2023-01-31 04:01:25 爬虫报文之三

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：

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)
