Netbeans DOMNodeList foreach hints are incorrect

I have been using NetBeans for some time. I have found it to be a very clean, powerful and elegant IDE for doing PHP web development, however doing a foreach around a DOMNodeList e.g. after a DOMXpath, produces incorrect syntax hints.

$booksDom = new DOMDocument();
$booksDom->load("/path/to/file.xml");
$xpath = new DOMXPath($booksDom);
$booksDOMNodeList = $xpath->query("//book]");
foreach ($booksDOMNodeList as $i => $bookDOMElement) {
    $bookDOMElement->|
}

If you try autocomplete on the "|" above, it produces autocomplete for $bookDOMElement as DOMNodeList, when $bookDOMElement is actually a DOMElement. However, there is another way to do the for the loop where Netbeans will autocomplete correctly for you.

$booksDom = new DOMDocument();
$booksDom->load("/path/to/file.xml");
$xpath = new DOMXPath($booksDom);
$booksDOMNodeList = $xpath->query("//book]");
for ($i = 0; $i < $booksDOMNodeList->length; $i++) {
    $bookDOMElement = $booksDOMNodeList->item($i);
    $bookDOMElement->|
}

The above example produces the code hints, that are correct, however adds another line. Note: I could have done $bookDOMElement = $booksDOMNodeList->item($i); in the first example's foreach loop, but I feel as if it does not look as neat.
