Removing nodes

[duncanmcclean]

Hi,

Is there any way using Goutte to remove nodes? I'm building a parser but I need to remove header and footer elements, along with others.

I've briefly looked at the source code for Symfony Crawler and I found the reduce function but I'm unsure on how to use it.

$node->parentNode->removeChild($node); will do it :)

Hopefully it makes ReadCast an even better software :)

Do I put that inside a filter @NinoSkopac?

No, in the callback closure.

Sorry, I don't understand. Do you mind providing an example?

I have just attempted to do this using this code:

$crawler
                ->filter('nav, header, #nav, #header')
                ->each(function ($node) use (&$body) {
                    $node->parentNode->removeChild($node);
                });

With that I get the error message, Undefined property: Symfony\Component\DomCrawler\Crawler::$parentNode

the argument of the each method is a Crawler object, not a DomElement node. You need to get the node out of it.

Exactly, typehint it like this: function (Crawler $node) { ...calback code... }

And you can get the node out of it thus: $node->getNode(0);

Thanks for your help! Managed to achieve it!

$crawler
                ->filter('head, script, nav, header, #nav, #header, .navbar, #navbar, footer, .footer #foorer, .sidebar, #sidebar, .comments, #comments, .pagination, button')
                ->each(function (Crawler $crawler) {
                    foreach ($crawler as $node) {
                        $node->parentNode->removeChild($node);
                    }
                });
