删除xml节点.py

from lxml import etree
import os

# 删除指定文件夹下xml文件中节点（存在多个重复节点删除，需要执行多次）

def createFile(oripath):
    xml_list = os.listdir("./11")
    for i in xml_list:  # 遍历所有xml文件
        fullPath = oripath + i  # 完整路径

        remove_(fullPath)  # 将完整路径作为参数传入调用该函数
def remove_(path):  # path 是原来xml文件的完整路径
    tree = etree.parse(path)
    for i in tree.iter():  # i是该xml中的所有标签
        if i.tag == "object":  # 找到为object的tag
            if i.find("name").text == "cuobiao":
                parent = i.getparent()
                print(i)
                parent.remove(i)
    tree.write(path, encoding='utf-8')  # 将tree写入新的文件
