把文件名与XML的filename

只需要更改"path"即可!
所有的XML文件都在Annotations文件夹下面

import os
import os.path
import xml.dom.minidom
path = r'/home/yuan3080/桌面/detection_paper_6/mmdetection-master1/mmdetection-master/VOCdevkit/VOC2007/Annotations'
files = os.listdir(path)  # 得到文件夹下所有文件名称
s = []
count = 0
for xmlFile in files:  # 遍历文件夹
    if not os.path.isdir(xmlFile):  # 判断是否是文件夹,不是文件夹才打开
            name1 = xmlFile.split('.')[0]
            dom = xml.dom.minidom.parse(path + '/' + xmlFile)
            root = dom.documentElement
            newfolder = root.getElementsByTagName('folder')
            newpath = root.getElementsByTagName('path')
            newfilename = root.getElementsByTagName('filename')
         #   newfolder[0].firstChild.data = 'VOCdevkit\VOC2012\JPEGImages'
     #       newpath[0].firstChild.data = 'VOCdevkit\VOC2012\JPEGImages' + '\\' + name1 + '.jpg'
            newfilename[0].firstChild.data = name1 + '.jpg'
            with open(os.path.join(path, xmlFile), 'w') as fh:
                dom.writexml(fh)
                print('写入成功')
            count = count + 1
