XML转JSON

Step 1 : 下载 java-json.jar

http://www.java2s.com/Code/JarDownload/java/java-json.jar.zip

Step 2: 增加 java-json.jar 到/libs目录并add to build path.

Step 3: 测试demo

例子：

package test;


import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import org.json.XML;


public class Test {
public static String signData = "<?xml version=\"1.0\" encoding=\"utf-8\"?><BodSignData version=\"1.0\"><Field><Name>orderId</Name><DispName></DispName><Value>5001</Value></Field><Field><Name>payAccountNo</Name><DispName>kevin</DispName><Value>590000113004775</Value></Field><Field><Name>amount</Name><DispName>undefined</DispName><Value>520</Value></Field><Field><Name>masterName</Name><DispName>undefined</DispName><Value>sn</Value></Field><Field><Name>payDate</Name><DispName>undefined</DispName><Value>20150704</Value></Field></BodSignData>";

public static void main(String[] args) {
/*JSONObject jsonObj = null;
try {
jsonObj = XML.toJSONObject(signData);
JSONObject jsonBodSignData = jsonObj.getJSONObject("BodSignData");
System.err.println(jsonBodSignData.toString());
JSONArray jsonField=jsonBodSignData.getJSONArray("Field");
System.err.println(jsonField);
for (int i = 0; i < jsonField.length(); i++) {
System.err.println(jsonField.get(i));
}
} catch (JSONException e) {
e.printStackTrace();
} 
Log.e("XML", signData);
Log.e("JSON", jsonObj.toString());
//System.err.println(signData);
//System.err.println(jsonObj.toString());
*/
String resp="<?xml version=\"1.0\" encoding=\"utf-8\"?><request><filelist><treenode><!--code 0表示成功--><code>0</code></treenode></filelist></request>";
try {
JSONObject jsonObj = XML.toJSONObject(resp);
JSONObject jsonRequest = jsonObj.getJSONObject("request");
JSONObject jsonfilelist=jsonRequest.getJSONObject("filelist");
JSONObject jsontreenode=jsonfilelist.getJSONObject("treenode");
int jsoncode=jsontreenode.getInt("code");
System.err.println(jsoncode);
} catch (JSONException e) {
e.printStackTrace();
} 

}
}
