Description:
------------
Hi,

I'm new to using the PHP DOM interface, so I apologize
if this "bug" is my misunderstanding of the specs, but
I haven't seen any mention of this anywhere yet.  I'm
using the get_elements_by_tagname

Reproduce code:
---------------
$dom = domxml_open_file("XMLBugTest.xml");
$temp = $dom->get_elements_by_tagname("x");
$y_nodes = $temp[0]->get_elements_by_tagname("y");

// Access the first node
$current_node = $y_nodes[0];

// Initialize the node counter
$nodecount = 0;

// Process each node in the collection
while($current_node)
{
	echo "<br>" . $current_node->node_type() . " -- " . $current_node->node_name() . " -- " . $current_node->get_content();
	
	// Count this node
	$nodecount++;
		
	// Get the next node in the collection
	$current_node = $current_node->next_sibling();
}

// Report the total node count
echo "<br>Number of processed nodes:  " . $nodecount;

Expected result:
----------------
1 -- y -- Item 1 
1 -- y -- Item 2 
1 -- y -- Item 3 
1 -- y -- Item 4 
Number of processed nodes: 4

Actual result:
--------------
1 -- y -- Item 1 
3 -- #text -- 
1 -- y -- Item 2 
3 -- #text -- 
1 -- y -- Item 3 
3 -- #text -- 
1 -- y -- Item 4 
3 -- #text -- 
Number of processed nodes: 8
