python xml练习：从database.xml文件取databaselist的ip、name、passwd，写入列表

xml：

<?xml version='1.1' encoding='utf-8'?>
<!--this is a test about xml-->
<databaselist type='oracle'>
    <database userArea='suzhou'>
        <ip>10.192.128.88</ip>
        <name>'xiasam'</name>
        <passwd>!QAZ2wsx</passwd>
    </database>
    <database userArea='BeiJing'>
        <ip>10.192.128.89</ip>
        <name>'wu li'</name>
        <passwd>3edc$RFV</passwd>
    </database>
</databaselist>

#coding=utf-8

def getInfo(xml_file):
    from xml.dom.minidom import parse
    DOMTree=parse(xml_file)
    databaselist=DOMTree.documentElement
    #print databaselist
    result=[]
    databaselists=databaselist.getElementsByTagName('database')
    for i in databaselists:#
        for j in i.childNodes[1:6:2]:
            print j.tagName,j.childNodes[0].data
            result.append("%s : %s"%(j.tagName,j.childNodes[0].data))
    return result

print getInfo(r"d:\\database_test.xml")

c:\Python27\Scripts>python task_test.py
ip 10.192.128.88
name 'xiasam'
passwd !QAZ2wsx
ip 10.192.128.89
name 'wu li'
passwd 3edc$RFV
[u'ip : 10.192.128.88', u"name : 'xiasam'", u'passwd : !QAZ2wsx', u'ip : 10.192.128.89', u"name : 'wu li'", u'passwd : 3edc$RFV']

下边是调试代码（注释）

#coding=utf-8

def getInfo(xml_file):
    from xml.dom.minidom import parse
    DOMTree=parse(xml_file)
    databaselist=DOMTree.documentElement
    #print databaselist
    result=[]
    databaselists=databaselist.getElementsByTagName('database')
    for i in databaselists:
        print "i:",i
        for j in i.childNodes[1:6:2]:
            print "j:",j
            print "j.tagName:",j.tagName,"j.childNodes[0].data:",j.childNodes[0].data
            result.append("%s : %s"%(j.tagName,j.childNodes[0].data))
    return result

print getInfo(r"d:\\database_test.xml")
