 $doc->load( 'books.xml' );
 $books = $doc->getElementsByTagName( "book" );
 foreach( $books as $book )
 {
 $authors = $book->getElementsByTagName( "author" );
 $author = $authors->item(0)->nodeValue;
 $publishers = $book->getElementsByTagName( "publisher" );
 $publisher = $publishers->item(0)->nodeValue;
 $titles = $book->getElementsByTagName( "title" );
 $title = $titles->item(0)->nodeValue;
 echo "$title - $author - $publisher\n";
 }
?>
