Catch url and follow it in webview?

Question

Android

Hey!
We load a document into the webview, you need to find the url in it and follow it.

import java.util.logging.Level;
import java.util.logging.Logger;
import javafx.application.Application;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.concurrent.Worker.State;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;
import javafx.stage.Stage;
/*from w w w  . j  a v  a2s .  c  o  m*/
public class Main extends Application {
  public static void main(String[] args) {
    Application.launch(args);
    
  }
private Scene scene;
  @Override
  public void start(Stage stage) {
      
   WebView browser = new WebView();
        final WebEngine webEngine = browser.getEngine();
        
        webEngine.getLoadWorker().stateProperty().addListener(
        new ChangeListener<State>() {
            public void changed(ObservableValue ov, State oldState, State newState) {
                if (newState == State.SUCCEEDED) {

                }
            }
        });
        
        webEngine.load("https://mail.ru");
        
        scene = new Scene(browser,1024,600, Color.web("#666970"));
        stage.setScene(scene);       
        stage.show();
        
  }
}

It turns out to click on the link if the tag has its own ID.

if (newState == State.SUCCEEDED) {
webEngine.executeScript("document.getElementById('ph_mail').click()");
                }

How to do the same if there is no ID ?
