Reading from the nasa feed rss file throws SAXException

Question

I am trying to use the simple-framework in android to read a file which I take from the nasa feed. The nasa file is here: http://www.nasa.gov/rss/dyn/image_of_the_day.rss

The way I go around this is by using the following code:

Serializer serialezr = new Persister();



        String file_path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/nasa";
        try{
            File dir = new File(file_path);
            if(!dir.exists())
            {
                dir.mkdirs();
            }
            File nasa = new File(file_path,filename);
            if(nasa.exists())
            {
                nasa.delete();
            }
            nasa.createNewFile();
            source = new File(file_path + "/" + filename);


        }
        catch(Exception e)
        {
            StringWriter sw = new StringWriter();
            PrintWriter pw = new PrintWriter(sw);
            e.printStackTrace(pw);

            view.setText(sw.toString() + "here");
        }

The above code creates the nasa.xml file in a directory which I will later use

    DefaultHttpClient httpclient = new DefaultHttpClient();
    HttpGet httpget = new HttpGet("http://www.nasa.gov/rss/dyn/image_of_the_day.rss");
    HttpResponse response = httpclient.execute(httpget);
            HttpEntity ht = response.getEntity();

            BufferedHttpEntity buf = new BufferedHttpEntity(ht);

            InputStream is = buf.getContent();


            BufferedReader r = new BufferedReader(new InputStreamReader(is));

            StringBuilder total = new StringBuilder();
            String line;
            while ((line = r.readLine()) != null) {
                total.append(line + "\n");
            }



            FileUtils.writeStringToFile(source,total.toString());

The above code actually gets the file from their website using a DefaultHttpClient.

"Googling" this I have discovered that the xml file might not be written properly? Looking at the xml file from nasa I cannot see any "<>" tags which appeared to be the most common error that throws this exception.

UPDATES

• Instead of using BufferedReader and appending a line after a line I have used InputStreamReader to read each character. It runs out of memory
• Looks like if I take out the ImageView from the layout everything works even the xml parsing.
