Remove elements with only a   space using jQuery

WordPress does this thing with adding <p>&nbsp;</p> when doing a line-break in the backend.

I wonder if it is possible to select those p‘s somehow with jquery.

I guess empty() wouldn’t work since it isn’t really empty but contains a  . But contains() wouldn’t probably work either since a lot of other paragraphs also contain a space, right?

I only want to select those paragpahs that have only this ” ” inside.

UPDATE

I should have mentioned that I don’t want to remove the ps but add a class to it.

Answer 1

Add this to your functions.php file if you have access to the theme files.

function user_content_replace($content) {
    return str_replace('<p>&nbsp;</p>','<p class="example">&nbsp;</p>',$content);
}
add_filter('the_content','user_content_replace', 99);

I made it insert a class instead of removing.
