Description
It's currently not possible to know if an element has children without getting notices when the input is an empty div:
$elem->children()->count();
(even when just doing $elem->children())

This is due to the call to the sibling function with:
$this->getNode(0)->firstChild
An empty div has no firstChild so in the sibling function this generates the notice above.
One could fix this by adding a function such as:
public function hasChildren()
{
if (!count($this) || !$this->getNode(0)->firstChild || (new static($this->sibling($this->getNode(0)->firstChild), $this->uri))->count() == 0) {
return false;
} else {
return true;
}
}
