Python 使用ElementTree 删除/修改 xml文件内容

import os, sys
import glob
from xml.etree import ElementTree as ET
#批量读取Annotations下的xml文件
xml_dir=r'E:\TUNNEL\data2\Annotations'
xml_list= glob.glob(xml_dir + '/*.xml')
i = 0
for xml in xml_list:
    print(xml)
    per=ET.parse(xml)
    root = per.getroot()
    p=per.findall('/object')
    i += 1
    for oneper in p:  #遍历p
        child=oneper.getchildren()[0] #找出person节点的子节点 name
        if child.text=='conic':
            root.remove(oneper)  #删除此节点
            print(xml,child.text,'has been deleted')
        if child.text == 'toss':
            root.remove(oneper)  #删除此节点
            print(xml,child.text,'has been deleted')
        if child.text == 'minibus':
            child.text = 'car'  #修改节点名字
            print(xml,'mini_bus','has been renamed','car')          
    per.write(xml)
    print(child.tag,':',child.text) 
print(i,'files have been mended')
