PHP DomDocument results empty
tag without closing tag

Question

I have a html code that contains:

<ul>
    <li></li>
    <li></li>
    <li></li>
</ul>

after parsing it using php DOMDocument and using saveHTML function of it, the result is:

<ul>
    <li>
    <li>
    <li>
</ul>

this only happens with <li> tags. how to force the output to include closing tag for <li> tags?

I tried to solve with regex but couldn't find a solution. If you have a regex solution I accept it too.

@Quentin I know but prefer to have the end tag. without it looks buggy to me. — user1447420, Oct 29 '17 at 21:43
The behavior appears to be dependent on having content or not with another `li` element proceeding it. — Scuzzy, Oct 29 '17 at 21:54
@Scuzzy This is ***not*** a duplicate. That question is about HTML. This question is about PHP's implementation of DOMDocument. (Shoes are not a duplicate of socks, even though they are both worn on the feet.) — Jake, May 19 '18 at 22:43
@Jake `An li element's end tag may be omitted if the li element is immediately followed by another li element or if there is no more content in the parent element.` Also, this was closed October of 2017 — Scuzzy, May 20 '18 at 00:12

As per Does the <li> tag in HTML have an ending tag?

An li element's end tag may be omitted if the li element is immediately followed by another li element or if there is no more content in the parent element.

$html = '
<html>
  <body>
  <ul>
    <li></li>
    <li>foo</li>
    <li></li>
    <li></li>
    </ul>
  </body>
</html>
';
$doc = new DOMDocument;
$doc->loadHTML($html);
echo $doc->saveHTML();

Prints

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html><body>
  <ul><li>
    <li>foo</li>
    <li>
    <li>
    </ul></body></html>

Thank you for the answer. I know it is optional. Buy my prefer is to have it. — user1447420, Oct 29 '17 at 22:00
