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：
<?xmlversion="1.0"?> <!--Simplexmldocument__chapter8--> <book> <title> samplexmlthing </title> <author> <name> <first> ma </first> <last> xiaoju </last> </name> <affiliation> SpringsWidgets,Inc. </affiliation> </author> <chapternumber="1"> <title> First </title> <para> Ithinkwidgetsaregreate.Youshouldbuylotsofthemforom <company> SpirngyWidgts,Inc </company> </para> </chapter> </book>
Python实现代码如下：
fromxml.domimportminidom,Node
doc=minidom.Document()
doc.appendChild(doc.createComment("Simplexmldocument__chapter8"))
#generatethebook
book=doc.createElement('book')
doc.appendChild(book)
#thetitle
title=doc.createElement('title')
title.appendChild(doc.createTextNode("samplexmlthing"))
book.appendChild(title)
#theauthorsection
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("SpringsWidgets,Inc."))
author.appendChild(affiliation)
#Thechapter
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("Ithinkwidgetsaregreate.\
Youshouldbuylotsofthemforom"))
company=doc.createElement('company')
company.appendChild(doc.createTextNode("SpirngyWidgts,Inc"))
para.appendChild(company)
chapter.appendChild(para)
printdoc.toprettyxml()
