python minidom不关闭<xml tag>

Question

我正在使用minidom遇到一种奇怪的行为.我运行以下代码:

import os
import sys
from xml.dom import minidom
def generateReleaseXMLFile():
    modelPath = "%./model/"
    # Create the parser
    xsydoc  = minidom.Document()
    # Create the element ScriptModelVersion
    scriptModelVersion  = xsydoc.createElement('ScriptModelVersion')
    # Assign all the attributes
    scriptModelVersion.setAttribute("Major", "1")
    scriptModelVersion.setAttribute("Minor", "2")
    scriptModelVersion.setAttribute("Patch", "3")
    scriptModelVersion.setAttribute("ReseaseDate", "2011-05-20")
    # Append the root to the document
    xsydoc.appendChild(scriptModelVersion)
    # Create the file descriptor
    fdesc = open(modelPath+"Release.xml", "w")
    # Write the file
    fdesc.write(xsydoc.toprettyxml())
    # Close the file
    fdesc.close()
    print xsydoc.toprettyxml()

generateReleaseXMLFile()

它生成以下输出:

<?xml version="1.0" ?>
<ScriptModelVersion Major="9" Minor="0" Patch="1" ReleaseDate="2011-05-20"/>

没有xml标签关闭.我真的不知道为什么它会保持文档打开.有没有人遇到过同样的问题？或者我只是忘记了一些非常明显的想法,我只是简单地看到了问题？

该<?xml ... ?>不是一个标签,但XML声明.没有必要关闭它,你的文件是完美的形状.
