python写xml文件的操作实例

本文实例讲述了python/' target='_blank'>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()
