解析网络xml，并解决乱码问题

1.网络接口

private final static String SEARCH_LOCATION_ADDRESS = "http://www.yodao.com/smartresult-xml/search.s?type=mobile&q=";

?

2.查询

try{URL url = new URL(SEARCH_LOCATION_ADDRESS + userInput);//包装接口地址HttpURLConnection httpURLConnection = null;httpURLConnection = (HttpURLConnection)url.openConnection();httpURLConnection.setRequestMethod("POST");httpURLConnection.setDoOutput(true);//上传数据InputStream inputStream = httpURLConnection.getInputStream();//获取返回的数据流InputStreamReader isr = new InputStreamReader(inputStream, "gbk");//一定要在这个地方才不会乱码(utf-8,gb2312)BufferedReader br = new BufferedReader(isr);//利用BufferedReader将流转为StringString result = "";String temp;while((temp = br.readLine()) != null){result = result + temp;}String location = "";location = getStringFromXml(result);//将字符串传递过去，获取位置Toast toast = Toast.makeText(FindNumberActivity.this, location, Toast.LENGTH_LONG);toast.setGravity(Gravity.TOP, 0, 0);toast.show();System.out.println("查询执行完毕！");}catch (MalformedURLException e){e.printStackTrace();} catch (IOException e) {e.printStackTrace();} }

3.从xml中将需要的标签中的内容解析出来

/** * 将xml字符串解析出来，返回地点信息 * */public String getStringFromXml(String str) {String result = "";ByteArrayInputStream tInputStringStream = new ByteArrayInputStream(str.getBytes());XmlPullParser parser = Xml.newPullParser();try {    parser.setInput(tInputStringStream, "UTF-8");        int eventType = 0;    eventType = parser.getEventType();while (eventType != XmlPullParser.END_DOCUMENT) {switch (eventType) {case XmlPullParser.START_DOCUMENT:// 文档开始事件,可以进行数据初始化处理break;case XmlPullParser.START_TAG:// 开始元素事件String name = parser.getName();if (name.equals("location")) //匹配到location这个标签{result = parser.nextText().toString();//将标签中的内容读取出来，不是getText()!!!System.out.println("location解析出来啦：" + result);}break;case XmlPullParser.END_TAG:// 结束元素事件break;}eventType = parser.next();}} catch (XmlPullParserException e)  { e.printStackTrace(); } catch (IOException e)  { e.printStackTrace(); }return result;//将地址返回}
