# Symfony 7.4 DomCrawler Component
GitHub: https://github.com/symfony/dom-crawler
Docs: https://symfony.com/doc/7.4/components/dom_crawler.html
## Quick Reference
### Installation
```bash
composer require symfony/dom-crawler
# For CSS selector support:
composer require symfony/css-selector
```
### Creating a Crawler
```php
use Symfony\Component\DomCrawler\Crawler;
$crawler = new Crawler($html);
// Or add content later:
$crawler = new Crawler();
$crawler->addHtmlContent('Hello
');
$crawler->addXmlContent('');
```
### Filtering with CSS Selectors & XPath
```php
// CSS selectors (requires symfony/css-selector)
$crawler->filter('body > p');
$crawler->filter('.message');
$crawler->filter('#main-content a.link');
// XPath
$crawler->filterXPath('descendant-or-self::body/p');
// Reduce with callback
$crawler->filter('p')->reduce(function (Crawler $node, $i): bool {
return ($i % 2) === 0;
});
```
### Traversing Nodes
```php
$crawler->filter('p')->eq(0); // By position
$crawler->filter('p')->first(); // First node
$crawler->filter('p')->last(); // Last node
$crawler->filter('p')->siblings(); // Siblings
$crawler->filter('p')->nextAll(); // Next siblings
$crawler->filter('p')->previousAll(); // Previous siblings
$crawler->filter('body')->children(); // Children
$crawler->filter('p')->ancestors(); // Ancestors
$crawler->filter('p')->closest('div');// Closest matching parent
```
### Extracting Values
```php
$crawler->filter('p')->text(); // Text content
$crawler->filter('p')->text('Default'); // With default
$crawler->filter('p')->innerText(); // Direct text only
$crawler->filter('p')->attr('class'); // Attribute
$crawler->filter('p')->attr('class', 'default'); // Attr with default
$crawler->filter('p')->nodeName(); // Tag name
$crawler->filter('p')->html(); // Inner HTML
$crawler->filter('p')->outerHtml(); // Outer HTML
$crawler->filter('p')->extract(['_name', '_text', 'class']); // Multiple
$crawler->filter('p')->each(function (Crawler $node, $i) {
return $node->text();
});
```
### Working with Forms
```php
$form = $crawler->selectButton('Submit')->form();
$form = $crawler->selectButton('Submit')->form([
'name' => 'Ryan',
]);
$form['registration[username]']->setValue('symfonyfan');
$form['registration[terms]']->tick();
$form['registration[birthday][year]']->select(1984);
$form['registration[photo]']->upload('/path/to/file.jpg');
$uri = $form->getUri();
$method = $form->getMethod();
$values = $form->getPhpValues();
$files = $form->getPhpFiles();
```
### Working with Links & Images
```php
$link = $crawler->selectLink('Log in')->link();
$uri = $link->getUri();
$image = $crawler->selectImage('Kitten')->image();
$uri = $image->getUri();
```
### URI Resolution
```php
use Symfony\Component\DomCrawler\UriResolver;
UriResolver::resolve('/foo', 'http://localhost/bar/foo/');
// http://localhost/foo
```
