ImportError：No module named elementtree.SimpleXMLWriter

在我的python代碼中，我試圖以XML格式顯示輸出。爲此，我使用了XMLwriter。ImportError：No module named elementtree.SimpleXMLWriter

但它顯示錯誤：

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

這會導致錯誤的代碼行是：

from elementtree.SimpleXMLWriter import XMLWriter

我的整個Python代碼是：

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()

你需要安裝[elementtree工具包]（http://effbot.org/zone/xml-writer.htm）我估計。 – tuxuday

是在您的環境中安裝的''elementtree''模塊？ –

你正在使用哪個版本的python？此錯誤表明您沒有安裝元件樹。這是哪個操作系統？ – Oz123

我不是嚮導與XML，但是，它看起來像你要麼安裝elementtree（顯然SimpleXMLWriter wasn't included in python2.5 ...也許它從未被拉入標準庫），或使用標準庫中的設施。

對我來說，它看起來像這樣的：

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])

然後，您可以使用root.write()寫這個。
