I found some problems in QueryPath code：
In the line 463 to 470 of the file QueryPath.php :
If no match is found, we set an empty.
but the setting is not the outer of foreach!
In the line 484:
$vals = explode(' ', $nl->item($i)->getAttribute('class'));
$nl->item($i) is a DOMNode and there is no method getAttribute in class DOMNode.
In line 2973:
if ($lastDot !== FALSE && (strtolower(substr($filename, $lastDot)) == '.html'
but many file's extension are ".htm" and not ".html". What i can do?
In line 2788
$test = substr($string, 0, 255);
The variant $test is never used again from here.
