   Example

   To create a custom feed that takes a GET parameter on a URL (e.g. http://www.example.com/?feed=myfeed&type=excerpt), place something like the following in your particular feed file to send an excerpt (the_excerpt_rss()) instead of the full content (the_content()):

   
   if isset( $_GET['type'] ) ) {
   	$typewanted = sanitize_text_field( $_GET['type'] );
   }
   
   if ( $typewantd == 'excerpt' ) {
   	// Wrap the Excerpt in a span tag for CSS styling
   	echo '<span class="excerpt">'; 
   		the_excerpt_rss();   
   	echo '</span>';
   } else {  
   	// Otherwise they want the full content so wrap it in another span
   	echo '<span class="content">';
   		the_content();
   	echo '</span>';
   }
