android中xml的pull解析

xml的pull解析：

   //類加載器加載xml文件

InputStream is = MainActivity.class.getClassLoader().getResourceAsStream("weather.xml");

    //生成xml的pull解析器

    XmlPullParser pull = Xml.newPullParser();

    try {

    //設置輸入流

pull.setInput(is, "utf-8");

        //解析器當前處于的狀態

int type = pull.getEventType();

Weather weather = null ;

while (type != XmlPullParser.END_DOCUMENT) {

switch (type) {

            //當前是開始標簽的節點

    case XmlPullParser.START_TAG:

                //拿到節點標簽的名字

        String name = pull.getName();

            //判斷節點標簽的名字 （下面同這兒），然后放到weather對象中  

        if("channel".equals(name)){

            weather = new Weather();

            weather.setId(pull.getAttributeValue(0));

        }

        if("city".equals(name)){

            weather.setName(pull.nextText());

        }

        if("temp".equals(name)){

            weather.setTemp(pull.nextText());

        }

        if("wind".equals(name)){

            weather.setWind(pull.nextText());

        }

        break;

        //如果是結束標簽的節點，此處將weather對象放入list集合保存

case XmlPullParser.END_TAG:

    String tagname = pull.getName();

    if("channel".equals(tagname)){

        list.add(weather);

    }

default:

    break;

        }

//此處必須寫，否則不會向下執行

        type = pull.next();

        }

    } catch (Exception e) {

e.printStackTrace();

    }

}
