How to find HTML elements by attribute using DOM Crawler?

You can find HTML elements by attribute using DOM Crawler by utilizing the filterXPath method with an XPath selector that includes an attribute selector. Here's an example that uses the filterXPath method with an XPath selector to find all input elements on ScrapingBee's login page that have a type attribute equal to "email":

use Symfony\Component\DomCrawler\Crawler;
use GuzzleHttp\Client;

// Create a client to make the HTTP request
$client = new \GuzzleHttp\Client();
$response = $client->get('https://app.scrapingbee.com/account/login');
$html = (string) $response->getBody();

// Load the HTML document
$crawler = new Crawler($html);

// Find all input elements with a type attribute equal to "email"
$textInputs = $crawler->filterXPath('//input[@type="email"]');

// Loop over the inputs and print their values
foreach ($textInputs as $input) {
    echo $input->getAttribute('placeholder') . PHP_EOL;
}

// Output:
// Enter your email

Note: This example uses Guzzle so you may have to install it.
