python 遍历xml所有节点

1.xml文件

2.代码

#coding:utf-8

import xml

import xml.etree.ElementTree as ET

"""

实现从xml文件中读取数据

"""

#全局唯一标识

unique_id = 1

#遍历所有的节点

def walkData(root_node, level, result_list):

  global unique_id

  temp_list =[unique_id, level, root_node.tag, root_node.attrib]

  result_list.append(temp_list)

  unique_id += 1

  #遍历每个子节点

  children_node = root_node.getchildren()

  if len(children_node) == 0:

    return

  for child in children_node:

    walkData(child, level + 1, result_list)

  return

  level = 1 #节点的深度从1开始

  result_list = []

  root = ET.parse(file_name).getroot()

  walkData(root, level, result_list)

  return result_list

    R = getXmlData(file_name)

    for x in R:

        print(x)
