Preventing DOMDocument from stripping white spaces after empty tags
I know this is an old issue, and I was looking for the same thing when I came across this https://bugs.php.net/bug.php?id=50278
In the notes it says to pass LIBXML_HTML_NODEFDTD as an option like this:
$doc = new DOMDocument();$doc->loadHTMLFile($file, LIBXML_HTML_NODEFDTD);echo $doc->saveHTML();This will keep the white space.
