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。
