1. 8.0 core/lib/Drupal/Core/Field/AllowedTagsXssTrait.php \Drupal\Core\Field\AllowedTagsXssTrait::fieldFilterXss()

Filters an HTML string to prevent XSS vulnerabilities.

Like \Drupal\Component\Utility\Xss::filterAdmin(), but with a shorter list of allowed tags.

Used for items entered by administrators, like field descriptions, allowed values, where some (mainly inline) mark-up may be desired (so \Drupal\Component\Utility\Html::escape() is not acceptable).

Parameters

string $string: The string with raw HTML in it.

Return value

\Drupal\Component\Utility\SafeMarkup An XSS safe version of $string, or an empty string if $string is not valid UTF-8.
