从DOM Document类获取根节点

I am trying to get the root node of a PHP DOM Document. This is usually done by doing something like this:

$doc->documentElement;

However, trying this on a HTML string that contains a doctype:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml">...

and that is loaded into a DOM Document object like so:

$doc = new DOMDocument();
$doc->loadHTML($html);

returns the root node as the html tag and not the doctype tag! I am guessing this because of the weird characters <!- is there anyway to return the root node correctly?

    Doctype isn't the root node, html is. The doctype is simply the doctype declaration that tells the browser what the rest of the file is.

    Maybe you can use DOMDocument::doctype ? ($doc -> doctype)
