test.xml

<?xml version="1.0" encoding="UTF-8"?>
<Site>
    <WebSites>
        <website>http://www.xxx.net</website>
        <loginurl>http:///www.xxx.net/login.php</loginurl>
        <username>uname=xxx</username>
        <passwd>pass=123456</passwd>
        <other><![CDATA[r=5&remember=0&ur=xxx]]></other>
        <config>WebSite.ini</config>
        <configname>XXX</configname>
    </WebSites>
        <WebSites>
        <website>http://www.xxx.com</website>
        <loginurl>http:///www.xxx.com/login.php</loginurl>
        <username>uname=xxx</username>

        <config>WebSite.ini</config>
        <configname>XXX</configname>

</Site>

结果：

[[(u'website', u'http://www.xxx.net'), (u'loginurl', u'http:///www.xxx.net/login.php'), (u'username', u'uname=xxx'), (u'passwd', u'pass=123456'), (u'other', u'r=5&remember=0&ur=xxx'), (u'config', u'WebSite.ini'), (u'configname', u'XXX')], [(u'website', u'http://www.xxx.com'), (u'loginurl', u'http:///www.xxx.com/login.php'), (u'username', u'uname=xxx'), (u'passwd', u'pass=123456'), (u'other', u'r=5&remember=0&ur=xxx'), (u'config', u'WebSite.ini'), (u'configname', u'XXX')]]
