		$data=$xml->xpath("//book/@msg");
Copy after login

上面一段code会输出如下内容
array(1) { [0]=> object(SimpleXMLElement)#9 (1) { ["@attributes"]=> array(1) { ["msg"]=> string(24) "小王子" } } }
请问如何让它只返回msg里边的内容,而不返回数据路径"@attributes


回复讨论(解决方案)


$data=$xml->xpath("//book/@msg");$str = (string)$data[0];
Copy after login
