pythonxml.etree.ElementTree遍历xml所有节点XML文件内容：<students><studentname='刘备'sex='男'age='

python xml.etree.ElementTree遍历xml所有节点

XML文件内容：

<students> 
 <student name='刘备' sex='男' age='35'/> 
 <student name='吕布' sex='男' age='38'/> 
 <student name='貂蝉' sex='女' age='22'/> 
</students> 

代码：

#-*- coding: UTF-8 -*- 
# 从文件中读取数据 
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 
 for child in children_node: 
 walkData(child, level + 1, result_list) 
 return 
 
#获得原始数据 
#out: 
#[ 
# #ID, Level, Attr Map 
# [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 

输出结果：

[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'}]
