The DOM Crawler

Symfony 5.3 is backed by JoliCode.

The DOM Crawler

A Crawler instance is returned each time you make a request with the Client. It allows you to traverse HTML or XML documents: select nodes, find links and forms, and retrieve attributes or contents.


Like jQuery, the Crawler has methods to traverse the DOM of an HTML/XML document. For example, the following finds all input[type=submit] elements, selects the last one on the page, and then selects its immediate parent element:

$newCrawler = $crawler->filter('input[type=submit]')

Many other methods are also available:

Nodes that match the CSS selector.
Nodes that match the XPath expression.
Node for the specified index.
First node.
Last node.
All following siblings.
All preceding siblings.
Returns the parent nodes.
Returns children nodes.
Nodes for which the callable does not return false.

Since each of these methods returns a new Crawler instance, you can narrow down your node selection by chaining the method calls:

    ->reduce(function ($node, $i) {
        if (!$node->attr('class')) {
            return false;


Use the count() function to get the number of nodes stored in a Crawler: count($crawler)

Extracting Information

The Crawler can extract information from the nodes:

// returns the attribute value for the first node

// returns the node value for the first node

// returns the default text if the node does not exist
$crawler->text('Default text content');

// pass TRUE as the second argument of text() to remove all extra white spaces, including
// the internal ones (e.g. "  foo\n  bar    baz \n " is returned as "foo bar baz")
$crawler->text(null, true);

// extracts an array of attributes for all nodes
// (_text returns the node value)
// returns an array for each element in crawler,
// each with the value and href
$info = $crawler->extract(['_text', 'href']);

// executes a lambda for each node and return an array of results
$data = $crawler->each(function ($node, $i) {
    return $node->attr('href');
