python写xml文件的操作实例

本文实例讲述了python写xml文件的操作的方法，分享给大家供大家参考。具体方法如下：

要生成的xml文件格式如下：

<?xml version="1.0" ?>
<!--Simple xml document__chapter 8-->
<book>
 <title>
   sample xml thing
 </title>
 <author>
   <name>
     <first>
       ma
     </first>
     <last>
       xiaoju
     </last>
   </name>
   <affiliation>
     Springs Widgets, Inc.
   </affiliation>
 </author>
 <chapter number="1">
   <title>
     First
   </title>
   <para>
     I think widgets are greate.You should buy lots of them forom
     <company>
       Spirngy Widgts, Inc
     </company>
   </para>
 </chapter>
</book>

Python实现代码如下：

from xml.dom import minidom, Node

doc = minidom.Document()

doc.appendChild(doc.createComment("Simple xml document__chapter 8"))

#generate the book
book = doc.createElement('book')
doc.appendChild(book)

#the title
title = doc.createElement('title')
title.appendChild(doc.createTextNode("sample xml thing"))
book.appendChild(title)

#the author section
author = doc.createElement("author")
book.appendChild(author)
name = doc.createElement('name')
author.appendChild(name)
firstname = doc.createElement('first')
firstname.appendChild(doc.createTextNode("ma"))
name.appendChild(firstname)
lastname = doc.createElement('last')
name.appendChild(lastname)
lastname.appendChild(doc.createTextNode("xiaoju"))

affiliation = doc.createElement("affiliation")
affiliation.appendChild(doc.createTextNode("Springs Widgets, Inc."))
author.appendChild(affiliation)

#The chapter
chapter = doc.createElement('chapter')
chapter.setAttribute('number', '1')
title = doc.createElement('title')
title.appendChild(doc.createTextNode("First"))
chapter.appendChild(title)
book.appendChild(chapter)

para = doc.createElement('para')
para.appendChild(doc.createTextNode("I think widgets are greate.\
You should buy lots of them forom"))
company = doc.createElement('company')
company.appendChild(doc.createTextNode("Spirngy Widgts, Inc"))
para.appendChild(company)
chapter.appendChild(para)

print doc.toprettyxml()
