Android(安卓)解析XML 之pull

Pull解析器主要的事件和方法 XmlPullParser parser = Xml.newPullParser(); //获得pull解析器 parser.setInput(fileInputStream, “utf-8”); //把xml文档以流的形式传给解析器 int eventCode = parser.getEventType(); //获得解析事件返回的code XmlPullParser.START_DOCUMENT //开始文档 XmlPullParser.END_DOCUMENT //结束文档 XmlPullParser.START_TAG //开始节点 XmlPullParser.END_TAG //结束节点 eventCode = parser.next(); //解析下一个节点parser.getName() //获得节点名称 parser.getAttributeValue(null, “id”)//获得节点属性 parser.nextText()//获得test文本值

在assets下面新建一个student.xml

<?xml version="1.0" encoding="utf-8"?>  <stundets>  <student id="2009081315">    <name>饶伟</name>    <speciality>计算机科学与技术</speciality>    <qq>812200157</qq>  </student>    <student id="2009081316">    <name>小伟</name>    <speciality>网络工程</speciality>    <qq>812200156</qq>  </student>    <student id="2009081318">    <name>伟哥</name>    <speciality>软件工程</speciality>    <qq>812200158</qq>  </student></stundets>
