本篇章节讲解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()

希望本文所述对大家的Python程序设计有所帮助。
