python xml dom clone_python的xml.dom学习笔记

#coding=utf-8

#解析xml文件中的所有的link标签

from xml.dom import minidom

from xml.dom.minidom import getDOMImplementation

doc=minidom.parse("d:\\hello.html")

nodes=doc.getElementsByTagName("link")

for node in nodes:

print "

print "type=\"",node.getAttribute("type"),"\"",

print "rel=\"",node.getAttribute("rel"),"\"",

print "href=\"",node.getAttribute("href"),"\"",

print "/>"

print "通过另外一种方式获得link标签"

linknodes=doc.getElementsByTagName("link")

for i in range(len(linknodes)):

print linknodes[i].getAttribute("type"),

print linknodes[i].getAttribute("rel"),

print linknodes[i].getAttribute("href")

#操作节点

node=linknodes[0]

print dir(node)

print node.parentNode

print node.prefix

print node.nodeType,node.nodeValue,node.nodeName

print node.localName

print node.childNodes

print node.firstChild,node.lastChild

print node.attributes

print node.namespaceURI

print node.nextSibling

print "--"*10

print node.tagName

print "==="*20

impl=getDOMImplementation()

newdoc=impl.createDocument(None , "some_tag", None)

top_element=newdoc.documentElement

node1=newdoc.createTextNode("node1")

node2=newdoc.createTextNode("node2")

node3=newdoc.createTextNode("node3")

top_element.appendChild(node1)

top_element.appendChild(node2)

top_element.appendChild(node3)

top_element.removeChild(node3)

top_element.insertBefore(node3,node2)

print top_element.childNodes

运行结果:
