从Python中的多个文件返回XML值？

Question

因此，我正在使用Python编写的基于浏览器的程序，该程序解析目录中多个文件中的XML数据，然后返回页面上某些XML标记的值。我已经成功地能够从其中一个XML文件返回值，但是希望从目录中的每个文件收集数据并以电子表格格式返回值。如何解析每个XML文件中的数据？另外，XML文件不是静态的，会有新文件来去。谢谢！下面是我的代码：

from xml.dom.minidom import parseString

import os
path = 'C:\Vestigo\XML'
listing = os.listdir(path)
for infile in listing:
    print infile

file = open(os.path.join(path,infile),'r')

data = file.read()
file.close()

dom = parseString(data)

xmlTag0 = dom.getElementsByTagName('Extrinsic')[0].toxml()
xmlData0 = xmlTag0.replace('<Extrinsic>','').replace('</Extrinsic>','')
xmlTag1 = dom.getElementsByTagName('DeliverTo')[0].toxml()
xmlData1 = xmlTag1.replace('<DeliverTo>','').replace('</DeliverTo>','')
xmlTag2 = dom.getElementsByTagName('Street1')[0].toxml()
xmlData2 = xmlTag2.replace('<Street1>','').replace('</Street1>','')
xmlTag3 = dom.getElementsByTagName('City')[0].toxml()
xmlData3 = xmlTag3.replace('<City>','').replace('</City>','')
xmlTag4 = dom.getElementsByTagName('State')[0].toxml()
xmlData4 = xmlTag4.replace('<State>','').replace('</State>','')
xmlTag5 = dom.getElementsByTagName('PostalCode')[0].toxml()
xmlData5 = xmlTag5.replace('<PostalCode>','').replace('</PostalCode>','')


import cherrypy
class Root(object):
    def index(self):
        return ('Order Number:', ' ', xmlData0, '<br>Name: ', xmlData1, '<br>Street   Address: ', xmlData2, '<br>City/State/Zip: ', xmlData3, ', ', xmlData4, ' ', xmlData5, ' ', """<br><br><a href="/exit">Quit</a>""")
    index.exposed = True

    def exit(self):
        raise SystemExit(0)
    exit.exposed = True

def start():
    import webbrowser
    cherrypy.tree.mount(Root(), '/')
    cherrypy.engine.start_with_callback(
        webbrowser.open,
        ('http://localhost:8080/',),
        )
    cherrypy.engine.block()

if __name__=='__main__':
    start()

为了从目录中的每个文件中提取数据，我在下面使用了以下代码：

from xml.dom.minidom import parse, parseString
import os, glob, re
import cherrypy
class Root(object):
    def index(self):
        path = 'C:\Vestigo\XML'

        TOTALXML = len(glob.glob(os.path.join(path, '*.xml')))
        print TOTALXML
        i = 0

        for XMLFile in glob.glob(os.path.join(path, '*.xml')):
            xmldoc = parse(XMLFile)
            order_number = xmldoc.getElementsByTagName('Extrinsic')[0].firstChild.data
            order_name = xmldoc.getElementsByTagName('DeliverTo')[0].firstChild.data
            street1 = xmldoc.getElementsByTagName('Street1')[0].firstChild.data
            state = xmldoc.getElementsByTagName('State')[0].firstChild.data
            zip_code = xmldoc.getElementsByTagName('PostalCode')[0].firstChild.data
            OUTPUTi = order_number+' '+order_name+' '+street1+' '+state+' '+zip_code
            i += 1
            print OUTPUTi
        return (OUTPUTi, """<br><br><a href="/exit">Quit</a>""")
    index.exposed = True

    def exit(self):
        raise SystemExit(0)
    exit.exposed = True

def start():
    import webbrowser
    cherrypy.tree.mount(Root(), '/')
    cherrypy.engine.start_with_callback(
        webbrowser.open,
        ('http://localhost:8080/',),
        )
    cherrypy.engine.block()

if __name__=='__main__':
    start()
