python xml.etree.ElementTree遍歷xml所有節點

XML文件內容：

<students>   <student name='劉備' sex='男' age='35'/>   <student name='呂布' sex='男' age='38'/>   <student name='貂蟬' sex='女' age='22'/> </students> 

代碼：

#-*- coding: UTF-8 -*-  # 從文件中讀取數據 import xml.etree.ElementTree as ET  #全局唯一標識 unique_id = 1  #遍歷所有的節點 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      #遍歷每個子節點   children_node = root_node.getchildren()   if len(children_node) == 0:     return   for child in children_node:     walkData(child, level + 1, result_list)   return  #獲得原始數據 #out: #[ #  #ID, Level, Attr Map #  [1, 1, {'ID':1, 'Name':'test1'}], #  [2, 1, {'ID':1, 'Name':'test2'}], #] def getXmlData(file_name):   level = 1 #節點的深度從1開始   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 

輸出結果：

[1, 1, 'students', {}] [2, 2, 'student', {'age': '35', 'name': u'/u5218/u5907', 'sex': u'/u7537'}] [3, 2, 'student', {'age': '38', 'name': u'/u5415/u5e03', 'sex': u'/u7537'}] [4, 2, 'student', {'age': '22', 'name': u'/u8c82/u8749', 'sex': u'/u5973'}]
