This plugins allows HTML comments to be used. Internet Explorer's conditional comments are explicitly disabled because they could pose a security risk as they could be used to bypass the built-in template security.
The characters <
or >
are removed from the comments' contents, as well as the illegal sequence --
.
Example
$configurator = new s9e\TextFormatter\Configurator;
$configurator->plugins->load('HTMLComments');
// Get an instance of the parser and the renderer
extract($configurator->finalize());
$text = '<!-- comment -->';
$xml = $parser->parse($text);
$html = $renderer->render($xml);
echo $html;
<!-- comment -->
