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>
<passwd>pass=123456</passwd>
<other><![CDATA[r=5&remember=0&ur=xxx]]></other>
<config>WebSite.ini</config>
<configname>XXX</configname>
</WebSites>
</Site>

結果：

m@m-desktop:~/.wkl/a$ python test.py 
[[(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')]]
