Python使用MYSQLDB实现从数据库中导出XML文件的方法

# -*- coding: utf-8 -*-
from xml.dom import minidom
import MySQLdb
conn = MySQLdb.connect(host='localhost',user='root',passwd='xxx',db='my_xml',charset="utf8")
cursor = conn.cursor()
cursor.execute('select id, name, style, description, family from ppy_fish')
res_list = cursor.fetchall()
print len(res_list)
doc = minidom.Document()
root = doc.createElement("data")
doc.appendChild(root)
ATTRIBUTE = {"n":1, "d":3}
for res in res_list:
  node = doc.createElement(res[2])
  for i in ATTRIBUTE:
    id_node = doc.createElement("%s" % i)
    data = doc.createTextNode("%s" % res[ATTRIBUTE[i]])
    id_node.appendChild(data)
    node.appendChild(id_node)
  root.appendChild(node)
str_xml = doc.toxml("utf-8")
f = open('fish.xml', 'w')
f.write(str_xml)
f.close()
cursor.close()
conn.close()
