python – ImportError：没有名为elementtree.SimpleXMLWriter的模块

在我的python代码中,我试图以XML格式显示输出.为此我使用XMLwriter.

但它显示错误：

Traceback (most recent call last):
  File "C:\Users\Ponmani\Desktop\test.cgi", line 8, in <module>
    from elementtree.SimpleXMLWriter import XMLWriter
ImportError: No module named elementtree.SimpleXMLWriter

导致错误的行是：

from elementtree.SimpleXMLWriter import XMLWriter

我的整个python代码是：

import os
import cgi
import MySQLdb
import cgitb
from xml.etree.ElementTree import ElementTree
from elementtree.SimpleXMLWriter import XMLWriter
import sys
import SecureDb
cgitb.enable()
print "Content-type: text/xml\n\n";
root=xml.start("root")
conn= MySQLdb.connect(host = SecureDb.host ,user =SecureDb.user ,passwd=SecureDb.password ,db=SecureDb.database)
cursor=conn.cursor()
xml=XMLWriter(sys.stdout)
cursor.execute("select * from register where Name='Subburaj'")
result=cursor.fetchall()
if(result!=()):    
    for colns in result:
         xml.start("Group")
         xml.element("Name","%s" %(colns[0]))
         xml.element("Mail","%s" %(colns[1]))
print result
xml.end()
xml.close(root)
conn.commit()
cursor.close()
conn.close()

解决方法:

Python 2.5及更高版本附带的ElementTree模块不包含SimpleXMLWriter模块;后者与ElementTree的其他功能完全分开.

为了生成XML,我个人使用模板化语言,如Chameleon.您还可以使用ElementTree API本身构建树,只需在结果上调用.write().
