Custom logic for process RSS

Maybe you need your custom logic for feed process. In this case you need to create a custom processor that implements ProcessorInterface

<?php

use Desarrolla2\RSSClient\Parser\Processor\ProcessorInterface;

class CustomProcessor implements ProcessorInterface
{
    /**
     * [@var](https://github.com/var) array
     */
    protected $mediaTypes = array(
        'content',
        'keywords',
        'thumbnail',
        'category',
        'comments',
    );

    /**
     * [@param](https://github.com/param) NodeInterface $node
     * [@param](https://github.com/param) \DOMElement   $item
     *
     * [@return](https://github.com/return) mixed|void
     */
    public function execute(NodeInterface $node, \DOMElement $item)
    {
        foreach ($this->mediaTypes as $mediaType) {
            /* Implement getNodeValueByTagName yourself */
            $value = $this->getNodeValueByTagName($item, $mediaType);
            if ($value) {
                $node->setExtended(
                    $mediaType,
                    $value
                );

            }
        }
    }
}

And them push it on the top of processors stack.

<?php

use Desarrolla2\RSSClient\RSSClient;

$client = new RSSClient();
$client->pushProcessor( new CustomProcessor($client->getSanitizerHandler()));

Now you can continue normally.

<?php

$client->fetch();
