Android使用XmlPullParser解析xml数据

<?xml version="1.0" encoding="utf-8"?>
<one>
<title type="text">lallalalallala</title>
    <two>
    <title type="text">Where is my data file?</title>
    <link rel="alternate" href="http:www.xx.com" />
    <summary type="html">
        dodododoodoododo

    </summary>
    </two>

</one>
