xml解析（一） XmlPullParser的使用

XmlPullParser是android自带的xml解析器

public static ArrayList<TvUrl> getChannelsData(InputStream is) {ArrayList<TvUrl> list = null;TvUrl tvurl = null;XmlPullParserFactory pullFactory;try {pullFactory = XmlPullParserFactory.newInstance();XmlPullParser xmlPullParser = pullFactory.newPullParser();if(is == null){return null;}xmlPullParser.setInput(is, "UTF-8");int eventType = xmlPullParser.getEventType();while (eventType != XmlPullParser.END_DOCUMENT) {String tagName = xmlPullParser.getName();switch (eventType) {case XmlPullParser.START_DOCUMENT:list =  new ArrayList<TvUrl>();break;case XmlPullParser.START_TAG:if("tv".equals(tagName)){tvurl = new TvUrl();}else if ("channelid".equals(tagName)) {tvurl.setid(xmlPullParser.nextText());//Log.i(tvurl.getid());}else if("name".equals(tagName)){tvurl.setName(xmlPullParser.nextText());//Log.i(tvurl.getName());}else if("url".equals(tagName)){String str = xmlPullParser.nextText();tvurl.AddUrl(str);//Log.i(str);}break;case XmlPullParser.END_TAG:if ("tv".equals(tagName) && tvurl != null) {list.add(tvurl);}break;default:break;}eventType = xmlPullParser.next();}} catch (XmlPullParserException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}return list;}

xmlPullParser.nextText() 是解析xml某个标签的值。

xmlPullParser.getAttributeValue(0) 是解析xml某个标签下中属性值，0代表位置为0的属性
