# -*- coding: cp936 -*-
"""
使用minidom生成XML

"""
from xml.dom import minidom,Node

# 创建Document
doc = minidom.Document()
# 创建book节点
book = doc.createElement("book")
doc.appendChild(book)
# 创建Title节点
title = doc.createElement("title")
text = doc.createTextNode("Sample XML Thing")
title.appendChild(text)
book.appendChild(title)
# 创建author节点
author = doc.createElement("author")
# 创建name节点
name = doc.createElement("name")
first = doc.createElement("first")
first.appendChild(doc.createTextNode("Benjamin"))
name.appendChild(first)

last = doc.createElement("last")
last.appendChild(doc.createTextNode("Smith"))
name.appendChild(last)

author.appendChild(name)
book.appendChild(author)
# author节点完毕

# 创建chapter节点
chapter = doc.createElement("chapter")
chapter.setAttribute("number","1")
title = doc.createElement("title")
title.appendChild(doc.createTextNode("Fisrt Chapter"))
chapter.appendChild(title)

para = doc.createElement("para")
para.appendChild(doc.createTextNode("I think widgets are great.you should buy lots \
of them from"))
company = doc.createElement("company")
company.appendChild(doc.createTextNode("Springy widgets,Inc"))
para.appendChild(company)

chapter.appendChild(para)
# chapter节点完毕
book.appendChild(chapter)
# book节点完毕

print doc.toprettyxml(indent = " ")


2.生成的XML文件

<?xml version="1.0" ?>
<book>
    <title>
        Sample XML Thing
    </title>
    <author>
        <name>
            <first>
                Benjamin
            </first>
            <last>
                Smith
            </last>
        </name>
    </author>
    <chapter number="1">
        <title>
            Fisrt Chapter
        </title>
        <para>
            I think widgets are great.you should buy lots of them from
            <company>
                Springy widgets,Inc
            </company>
