HTMLPurifierX is a small wrapper around original ezyang/htmlpurifier library, providing a few more customization options. It is also compatible with xemlock/htmlpurifier-html5.

It extends configuration options to allow following features that can't be accomplished otherwise, because htmlpurifier follows a design principle based on whitelisting single elements and attributes.

• Allow all data-* attributes on elements, since they are harmless and used very often.

    $configObject->set("HTML.AllowDataAttributes", true);
  

• Allow namespaced attributes like "xxx:yyyyyy" on elements, since they are used in modern frameworks.

    $configObject->set("HTML.AllowNamespacedAttributes", true);
  

• Allow all custom element names that satisy a regex, since they are widely used in web components and modern frameworks. A common use case would be to allow all elements with a user defined prefix.

    $configObject->set("HTML.AllowCustomElements", true);
    // default "": means allow all custom elements.
    $configObject->set("HTML.AllowCustomElementsRegex", "/^x-/");
  

Check examples to see how it works.

Installation

composer require ardabeyazoglu/htmlpurifierx

This will also install original ezyang/htmlpurifier library if not already installed.

Why not fork ?

The customizations made here might be against the design principles of original library. It is easier and faster to provide them as an extra layer.
