Python创建xml文件示例

本文实例讲述了Python创建xml文件的方法。分享给大家供大家参考，具体如下：

这是一个使用ElementTree有关类库，生成xml文件的例子

# *-* 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
