1. 8.3 standard/src/Plugin/XBBCode/CodeTagPlugin.php \Drupal\xbbcode_standard\Plugin\XBBCode\CodeTagPlugin::prepare()

Transform an elements' content, to armor against other filters.

• Use the inner content if all children will be rendered. (This just means the children's own ::prepare() functions are used.)
• Use $tag->getSource() if no children will be rendered.
• Traverse the tag's descendants for more complex cases.

Parameters

string $content: The content, after applying inner transformations.

\Drupal\xbbcode\Parser\Tree\TagElementInterface $tag: The original tag element.

Return value

string The prepared output.

Overrides TagPluginBase::prepare
