How to replace a body in html file

I'm using android studio

I need to replace the body of an html document with other codes, this is an example that I tried to follow

protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.grafico);

wv = (WebView) findViewById(R.id.prova);
wv.setWebViewClient(new MyWebViewClient());

new BackgroundWorker().execute();



// load links in WebView instead of default browser
private class MyWebViewClient extends WebViewClient

@Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
view.loadUrl(url);
return false;


@RequiresApi(21)
@Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request)
view.loadUrl(request.getUrl().toString());
return false;



private class BackgroundWorker extends AsyncTask<Void, Void, Void> {

@Override
protected Void doInBackground(Void... arg0)
getDarewod();
return null;


public void getDarewod()

try
Document htmlDocument = Jsoup.connect(url).get();
Element element = htmlDocument.select("#gkHeaderMod > div.grafico-quotazione").first();

// replace body with selected element


htmlDocument.body().empty().append(element.toString());
final String html = htmlDocument.toString();

uiHandler.post(new Runnable()
@Override
public void run()
wv.loadData(html, "text/html", "UTF-8");

);
catch (IOException e)
e.printStackTrace();

element.toString()

append

innerHTML = ...
