Using shortcode to stop post content from displaying

Instead of use of shortcode, you can get the post content, format them the way you want and display them later.

You can use get_the_content function; which will just retrieve post content in a variable.

    $raw_input = get_the_content();
/*process your content here and store the result in variable
eg.*/ 
$raw_input = str_replace("No", "Yes", $raw_input);
print $raw_input;

This will print the processed content and you can just comment out the_content() function in your single.php.
