 Hi guys.

 I'm the author of the plugin WP Sitemaps Config
 [https://wordpress.org/plugins/wp-sitemaps-config/]. One of the features
 is to explude pages and posts from the sitemap. To achieve this I use the
 filter `wp_sitemaps_posts_entry`
 The `apply_filters()` function is located in `class-wp-sitemaps-posts.php`
 at line 140.

 When a user decides to explude a page or post, I do return `array( 'loc'
 => '' )` for this url. Unfortunatley this produces an empty line with
 `<url><loc/></url>` in the sitemap.
 Google gives an error when reading this sitemap.
 {{{
 Sitemap can be read, but has errors
 Invalid URL
 }}}
 To prevent this, the code in `class-wp-sitemaps-posts.php` at line 141
 should be changed in
 {{{#!php
 if( !empty( $sitemap_entry[ 'loc' ] ) ) {
   $url_list[]    = $sitemap_entry;
 }
 }}}
 This would prevent a blank line if the URL is removed by the filter.
