The strip_anchors Twig (v.2.5.0) filter removes all anchor links (ie. links pointing to different sections of the same page where they are located) from input.

<!-- BEFORE applying filter: -->
<h2><a href="#features">Features of this Twig Extension</a></h2>

<!-- AFTER applying `strip_anchors` filter: -->
<h2>Features of this Twig Extension</h2>

Please note: This repository only shows directories and files from a Symfony 4 skeleton project that need to be added or modified to enable the 'strip_anchors' Twig extension.

Use this Twig filter in an RSS feed template to help transform HTML input into valid RSS 2.0, as shown in the following examples:

{{ item.content|strip_anchors }}

<-- excerpt from rss.xml.twig: -->

<content:encoded>
   <![CDATA[
    {{ item.content|md2html|strip_anchors }}
   ]]>
</content:encoded>

This repository shows how this custom Twig extension (ie. the strip_anchors Twig filter) can be implemented in a Symfony 4 project structure created using symfony/skeleton.

• PHP (v.7.1.16)
• Composer (v.1.6.5)
  • symfony/skeleton (v.4.1.4.2)
  • symfony/twig-bundle (v.4.1.4)
  • symfony/web-server-bundle (optional: for dev environment)
  • phpunit/phpunit (v.7.3) OR symfony/phpunit-bridge, symfony/test-pack

(Copyrights for the above remain with their respective owners.)

• Create a new project:

$ composer create-project symfony/skeleton my-project

• Clone this repository (as shown below) and make the corresponding modifications:

$ git clone https://github.com/hfagerlund/strip_anchors.git

$ php bin/console server:run

From the project root dir, run one of the following:

$ ./vendor/phpunit/phpunit/phpunit ./tests/

Or (recommended):

$ ./bin/phpunit
