Php simplexml 添加节点


原始代码如下


//================
<?
//创建xml对象
$xml = new SimpleXMLElement('<Messages></Messages>');
   
   
for($i=0;$i<10;$i++)
{
$xml->message[$i] = ''; //新节点
$xml->message[$i]['id'] = "id".$i;
$xml->message[$i]->title = "title".$i;
$xml->message[$i]->content = "content".$i;
$xml->message[$i]->time = "time".$i; //根据消息id 查询它相关的回复信息
 }

$xml->message2[0] = "";
$xml->message2[0]->title1="this is new att";

//$xml->asXML('messages.xml');
//直接输出成xml内容
echo $xml->asXML();;

?>
//===========================


也就是说如果要添加新的节点，不需要执行任何函数，直接用
$xml->message2[0] = "";就可以得到新的节点。

 

同样，添加新的属性也是不需要任何函数，直接用新的成员。

比如

$xml->message2[0]->title1="this is new att";
