# -*- coding:utf-8 -*-
from xml.dom import minidom def get_attrvalue(node,attrname): return node.getAttribute(attrname) if node else ''

def get_nodevalue(node,index = 0): return node.childNodes[index].nodeValue def get_xmlnode(node,name): return node.getElementsByTagName(name) else [] def get_xml_data(filename = 'user.xml'): doc = minidom.parse(filename) root = doc.documentElement user_nodes = get_xmlnode(root,user') print "user_nodes:",user_nodes user_list=[] for node in user_nodes: user_id = get_attrvalue(node,0)">id') node_name = get_xmlnode(node,0)">username') node_email = get_xmlnode(node,0)">email') node_age = get_xmlnode(node,0)">age') node_sex = get_xmlnode(node,0)">sex') user_name =get_nodevalue(node_name[0]) user_email = get_nodevalue(node_email[0]) user_age = int(get_nodevalue(node_age[0])) user_sex = get_nodevalue(node_sex[0]) user = {} user['],user['] = ( int(user_id),user_name,user_email,user_age,user_sex ) user_list.append(user) return user_list def test_load_xml(): user_list = get_xml_data() for user in user_list : -----------------------------------------------------'
        if user: user_str=No.:\t%d\nname:\t%s\nsex:\t%s\nage:\t%s\nEmail:\t%s' % (int(user[']),0)">']) print user_str if __name__ == __main__": test_load_xml()
