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 xminidom
from 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].data
if __name__ == '__main__':
v = introduce_args("modbus_ip") # 输入想要查询的name，获取value
print(v)
