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'u5218u5907', 'sex': u'u7537'}] [3, 2, 'student', {'age': '38', 'name': u'u5415u5e03', 'sex': u'u7537'}] [4, 2, 'student', {'age': '22', 'name': u'u8c82u8749', 'sex': u'u5973'}]
