Cannot Resolve Symbol at setText

I want to build a RSS Reader but I am getting a 'cannot resolve symbol' error in my onStart Method at mRssFeed.setText(rssFeed) where it has a problem with the mRssFeed. Here is my whole class:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.feed_fragment_portrait, container, false);
    TextView mRssFeed = (TextView) rootView.findViewById(R.id.rss_feed);
    return rootView;
}
@Override
public void onStart() {
    super.onStart();
    InputStream in = null;
    try {
        URL url = new URL("http://www.androidpit.com/feed/main.xml");
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        in = conn.getInputStream();
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        byte[] buffer = new byte[1024];
        for (int count; (count = in.read(buffer)) != -1; ) {
            out.write(buffer, 0, count);
        }
        byte[] response = out.toByteArray();
        String rssFeed = new String(response, "UTF-8");
        mRssFeed.setText(rssFeed);
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (in != null) {
            try {
                in.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

Can someone please help me with this?

The variable mRSSfeed is declared inside onCreateView so onStart cannot access it.

Declare it outside the method inside the Class instead like this

TextView mRssFeed;

Then in onCreateView change the line to

mRssFeed = (TextView) rootView.findViewById(R.id.rss_feed);
