Take out the scraped result of JSoup (using Async task) and convert it to a String that I can use it on my external class

Question

I need to get values from internet using AsyncTask and JSoup, I want to convert the scraped data from JSoup an make them into a String I can use later on my class to build a List. I was wondering if I can create a String from the JSoup result inside the AsyncTask and use it on an external class? I was thinking on something like this:

String url = "http://mysite.com.data.php";
public class Title extends AsyncTask<Void, Void, Void> {
    String title;
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
    }
    @Override
    protected Void doInBackground(Void... params) {
        try {
            // Connect to the web site
            Document document = Jsoup.connect(url).get();
            // Get the html document title
            title = document.title();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }
    @Override
    protected void onPostExecute(Void result) {
        String myString = title; //<---TAKE THIS STRING FROM HERE
    }//                                       |
}//                                           V
String my2ndString = myString; //<---------AND USE IT HERE
