Error: The current node list is empty

[Ande1232]

Hi, I'm estract out the metacritic of the game, only if the game does not have a metacritic, it shows me the error:

(1/1) InvalidArgumentExceptionThe current node list is empty.
--
in Crawler.php (line 584)

This is my code. (Checkoline is a feature that you can see here)

if (checkOnline('http://www.metacritic.com/game/'.str_slug($console->nome_cat, '-').'/'.$giochi->slug))
{
  $client = new Client();

  $crawler = $client->request(
      'GET',
      'http://www.metacritic.com/game/'.str_slug($console->nome_cat, '-').'/'.$giochi->slug
  );
  $metacritic = $crawler->filterXPath('//*[@id="main"]/div/div[3]/div/div/div[2]/div[1]/div[1]/div/div/a/div/span')->html();
}

If the page exists he prints me correctly the metascore, but how do I do that if it does not exist ignore the crawler?

Try wrapping your code in a try-catch statement.

try
{
  if (checkOnline('http://www.metacritic.com/game/'.str_slug($console->nome_cat, '-').'/'.$giochi->slug))
  {
    $client = new Client();
    
    $crawler = $client->request(
        'GET',
        'http://www.metacritic.com/game/'.str_slug($console->nome_cat, '-').'/'.$giochi->slug
    );
    $metacritic = $crawler->filterXPath('//*[@id="main"]/div/div[3]/div/div/div[2]/div[1]/div[1]/div/div/a/div/span')->html();
  }
}
catch (Exception $e) {/* echo 'error'; */}
