python - 导入错误 : No module named elementtree. SimpleXMLWriter

Question

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

但是显示错误:

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()

Python 2.5 及更高版本附带的 ElementTree 模块不包含 SimpleXMLWriter 模块；后者完全独立于 ElementTree 功能的其余部分。

为了生成 XML，我个人使用模板语言，例如 Chameleon .您还可以使用 ElementTree API 本身构建树，然后只需对结果调用 .write()。
