child2.text = "This is child 2"

# 修改元素内容
child1.text = "Updated child 1"

# 保存XML文件
tree.write("example.xml")
