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";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.homework3);
}
@Override
protected 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。
