strip_anchors

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.

Sample output:

<!-- 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.

Usage

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:

Example:

{{ item.content|strip_anchors }}

Example 2: use in combination with another filter

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

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