Python使用ElementTree生成XML文件的完整示例

# *-* coding=utf-8
from xml.etree.ElementTree import ElementTree
from xml.etree.ElementTree import Element
from xml.etree.ElementTree import SubElement
from xml.etree.ElementTree import dump
from xml.etree.ElementTree import Comment
from xml.etree.ElementTree import tostring
import os
filename="book.xml"
def CreateXml():
  book =ElementTree()
  purOrder =Element("PurchaseOrder")
  book._setroot(purOrder)
  list = Element("account",{'idsn':'2390094'})
  purOrder.append(list)
  item = Element("item1",{"sku":"abcd","qty":"4"})
  SubElement(item,"Name").text="Potato Smasher"
  SubElement(item,"Description").text="Smash Potatoes like never before"
  purOrder.append(item)
  item = Element("item2",{"sku":"gfhi","qty":"40"})
  SubElement(item,"Name").text="Beijing"
  SubElement(item,"Description").text="My Country"
  purOrder.append(item)
  indent(purOrder)
  return book
def indent(elem,level=0):
  i ="\n"+level*"  "
  print elem;
  if len(elem):
    if not elem.text or not elem.text.strip():
      elem.text = i + "  "
    for e in elem:
      print e
      indent(e,level+1)
    if not e.tail or not e.tail.strip():
      e.tail =i
  if level and (not elem.tail or not elem.tail.strip()):
    elem.tail =i
  return elem
if __name__ == '__main__':
  book =CreateXml()
  book.write(filename,"utf-8")
  #book.write("book2.xml","utf-8",True) #true is with xml declaration
