Question

import MySQLdb
from xml.dom import minidom
import xml.dom.minidom

xmldoc = xml.dom.minidom.parse("Country.xml")

country= xmldoc.getElementsByTagName("country")[0]

sensors = country.getElementsByTagName("sensor")

for sensor in sensors:
    Translation = sensor.getElementsByTagName("Translation")[0].firstChild.data
    Name = sensor.getElementsByTagName("Name")[0].firstChild.data
    Prefix = sensor.getElementsByTagName("Prefix")[0].firstChild.data
    Percentage = sensor.getElementsByTagName("Percentage")[0].firstChild.data
    Position = sensor.getElementsByTagName("Position")[0].firstChild.data

    db = MySQLdb.connect("localhost","root","akshay","country")

# prepare a cursor object using cursor() method
cursor = db.cursor()

# Drop table if it already exist using execute() method.
cursor.execute("DROP TABLE IF EXISTS country_table")

# Create table as per requirement
sql = """CREATE TABLE country_table (_
         Translation  VARCHAR(20) NOT NULL,
         Name  VARCHAR(20) NOT NULL,
         Prefix INT(5) NOT NULL,  
         Percentage INT(3) NOT NULL,
         Position INT(3) NOT NULL
          )"""

sql1= ("INSERT INTO country_table(Translation, Name, Prefix, Percentage,Position) VALUES(%s, %s, %s, %s,%s)"
   %(Translation, Name, Prefix, Percentage,Position))

try:
   # Execute the SQL command

     cursor.execute(sql1)

except:
   # Rollback in case there is any error
   db.rollback()

# disconnect from server
db.close()

我收到以下错误：

Traceback（最近一次调用最后一次）：文件“test.py”，第5行，in xmldoc = xml.dom.minidom.parse（“Country.xml”）File“/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/xml/dom/minidom.py”， 1918年，在解析 return expatbuilder.parse（file）File“/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/xml/dom/expatbuilder.py”，第924行，解析 result = builder.parseFile（fp）File“/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/xml/dom/expatbuilder.py”，第211行，在parseFile中 parser.Parse（“”，True）xml.parsers.expat.ExpatError：找不到元素：第43行，第0列

请帮忙。
