im using something like:

$span = $value -> find('span', 0);
var_dump($span);

and i get:

object(vokuhelperSimpleHtmlDomBlank)#63 (2) { ["node":protected]=> NULL ["classListCache":"vokuhelperAbstractSimpleHtmlDom":private]=> NULL }

next time used:

$ul = $value -> find('ul', 0);
var_dump($ul);

and i get just (I expect):

NULL

What’s the diffrent, where i made mistake?
I expect just NULL if, element don’t exist. Not object.
