使用python修改目录中的多个.xml文件

import os
import xml.etree.ElementTree as ET

def modify_xml(file_path):
    tree = ET.parse(file_path)
    root = tree.getroot()
    
    # 在这里进行对.xml文件的修改操作，例如修改元素的值、添加新元素等
    
    tree.write(file_path)

def modify_xml_files(directory):
    for root, dirs, files in os.walk(directory):
        for file in files:
            if file.endswith(".xml"):
                file_path = os.path.join(root, file)
                modify_xml(file_path)

directory = "目录路径"
modify_xml_files(directory)
