How to parse content like CMS page in custom block in Magento 2

In this blog I’ll explain how can you parse content like CMS page. That means parsing the content of WYSIYG editor, parsing contents like shown below,

{{media url="wysiwyg/test.jpg"}}

{{config path="trans_email/ident_custom2/name"}}

{{widget type="Magento\Cms\Block\Widget\Block" template="widget/static_block/default.phtml" block_id="4"}}

{{block class="Magento\Framework\View\Element\Template" name="test" template="Magento_Catalog::product/widget/test.phtml"}}

To parse the content like these you need to get the \Magento\Cms\Model\Template\FilterProvider instance and call the getBlockFilter() or getPageFilter() as shown below,

public function __construct(
    .....
    \Magento\Cms\Model\Template\FilterProvider $filterProvider,
    .....
) {
    .....
    $this->filterProvider = $filterProvider;
    .....
}
   
public function getCMSContent()
{
    .....
    $parsedContent = $this->filterProvider->getPageFilter()->filter($content);    //$content is the content that you want to parse
    return $parsedContent;
}
