How to remove elements with whitespace?

Question

I can easily remove a tag that has no blank spaces...

$(\'h2:empty\').remove();

But, when there is a space...

 &l         


        

Answer 1

I don't use jQuery, but I can give a straight JavaScript solution:

var elms = document.getElementsByTagName('h2'), l = elms.length, i;
for( i=l-1; i>=0; i--) {
    if( elms[i].innerHTML.replace(/\s+/,"") == "") {
        elms[i].parentNode.removeChild(elms[i]);
    }
}

So just do whatever the jQuery equivalent is, I guess.
