XML_Unserializer - is it right?

//The XML_Unserializer does not create the same dataType for //the follow two xml. $xml = "<root id='12'> <child name='john' age='23'/> <child name='paul' age='24'/> </root>"; $xml2 = "<root id='12'> <child name='john' age='23'/> </root>"; // the only difference between $xml and $xml2 is that the second has only 1 child require_once 'XML/Unserializer.php'; $options = array('complexType'=>'array', 'parseAttributes'=>true); $tree = & new XML_Unserializer($options); $tree->unserialize($xml); $data = $tree->getUnserializedData(); foreach($data['child'] as $child): var_dump($child); // the data type is not the same for $xml and $xml2 endforeach; // It means that I have always two situations: // 1 - when I have only 1 child // 2 - when I have 2 or more // I don't want to resolve it putting IF every time I have to iterate over a child // is it a bug, or I'm missing something
