XMLpull解析使用

pull解析是安卓自带的解析方式

具体使用直接看代码

private List<NewsBody> xmlParser(InputStream  inputStream) {
        try {
            XmlPullParserFactory factory= XmlPullParserFactory.newInstance();
            //获取XmlPullParser实例
            XmlPullParser pullParser=factory.newPullParser();
            pullParser.setInput(inputStream, "UTF-8");
            //开始
            int eventType=pullParser.getEventType();

            while(eventType!=XmlPullParser.END_DOCUMENT){
                String nodeName=pullParser.getName();
                switch (eventType) {
                    //文档开始
                    case XmlPullParser.START_DOCUMENT:
                        bodies=new ArrayList<NewsBody>();
                        break;
                    //开始节点
                    case XmlPullParser.START_TAG:
                        if("item".equals(nodeName)){
                            body=new NewsBody();
                        }else if("title".equals(nodeName)){
                            body.setTitle(pullParser.nextText());
                        }else if("copyright".equals(nodeName)){
                            body.setCopyright(pullParser.nextText());
                        }else if("pubDate".equals(nodeName)){
                            body.setPubDate(pullParser.nextText());
                        }else if("link".equals(nodeName)){
                            body.setlink(pullParser.nextText());
                        }
                        break;
                    //结束节点
                    case XmlPullParser.END_TAG:
                        if("item".equals(nodeName)){
                            bodies.add(body);
                           // body=null;
                        }
                        break;
                    default:
                        break;
                }
                // 手动的触发下一个事件
                eventType=pullParser.next();
            }
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return bodies;
    }
