Sitemap adding Trailing Slashes to CPT’s they have been removed from via Hook

Hello,

Thank you for contacting Rank Math today.

We really appreciate the suggestion. I have forwarded this to the dev. team and we will see about the best method to handle this and incorporate it in a future update.

For now, you can use the following filter code to remove the trailing slash from the Posts URL:

add_filter( 'rank_math/sitemap/entry', function( $url, $type, $object ){
	if ( 'post' === $type ) {
		$url['loc'] = untrailingslashit( $url['loc'] );
	}

	return $url;
}, 10, 3 );

I hope that helps.

Hello

Thank you for contacting us again and sorry for the delay.
For now, our filter hooks can’t get a specific post type but like my colleague, we will forward this to the dev team so we can incorporate this in a future update.

But we think we might another solution for you. Here you can use this code. This code tested in our end.

/**
 * Filter if XML sitemap transient cache is enabled.
 *
 * @param boolean $unsigned Enable cache or not, defaults to true
 */
add_filter( 'rank_math/sitemap/entry', function( $url, $type, $object ){
	// This code will get the current xml url 
	$get_current_url="https://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
	$current_url = 'https://www.drugstrategies.org/treatment-center-sitemap1.xml';
	// This section will determine if the current xml url is equal to the current_url variable
	if ( $get_current_url === $current_url ) {
		$url['loc'] = untrailingslashit( $url['loc'] );
	}
	return $url;
}, 10, 3 );

Make sure you disable your XML cache after you put the code above or if you got any cache plugin clear it so you will see the changes on XML.

You can disable the Rank Math XML cache by adding this to your functions too.

/**
 * Filter if XML sitemap transient cache is enabled.
 *
 * @param boolean $unsigned Enable cache or not, defaults to true
 */
add_filter( 'rank_math/sitemap/enable_caching', '__return_false');

You can delete the Rank Math cache filter after you see the changes and you satisfy with the result.

Hope this solves your issue.
