Python解析xml中dom元素的方法

from xml.dom import minidom
try:
    xmlfile = open("path.xml", "a+")
    #xmldoc = minidom.parse( sys.argv[1])
    xmldoc = minidom.parse(xmlfile)
except :
    #updatelogger.error( "Can't parse Xml File." )
    sys.exit(0)
 
ClientOutputPath = xmldoc.getElementsByTagName('D')[0].attributes['path'].value
OutputPath = xmldoc.getElementsByTagName('h')[0].attributes['path'].value
BasePath = xmldoc.getElementsByTagName('th')[0].attributes['path'].value
ToolPath = xmldoc.getElementsByTagName('ub')[0].attributes['path'].value
ToolPath_2 = xmldoc.getElementsByTagName('ub')[1].attributes['path'].value
 
ClientOutputPath.replace( "\\", "\\\\" )
OutputPath.replace( "\\", "\\\\" )
BasePath.replace( "\\", "\\\\" )
ToolPath.replace( "\\", "\\\\" )
 
print ClientOutputPath
print OutputPath
print BasePath
print ToolPath
print ToolPath_2
