I want to add those web links in a arraylist.
suggest me some way out for it.. Even any link or tutorials related to this will be helpful. Thanks.

here is full code..

public class MainActivity extends Activity {


    String xmlurl       = "--url of xml---";


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ArrayList<String> mImageLink = new ArrayList<String>();
        try {
            URL url = new URL(xmlurl);
            XMLParser   parser  =   new XMLParser();
            String      xml     = parser.getXMLfromUrl(url);
            Document    doc     = parser.getDomElement(xml);
            DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
            DocumentBuilder db = dbf.newDocumentBuilder();
            Document doc1 = db.parse(new InputSource(url.openStream()));
            doc1.getDocumentElement().normalize();

            NodeList nodeList = doc1.getElementsByTagName("photo");

            for (int i = 0; i < nodeList.getLength(); i++) {
                Element websiteElement = (Element) nodeList.item(i);
                nodeList = websiteElement.getChildNodes();              
                mImageLink.add(websiteElement.getAttribute("link"));

            }
        } catch (Exception e) {
            System.out.println("XML Pasing Excpetion = " + e);
        }

        for(int i=0;i<mImageLink.size();i++){
            Log.d("Photo link --- " + i,mImageLink.get(i));
        }

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
}

Please Use below code to Parse above XML file using DOM Parser.

public class MainActivity extends Activity {

    ArrayList<String> mImageLink;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        try {
            mImageLink = new ArrayList<String>();

            InputStream is = getResources().openRawResource(R.raw.temp);
            DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
            DocumentBuilder db = dbf.newDocumentBuilder();
            Document doc = db.parse(new InputSource(is));
            doc.getDocumentElement().normalize();

            NodeList nodeList = doc.getElementsByTagName("image");

            for (int i = 0; i < nodeList.getLength(); i++) {

                Node node = nodeList.item(i);

                Element fstElmnt = (Element) node;

                mImageLink.add(fstElmnt.getAttribute("link"));

            }
        } catch (Exception e) {
            System.out.println("XML Pasing Excpetion = " + e);
        }
    }
}
