Bug description:XMLReader cannot store values in arrays

Description:
------------
I have tried every way possible to store the values from an XML sheet using
XMLReader in an array. The XML sheet is valid. I have tried this on two
systems now, both with the same problem. Colleagues cannot find anything
wrong either. Example code is below:

CODE:

$reader = new XMLReader();
$url = 'http://xml.com/info.php'; // not a
real URL
	
$reader->open($url);
	
$i = 0;
$j = 0;
	
while ($reader->read())
{
	if ($reader->nodeType == XMLReader::ELEMENT)
	{
		$attr[$i] = $reader->getAttribute("name"); // does not store anything
                $attr .= $reader->getAttribute("name"); // stores
perfectly
                i++;
	}
	if ($reader->nodeType == XMLReader::TEXT)
	{
		$val[$j] = $reader->value; // performs the same as above
		$val .= $reader->value;
		$j++;
	}
}

Test script:
---------------
$reader = new XMLReader();
$url = 'http://xml.com/info.php'; // insert a
real URL to test
	
$reader->open($url);
	
$i = 0;
	
while ($reader->read())
{	
        if ($reader->nodeType == XMLReader::TEXT)
	{
		$val[$i] = $reader->value; // does not work
		//$val .= $reader->value; // for demonstration only, works properly
		$i++;
	}
}

print_r($val);

Expected result:
----------------
When using a valid URL and XML sheet, "print_r" should print an array of
all values stored.

Actual result:
--------------
Instead, the entire array is empty. As soon as you use .= instead of
storing in an array, everything is printed fine simply using "echo".
