android使用xmlpull方式解析xml示例

需要解析的xml内容：

<app><dynamic><uploadPhoto>true</uploadPhoto><!-- 是否支持上传图片  false代表不支持，true代表支持 --><specifyFriends>true</specifyFriends><!-- 是否支持@好友  false代表不支持，true代表支持  --><sharWx>true</sharWx><!--  是否支持分享到微信  false代表不支持，true代表支持  --><emoji>true</emoji><!--  是否支持表情  false代表不支持，true代表支持  --><score>true</score><!--  是否支持积分  false代表不支持，true代表支持  --></dynamic><doubt><photo>true</photo><!-- 是否支持图片   false代表不支持，true代表支持 --><supplementaryQuestion>true</supplementaryQuestion><!-- 是否支持问题补充   false代表不支持，true代表支持  --><collect>true</collect><!--  是否支持收藏   false代表不支持，true代表支持  --></doubt><courses><elective>true</elective><!-- 是否有选修课 false代表没有，true代表允许 --></courses></app>

http封装类：

package com.tudou.activity.work3;import java.io.IOException;import java.io.InputStream;import java.net.HttpURLConnection;import java.net.URL;import android.util.Log;public class HttpUtil {public static InputStream getInputStream(String path) {try {URL url = new URL(path);HttpURLConnection conn = (HttpURLConnection) url.openConnection();conn.setDoInput(true);conn.setReadTimeout(3000);conn.setConnectTimeout(3000);conn.setRequestMethod("POST");if (conn.getResponseCode() == 200) {Log.d("mylog", "getResponseCode:" + 200);return conn.getInputStream();}} catch (IOException e) {e.printStackTrace();}return null;}}

使用xmlpull解析xml，直接用json封装：

package com.tudou.activity.work3;import java.io.IOException;import java.io.InputStream;import java.util.List;import org.json.JSONException;import org.json.JSONObject;import org.xmlpull.v1.XmlPullParser;import org.xmlpull.v1.XmlPullParserException;import org.xmlpull.v1.XmlPullParserFactory;import android.util.Log;public class XmlParser {public static String getXML(InputStream inputStream, String inputEncoding) {JSONObject obj = new JSONObject();try {// Log.d("mylog", "XmlParser" + 200);XmlPullParser parser = XmlPullParserFactory.newInstance().newPullParser();parser.setInput(inputStream, inputEncoding);int eventType = parser.getEventType();JSONObject obj2 = new JSONObject();JSONObject obj3 = new JSONObject();JSONObject obj4 = new JSONObject();while (eventType != XmlPullParser.END_DOCUMENT) {// Log.d("mylog", "eventType:" + eventType);switch (eventType) {case XmlPullParser.START_DOCUMENT:break;case XmlPullParser.START_TAG:Log.d("mylog", "name:" + parser.getName());if ("uploadPhoto".equals(parser.getName())) {obj2.put(parser.getName(), parser.nextText());} else if ("specifyFriends".equals(parser.getName())) {obj2.put(parser.getName(), parser.nextText());} else if ("sharWx".equals(parser.getName())) {obj2.put(parser.getName(), parser.nextText());} else if ("emoji".equals(parser.getName())) {obj2.put(parser.getName(), parser.nextText());} else if ("score".equals(parser.getName())) {obj2.put(parser.getName(), parser.nextText());} else if ("photo".equals(parser.getName())) {obj3.put(parser.getName(), parser.nextText());} else if ("supplementaryQuestion".equals(parser.getName())) {obj3.put(parser.getName(), parser.nextText());} else if ("collect".equals(parser.getName())) {obj3.put(parser.getName(), parser.nextText());} else if ("elective".equals(parser.getName())) {obj4.put(parser.getName(), parser.nextText());}break;case XmlPullParser.END_TAG:if ("app".equals(parser.getName())) {obj.put("dynamic", obj2);obj.put("doubt", obj3);obj.put("courses", obj4);}break;default:break;}eventType = parser.next();}} catch (XmlPullParserException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();} catch (JSONException e) {e.printStackTrace();} finally {try {inputStream.close();} catch (IOException e) {e.printStackTrace();}}return obj.toString();}}

activity，此处练手不考虑效率，直接放在主线程中了：

package com.tudou.activity.work3;import com.tudou.activity.R;import android.app.Activity;import android.os.Bundle;import android.util.Log;public class HomeWork3 extends Activity {String path = "http://software.webtrn.cn/cms/res_base/software_webtrn_cn/privacy/config/tyxl/appConfiguration.xml";@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.homework3);}@Overrideprotected void onStart() {super.onStart();String result = XmlParser.getXML(HttpUtil.getInputStream(path), "utf-8");Log.d("mylog", "result:" + result);}}

顺便贴一个练手的界面。
