How to disable span tag/allow only p tag via HtmlPurifier?

Question

Yii

The text for the block on the site is filled through the admin panel, where it is possible to edit the text styles. In my case, I would like it not to be displayed. Now the text on the page looks like this:

<p>
<span style="font-size:24pt;"> текст </span>
</p>

Tried

<?php HtmlPurifier::process($text->getText(), function ($config) {
                                            $config->getHTMLDefinition(true)->addAttribute('p', 'class', 'Text');
                                        });?>

Does not work.
What are the solutions?

Answer 1

We solved the problem with a regular expression:
preg_replace('/\s?style=["][^"]*"\s?/i', ' ', $text)
