DomCrawler Component
====================
If you are familiar with jQuery, DomCrawler is a PHP equivalent.
It allows you to navigate the DOM of an HTML or XML document:
```
use Symfony\Component\DomCrawler\Crawler;
$crawler = new Crawler();
$crawler->addContent('<html><body><p>Hello World!</p></body></html>');
print $crawler->filterXPath('descendant-or-self::body/p')->text();
