本节主要是讲解在项目中怎么解析获取的xml报文并获取相关字段。
xml解析第三方库学习地址：http://www.runoob.com/python/python-xml.html
xml文件如下：

</Task>解析的代码（中间有部分调试文件）：
#!/usr/bin/python3
#coding:utf-8
from xml.dom.minidom import parse
import xml.dom.minidom
Root = xml.dom.minidom.parse('开机提醒.xml')
# print(dir(DOMTree))
task = Root.documentElement
# print(dir())
for line in task.childNodes:
# print('line.nodeName:',line.nodeName,'line.nodeType:',line.nodeType,'line.nodeValue:',line.nodeValue,'line.normalize:',line.normalize)
# print(len(line))
# print(line)
if 3 == line.nodeType:
continue
if 'Actions' == line.nodeName:
for tmp in line.childNodes:
# print(tmp)
if 3 == tmp.nodeType:
continue
# print(tmp)
for tmp1 in tmp.childNodes:
if 3 == tmp1.nodeType:
continue
for tmp2 in tmp1.childNodes:
# print(tmp2)
# if 3 == tmp2.nodeType:
# continue
print(tmp2.nodeValue)
# for line1 in line.childNodes:
# if 3 == line1.nodeType:
# continue
# # print(line1.nodeName)
# # print(dir(line1))
# for line2 in line1.childNodes:
# if 3 == line2.nodeType:
# continue
# print(line2.nodeValue)
# print(line2.data)效果图：
