DOMNamedNodeMap::item — Retrieves a node specified by index
Retrieves a node specified by index within the DOMNamedNodeMap object.
Index into this map.
The node at the indexth position in the map, or NULL if that is not a valid index (greater than or equal to the number of nodes in this map).
Nevermind: I got it, and here it is:
<?php
if($element->hasAttributes())
{
    $attributes = $element->attributes;
    if(!is_null($attributes))
    {
        foreach ($attributes as $index=>$attr)
        {
            echo $attr->name."=\"".$attr->value."\"";
        }
    }
}
?>
