整理了下，比如叫做 ie.py :

# -*- coding:utf-8 -*-
import time
from win32com.client import DispatchEx

def ExistIE(url):
    ShellWindowsCLSID = '{9BA05972-F6A8-11CF-A442-00A0C90A8F39}'
    ies=DispatchEx(ShellWindowsCLSID)
    if len(ies)==0:
        return None
    for ie in ies:
        if ie.LocationURL==url:
            return ie
    return None

def NewIE(url):
    ie=DispatchEx("InternetExplorer.Application")
    ie.Navigate(url)
    return ie

def openIE(url):
    """
    >>> myie = ie.NewIE()
    """
    ie=ExistIE(url)
    if ie==None:
        ie=NewIE(url)
    return ie

def WaitIE(ie):
    while ie.Busy:
        time.sleep(1)

def Visible(ie):
    ie.Visible=1-ie.Visible

def GetBody(ie):
    WaitIE(ie)
    return ie.Document.body

def GetNodes(parentNode,tag):
    """
    >>> coldiv=GetNodes(body,"div")
    """
    childNodes=[]
    for childNode in parentNode.getElementsByTagName(tag):
        childNodes.append(childNode)
    return childNodes

def NodeByAttr(Nodes,nodeattr,nodeval):
    """
    >>> div_id_editor=NodeByAttr(coldiv,"id","editor_ifr")
    """
    for node in Nodes:
        if str(node.getAttribute(nodeattr))==nodeval:
            return node
    return None

def SetNode(node,val):
    node.innerHTML=val

if __name__=="__main__":
    url="about:blank"
    myie=NewIE(url)
    Visible(myie)
    mybody=GetBody(myie)
   
    SetNode(mybody,"<div>Genius</div>"*3)
    coldiv=GetNodes(mybody,"div")
    SetNode(coldiv[0],"<p>Hello</p>"*10)
    coldiv[0].SetAttribute("id","test")
    div_id_test=ie.NodeByAttr(coldiv,"id","test")
    div_p=GetNodes(div_id_test,"p")
    for div_per_p in div_p:
        print div_per_p.innerHTML

比如再去调用这个来登陆人人网：

# -*- coding:utf -*-
import getpass
import ie

url="http://renren.com/"

myie=ie.NewIE(url)
ie.Visible(myie)
mybody=ie.GetBody(myie)
input_ids=ie.GetNodes(mybody,"input")
input_id_email=ie.NodeByAttr(input_ids,"id","email")
input_id_email.value="yours@email.com"
input_id_psd=ie.NodeByAttr(input_ids,"id","password")
input_id_psd.value=getpass.getpass()
input_id_login=ie.NodeByAttr(input_ids,"id","login")
input_id_login.click()
