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：

<"1.0" ?> <> <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。
