I am trying to retrieve the search results from YouTube suggestions using Selenium webdriver (Java) but i am getting the following error. Please help.

Error:

    }

How on earth do you want to do that from UI level? Is there a reason you can't use Youtube API? - Yi Zeng
I am trying to do something similar to the code @ code.google.com/p/selenium/wiki/GettingStarted, which works but the youtube suggestion isn't working. This is more for automation using web driver. - kasukur
YouTube or even any Google based site, is just awful to use for site automation. I'd try something different, if all you are attempting to do is use WebDriver on something. - Arran

Try with below logic to get the youtube search results after loading URL .

driver.findElement(By.name("search_query")).sendKeys("Selenium WebDriver"+Keys.ENTER);
List<WebElement> search_result=driver.findElements(By.cssSelector("#results ol#search-results>li h3>a"));
for(WebElement each_result:search_result) {
   System.out.println(each_result.getAttribute("title"));
}

it seems that since the time of writing the tutorial google has changed the element class names. The changes below worked for me. 

WebElement resultsDiv = driver.findElement(By.className("sbsb_a"));
 List allSuggestions = driver.findElements(By.xpath("//li[@class='sbsb_c gsfs']"));
