// ]

VarDumper::dump($crawler->filterXPath('//span[@class="article"]')->evaluate('count(@id)'));
// array:3 [
//   0 => 1.0
//   1 => 1.0
//   2 => 1.0

VarDumper::dump($crawler->evaluate('count(//span[@class="article"])'));
// array:1 [
//   0 => 3.0
// ]

VarDumper::dump($crawler->evaluate('//span[1]'));
// Symfony\Component\DomCrawler\Crawler { }
