通过xml.dom.minidom解析

XML中的内容：

<?xml version="1.0" encoding="UTF-8" ?><configuration> <property> <name>modbus_ip</name> <value>127.0.0.1</value> <describe>name的描述内容</describe> </property></configuration>

Python3 脚本内容：

import xml.dom.minidom as xminidomfrom os.path import dirname, abspath# 解析XML文件，获取相应数据def introduce_args(input_name): """ :param input_name: string :return: string """ setting_path = dirname(dirname(abspath(__file__))) + '/conf/setting.xml' dom_tree = xminidom.parse(setting_path) collection = dom_tree.documentElement properties = collection.getElementsByTagName("property") # 找到标签是property的 for message in properties: name = message.getElementsByTagName('name')[0] # 在标签是property的里面找标签是name的 if name.childNodes[0].data == input_name: value = message.getElementsByTagName('value')[0] return value.childNodes[0].dataif __name__ == '__main__': v = introduce_args("modbus_ip") # 输入想要查询的name，获取value print(v)
