IIRC (I haven't used PHP in a while), the SAX module for PHP passes a
dictionary containing the attribute name/value pairs to the element
start handler function, so you *can* access the attribute quite easily. 

... the PHP docs at http://www.php.net/manual/en/ref.xml.php confirm
this, here's an example element start handler function: 

function startElement($parser, $name, $attrs) { 
   /* $parser is a handler to the parser instance, 
      $name is the name of the element started 
      $attrs is a dictionary (associative array) with attribute values 

You do need to register your element handler functions with
xml_set_element_handler() first, of course.
