Возможен ли двойной парсинг в Activity или это неправильно?

public class MainActivity extends Activity {
TextView textview;
NodeList nodelist;
ProgressDialog pDialog;
String url;
String DetailText;
String URL = "Тут адрес xml";

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
textview = (TextView) findViewById(R.id.text);
new DownloadXML().execute(URL);
}

private class DownloadXML extends AsyncTask<String, Void, Void> {

@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(MainActivity.this);
pDialog.setTitle("Loading...");
pDialog.setMessage("Wait...");
pDialog.setIndeterminate(false);
pDialog.show();
}

@Override
protected Void doInBackground(String... Url) {
try {
URL url = new URL(Url[0]);
DocumentBuilderFactory dbf = DocumentBuilderFactory
.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new InputSource(url.openStream()));
doc.getDocumentElement().normalize();
nodelist = doc.getElementsByTagName("point");

} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
return null;

}

@Override
protected void onPostExecute(Void args) {

for (int temp = 0; temp < nodelist.getLength(); temp++) {
Node nNode = nodelist.item(temp);
if (nNode.getNodeType() == Node.ELEMENT_NODE) {
Element eElement = (Element) nNode;
textview.setText(textview.getText() + getNode("point", eElement) + "\n" + "\n");
textview.setText(textview.getText() + getNode("name", eElement) + "\n" + "\n");
textview.setText(textview.getText() + getNode("id", eElement) + "\n" + "\n");

Здесь нужно спарсить и вставить картинку с HTML страницы

}
}
pDialog.dismiss();
}
}


private static String getNode(String sTag, Element eElement) {
NodeList nlList = eElement.getElementsByTagName(sTag).item (0)
.getChildNodes();
Node nValue = (Node) nlList.item(0);
return nValue.getNodeValue();
}
