If you have a string which contains HTML you can use Jsoup library like this to get HTML elements:
String htmlTable= "<table><tr><td>Hello World!</td></tr></table>";
Document doc = Jsoup.parse(htmlTable);
// then use something like this to get your element:
Elements tds = doc.getElementsByTag("td");
// tds will contain this one element: <td>Hello World!</td>
Good luck!
