从Web到android获取xml数据时面临困难

Question

I need some help with this.

I have a xml file hosted at http://t3.netne.net/test.xml the xml file looks like this :

<?xml version="1.0" encoding="UTF-8"?>
<game>
    <stat>
      <varx>5</varx>
      <vary>10</vary>
    </stat>
</game>

now I need that value of varx and vary in my android app.

This is what I did so far:

public class MultiPlayerGameMenuActivity extends Activity {
    String url = "http://t3.netne.net/test.xml";
    ProgressDialog pDialog;
    String msgx = "x";
    String msgy = "y";

    public void HostNewGameButtonClicked(View view){


        Toast t = new Toast(this);
        t.setText(msgx+"    "+msgy);
        t.setDuration(1000);
        t.show();

    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_multi_player_game_menu);

        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
             new GetXml(url).executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, new String[]{null});
        else
            new GetXml(url).execute(new String[]{null});

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.multi_player_game_menu, menu);
        return true;
    }

    public class GetXml extends AsyncTask<String, Void, String>{
        String urls;

        public GetXml(String urls){
            this.urls = urls;
        }

        @Override
        protected void onPreExecute(){
            pDialog = ProgressDialog.show(MultiPlayerGameMenuActivity.this, "Fetching Details... ", "Please Wait...", true);

        }

        @Override
        protected String doInBackground(String... params){
            URL url;
            try{
                url = new URL(urls);
                DocumentBuilderFactory mDocumentBuilderFactory = DocumentBuilderFactory.newInstance();
                DocumentBuilder mDocumentBuilder = mDocumentBuilderFactory.newDocumentBuilder();
                Document mDocument = mDocumentBuilder.parse(new InputSource(url.openStream()));

                mDocument.getDocumentElement().normalize();

                NodeList mNodeList = mDocument.getElementsByTagName("stat");

                for(int i=0;i<mNodeList.getLength();i++){
                    Node mNode = mNodeList.item(i);

                    Element mElement = (Element) mNode;
                    NodeList mStringList = mElement.getElementsByTagName("varx");
                    Element strElement = (Element) mStringList.item(0);
                    mStringList = strElement.getChildNodes();

                    msgx = mStringList.item(0).getNodeValue();

                    NodeList mStringList2 = mElement.getElementsByTagName("vary");
                    Element strElement2 = (Element) mStringList2.item(0);
                    mStringList2 = strElement2.getChildNodes();

                    msgy = mStringList.item(0).getNodeValue();
                }
            }catch(MalformedURLException e){
                e.printStackTrace();
            }catch(ParserConfigurationException e){
                e.printStackTrace();
            }catch(SAXException e){
                e.printStackTrace();
            }catch(IOException e){
                e.printStackTrace();
            }
                return null;
        }

        @Override
        protected void onPostExecute(String result){
            if(pDialog.isShowing())
                pDialog.dismiss();
        }

    }

}
