How to Remove `` Tags from HTML Content?

Removing Script Tags from HTML Content

Question:

How can I selectively remove only tags from HTML content without affecting other formatting?

Answer:

Using Regular Expressions (Regex)

While not recommended for parsing HTML, a simple regex can be used to remove tags:

$html = preg_replace('# (.*?) #is', '', $html); Using DOMDocument:

A more reliable and safer approach is to use the DOMDocument class:

$dom = new DOMDocument(); $dom->loadHTML($html); $script = $dom->getElementsByTagName('script'); $remove = []; foreach($script as $item) { $remove[] = $item; } foreach ($remove as $item) { $item->parentNode->removeChild($item); } $html = $dom->saveHTML(); Additional Options:

Using PHP's Native strip_tags() Function

While it doesn't selectively remove tags, it can be used to remove all HTML tags:

$html = strip_tags($html, ' '); Using HTML Purifier

If you wish to perform comprehensive HTML parsing and security measures, consider using the HTML Purifier library:

$config = HTMLPurifier_Config::createDefault(); $config->set('Core.RemoveScript', true); $purifier = new HTMLPurifier($config); $html = $purifier->purify($html);
