Thanks for this. Awesome example.
+1 Thanks
Thank you, man with a glorious beer
👍
much appreciated
Since each() gets one node at a time, this has the same effect:
$crawler->filter('html .content h2')->each(function (Crawler $crawler) {
$node = $crawler->getNode(0);
$node->parentNode->removeChild($node);
});IMO this is more readable

👍 Nice catch

@NinoSkopac I am aware that it has been several years since your message, but for anyone stumbling across this thread as I have, be aware that you can't use this method in WebDriver mode now. You get the following error:
Uncaught InvalidArgumentException: The "getNode" method cannot be used in WebDriver mode. Use "getElement" instead.
You're amazing thanks!!
