I need to get the result from the table \"td\". But before I can do that I need to navigate a frame that contains it. The frame is one of the frameset elements that belongs
Through chaining methods together, once you switchTo().defaultContent, you can create temporary lists of available frames through findElements() by tagName and go to that specific frames' index...
For example
driver.switchTo()defaultContent();
driver.switchTo().frame(driver.findElement(By.tagName("frameset")).findElements(By.tagName("frame")).get(2));
