用Python创建XML(转)

在官方网站没有找到多少有用的知识。结果在Python and XML: An Introduction找到了一篇教程，抽空对照做，然后再总结分享出来。先来一个简单的：

 from xml.dom.minidom import Document

 # Create the minidom document
 doc = Document()

 # Create the <wml> base element
 wml = doc.createElement("wml")
 doc.appendChild(wml)

 # Create the main <card> element
 maincard = doc.createElement("card")
 maincard.setAttribute("id", "main")
 wml.appendChild(maincard)

 # Create a <p> element
 paragraph1 = doc.createElement("p")
 maincard.appendChild(paragraph1)

 # Give the <p> elemenet some text
 ptext = doc.createTextNode("This is a test!")
 paragraph1.appendChild(ptext)

 # Print our newly created XML
 print doc.toprettyxml(indent="  ")

运行的结果为：

 <?xml version="1.0" ?>
 <wml>
 <card id="main">
 <p>
 This is a test!
 </p>
 </card>
 </wml>
