simpleXML object里面不能读出数据怎么办？

class just{	function xmlInclude($data){		$xml = simplexml_load_file(dirname(__FILE__).'/jump.xml');		foreach($xml->Keyword->xpath("//*[data='$data']") as $item){		  return $item;		}	}}$TR = new just;$cr = $TR->xmlInclude(查询);print_r($cr);$cr=(array)$cr;echo '
';print_r($cr);

SimpleXMLElement Object ( [data] => 查询 [page] => Array ( [0] => dbcon.php [1] => select.php [2] => footer.php ) ) Array ( [data] => 查询 [page] => Array ( [0] => dbcon.php [1] => select.php [2] => footer.php ) )

echo $cr[0].$cr[0][0].$cr[1][0]
