Python实现基于XML的配置文件管理

import xml.etree.ElementTree as ET


# 读取XML配置文件
def read_config(file_path):
    tree = ET.parse(file_path)  # 解析XML文件
    root = tree.getroot()  # 获取根节点
    config = {}
    for child in root:
        key = child.tag  # 获取标签名作为配置项的键
        value = child.text  # 获取标签的文本值作为配置项的值
        config[key] = value
    return config


# 写入XML配置文件
def write_config(config, file_path):
    root = ET.Element("config")  # 创建根节点
    for key, value in config.items():
        child = ET.SubElement(root, key)  # 创建配置项的子节点
        child.text = str(value)  # 将配置项的值写入子节点的文本
    tree = ET.ElementTree(root)
    tree.write(file_path, encoding="utf-8")  # 将根节点写入XML文件


# 测试代码
if __name__ == "__main__":
    config_file = "config.xml"  # 配置文件路径

    # 读取配置文件
    config = read_config(config_file)
    print("读取配置文件：")
    for key, value in config.items():
        print(f"{key}: {value}")

    # 修改配置项的值
    config["host"] = "127.0.0.1"
    config["port"] = "8080"

    # 写入配置文件
    write_config(config, config_file)
    print("写入配置文件完成")
