Convert XML file using XSLT in Android

Question

I am new to Android.

I want to convert a XML file to HTML format using XSLT to display it in android.

Can you please tell me some tutorials or examples to follow?

I also tried the codes in the Android: Convert xml using xslt But it didn't work. I am not sure what is "StringOutputStream" there.

Thanks in advance.

Put both your xml and xslt file in raw folder. The generated html file will be stored in sdcard. Use the following code.

import java.io.File;

import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.TransformerFactoryConfigurationError;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;

import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;

public class XsltTester extends Activity {

    private static String TAG = XsltTester.class.getSimpleName();

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        try {

            Source xmlSource = new StreamSource(this.getResources().openRawResource(R.raw.weather));
            Source xsltSource = new StreamSource(this.getResources().openRawResource(R.raw.weatherxsl));

            TransformerFactory transFact = TransformerFactory.newInstance();
            Transformer trans = transFact.newTransformer(xsltSource);
//          FileOutputStream fo = new FileOutputStream(f);
//          fo.write(resizeBitMapImageToByteArray(photoAlbumBean));
//          fo.close();
            File f = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/mydata.html");

//            OutputStream output = new StringOutputStream();
            StreamResult result = new StreamResult(f);
            trans.transform(xmlSource, result);

        } catch (TransformerConfigurationException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (TransformerFactoryConfigurationError e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (TransformerException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

Thanks Deepak

Don't forget to add:

< uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 

to the AndroidManifest.xml as this noob eventually found out :)
