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

def getXmlData(file_name):
  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 

if __name__ == '__main__':
    #'d:\\fenlei2.xml'
    file_name = 'd:\\222.xml'
    R = getXmlData(file_name)
    for x in R:
        print(x)
        pass
