Обмен HTML в для AMP страниц

Я нашел решение для переключения шорткодов:

// AMP change thrive-shortcode to landingpage link
function add_shortcode_amp($content) {
if (function_exists( 'is_amp_endpoint' ) && is_amp_endpoint()) {
/// Define shortcode-name
$mb_shortc = 'thrive_2step';
/// Define Mappings (thrive_2step id => Target URL for links in AMP)
$ampMappings = array(
"17503" => 'https://www.test.de/schreibtisch-workout-2',
"17505" => 'https://www.test.de/merkmale-arbeitsplatz-kostenlos',
"17506" => 'https://www.test.de/hoehenverstellbarer-schreibtisch-rentenverischerung-antrag');

/// Init Regex arrays
$mb_rexp =  array();
$subst = array();
foreach ($ampMappings as $key => $value) {
$mb_rexp[] = '/\[('.$mb_shortc.').*?.id=[\'"]'.$key.'[\'"].*?\](.*?)\[\/\1\]?/';
$subst[] = '<a href="'.$value.'">${2}</a>';
}
/// Process Content
return preg_replace($mb_rexp, $subst, $content);
}
return $content;
}
add_filter( 'the_content', 'add_shortcode_amp', 6);

function mbtest_hello_world() {
return '<a>Hello World</a>';
}
add_shortcode('AMPTEST', 'mbtest_hello_world');

function shortcode_switch4amp( $atts) {
extract( shortcode_atts( array(
'regular' => 'regular',
'amp' => 'amp'
), $atts ) );
if (function_exists( 'is_amp_endpoint' ) && is_amp_endpoint()) {
return do_shortcode(str_replace(array("{","}"), array("[","]"),$amp));
} else {
return do_shortcode(str_replace(array("{","}"), array("[","]"), $regular));
}
}
add_shortcode('switch4amp', 'shortcode_switch4amp');
