Question

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()

Python 2.5及更高版本附带的ElementTree模块不包含SimpleXMLWriter模块;后者与ElementTree功能的其余部分完全分开。

要生成XML，我个人使用Chameleon等模板语言。您还可以使用ElementTree API本身构建树，只需在结果上调用.write()。

我不是一个使用XML的向导，但是，看起来你需要安装elementtree（显然是SimpleXMLWriter wasn't included in python2.5 ......也许它从未被拉入标准库），或使用标准库中的设施。

对我来说，它看起来像是：

import xml.etree.ElementTree as ET
root = ET.Element('root')
#...

for colns in result:
     new_group = ET.SubElement(root,"Group")
     new_elem = ET.SubElement(new_group,"Name")
     new_elem.text = "%s" %(colns[0])
     #I suppose that:
     #ET.SubElement(new_group,"Name").text = str(colns[0])
     #would work too ...
     new_elem = ET.SubElement(new_group,"Mail")
     new_elem.text = "%s" %(colns[0])

然后，您可以使用root.write()。
