pullparse解析基础（1）

一：assert中的xml文件

<?xml version="1.0" encoding="gbk"?>
<smartresult>
  <product type="mobile">
    <phonenum>13512345678</phonenum>
    <location>北京移动神州行卡</location>
    <phoneJx>有得有失，华而不实，须防劫财，始保平安 吉带凶</phoneJx>
  </product>
</smartresult>

二：domain中放入javabean数据

public class Product {
    private String type;
    private String phonenum;
    private String location;
    private String phoneJx;
    public String getType() {
        return type;
    }
    public void setType(String type) {
        this.type = type;
    }
    public String getPhonenum() {
        return phonenum;
    }
    public void setPhonenum(String phonenum) {
        this.phonenum = phonenum;
    }
    public String getLocation() {
        return location;
    }
    public void setLocation(String location) {
        this.location = location;
    }
    public String getPhoneJx() {
        return phoneJx;
    }
    public void setPhoneJx(String phoneJx) {
        this.phoneJx = phoneJx;
    }
    @Override
    public String toString() {
        return "Product [type=" + type + ", phonenum=" + phonenum
                + ", location=" + location + ", phoneJx=" + phoneJx + "]";
    }
    
}

三:解析

//拿到pull解析器
        XmlPullParser pullParser = Xml.newPullParser();
        try {
            //传入xml目标源文件
            //inputStream,需要一个流，第二个参数inputEncoding编码和xml文件中编码一致
            InputStream in = getAssets().open("result.xml");
            pullParser.setInput(in, "gbk");
            //拿到事件类型
            int eventType = pullParser.getEventType();
            //通过循环判断事件类型
            //pullParser.END_DOCUMENT:The static field XmlPullParser.END_DOCUMENT should be accessed in a static way
            Product p=null;
            while(eventType!=XmlPullParser.END_DOCUMENT){
                if(eventType==XmlPullParser.START_TAG){
                    //判断是否是元素的开始 , 只要是某个元素的开始位置, 那么就会进入这里 ,不考虑结束标签和结束文档
                    //获得 当前解析到的元素的名称
                    if("product".equals(pullParser.getName())){
                        //准备 product 类的一个实例 , 去 封装数据
                        p = new Product();
                        //获得第一个属性的值getAttributeValue();
                        //通过索引号的方式，索引从0 开始
                        String value = pullParser.getAttributeValue(0);
                        //设置给p的类型
                        p.setType(value);
                    }else if("phonenum".equals(pullParser.getName())){
                        // <phonenum>13512345678</phonenum>
                        //pullParser.nextText直接获得标签后的文本
                        String phonenum = pullParser.nextText();
                        p.setPhonenum(phonenum);
                    }else if("location".equals(pullParser.getName())){
                        String location = pullParser.nextText();
                        p.setLocation(location);
                    }else if("phoneJx".equals(pullParser.getName())){
                        String phoneJx = pullParser.nextText();
                        pullParser.getText();
                        p.setPhoneJx(phoneJx);
                    }
                }
                
                //手动移动“指针”
                eventType = pullParser.next();
                
            }
            
            if(p!=null){
                System.out.println(p.toString());
            }
            
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
