Python xml.etree.ElementTree traversal of all XML nodes

XML file Contents:

<students> 
  <student name= ' Liu Bei ' sex= ' man ' age= '/> <student ' lv bu ' name= ' sex= ' 
  man ' 
  <student name= ' Diao Chan ' sex= ' female ' age= '/> 
</students> 

Code:

#-*-coding:utf-8-*-  
# Read data from File 
import xml.etree.ElementTree as ET 
 
#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 to Child in 
  Children_node: 
    Walkdata (Child, Level + 1, result_list) 
  return 
 
#获得原始数据 
#out: 
#[ 
#  #ID, level, Attr map< c23/>#  [1, 1, {' id ': 1, ' name ': ' Test1 '}], 
#  [2, 1, {' id ': 1, ' name ': ' Test2 '}], 
#] 
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__ ': 
  file_name = ' Test.xml ' 
  R = Getxmldata (file_name) for 
  x in R: 
    print x 
  Pass 

Output results:

[1, 1, ' Students ', {}] 
[2, 2, ' student ', {' age ': '], ' name ': U ' \u5218\u5907 ', ' Sex ': U ' \u7537 '}] 
[3, 2, ' student ', {' age ': '], ' name ': U ' \u5415\u5e03 ', ' Sex ': U ' \u7537 '}] 
[4, 2, ' student ', {' age ': ' n ', ' name ': U ' \u8c82\u8749 ', ' Sex ': U ' \u5973 '}]
