try {
            //set the download URL, a url that points to a file on the internet
            //this is the file to be downloaded
            URL url = new URL("http://IP/Downloads/data.xml");

            //create the new connection
            HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();



            //and connect!
            urlConnection.connect();

            //set the path where we want to save the file
            //in this case, going to save it on the root directory of the
            //sd card.
            File SDCardRoot = Environment.getExternalStorageDirectory();
            //create a new file, specifying the path, and the filename
            //which we want to save the file as.
            File file = new File(SDCardRoot,"data.xml");

            //this will be used to write the downloaded data into the file we created
            FileOutputStream fileOutput = new FileOutputStream(file);

            //this will be used in reading the data from the internet
            InputStream inputStream = urlConnection.getInputStream();

            //this is the total size of the file
            int totalSize = urlConnection.getContentLength();
            progressDialog.setMax(totalSize);

            //variable to store total downloaded bytes
            int downloadedSize = 0;

            //create a buffer...
            byte[] buffer = new byte[1024];
            int bufferLength = 0; //used to store a temporary size of the buffer

            //now, read through the input buffer and write the contents to the file
            while ( (bufferLength = inputStream.read(buffer)) > 0 ) {
                    //add the data in the buffer to the file in the file output stream (the file on the sd card
                    fileOutput.write(buffer, 0, bufferLength);
                    //add up the size so we know how much is downloaded
                    downloadedSize += bufferLength;

            }
            //close the output stream when done
            fileOutput.close();
            //catch some possible errors...
    } catch (MalformedURLException e) {
            e.printStackTrace();
    } catch (IOException e) {
            e.printStackTrace();
    }

Try this code for downloading your xml file and check this tutorial for reading xml http://www.java-samples.com/showtutorial.php?tutorialid=152

Better way to read it in String and do whatever you want to do with it.

public String getXmlFromUrl(String url) {
String xml = null;

try 
{
    //default http client
    HttpClient httpClient = new DefaultHttpClient();

    HttpPost httpPost = new HttpPost(url);

    System.out.println("URL IN PARSER:==="+url+"====");

    HttpResponse httpResponse = httpClient.execute(httpPost);

    HttpEntity httpentity = httpResponse.getEntity();

    xml = EntityUtils.toString(httpentity);   // I have changed it... because  occur while downloading..

    Log.d("response", xml);
} 
catch(UnsupportedEncodingException e)
{
    e.printStackTrace();
} 
catch (ClientProtocolException e) 
{
    e.printStackTrace();
} 
catch (IOException e) 
{
    e.printStackTrace();
}


return xml;

}
