python 对xml解析 python 对xml解析的示例

import xml.dom.minidom

#负责解析xml文件的包

from xml.dom.minidom import parse

​

#使用minidom打开xml文件

DOMTree = xml.dom.minidom.parse("D30_1_XmlNameSpace.xml")

print(DOMTree)#将该XML文件定义为一个对象

#得到文档对象

doc = DOMTree.documentElement#打印出了带有根目录的名字的对象

print(doc)

​

#显示子元素

for ele in doc.childNodes:

  if ele.nodeName == "student:Name":

    print("=======Node:{0}=======".format(ele.nodeName))

    print(doc.childNodes)

  if ele.nodeName == "Age":

    print(ele.getAttribute("jio"))#获取某一节点的属性值

mport xml.etree.ElementTree

root = xml.etree.ElementTree.parse("D30_1_XmlNameSpace.xml")

nodes = root.getiterator()

for node in nodes:

  print("{0}---{1}".format(node.tag,node.text))

print("===========================================")

ele_room_name = root.find("Location")

print(type(ele_room_name))

print("{0}----{1}".format(ele_room_name.tag,ele_room_name.text))

print("===========================================")

ele_room_name2 = root.findall("{http://my_room}Name")#这里如果使用“room:Name”是解析不出来的

print(ele_room_name2)

for ele in ele_room_name2:

  print("{0}----{1}".format(ele.tag,ele.text))

ele_room_name2 = root.findall("room:Name")

print(ele_room_name2)

for ele in ele_room_name2:

  print("{0}----{1}".format(ele.tag,ele.text))
