If you use saveXML instead of saveHTML, it will self-close empty tags. 
Then for any tags that should not be self-closed, you just need to pass 
an empty value as the second parameter of createElement.

$doc->createElement('source');
...
echo $doc->saveXML(); // <source />

$doc->createElement('div', '');
...
echo $doc->saveXML(); // <div></div>

That's the way I'd do it. Hope that helps.
