在php解析後訪問xml對象

Question

如果有人能解釋一下如何訪問這個xml feed的'item'部分。這是文件的VAR_DUMP。即時通訊使用simplexml_load_string拉從谷歌的飼料，但如何我可以訪問到「項」內容

object(SimpleXMLElement)[1] 
    public '@attributes' => 
    array 
     'version' => string '2.0' (length=3) 
    public 'channel' => 
    object(SimpleXMLElement)[2] 
     public 'generator' => string 'NFE/1.0' (length=7)

     public 'pubDate' => string 'Sun, 22 Jan 2012 04:38:34 GMT' (length=29) 
     public 'lastBuildDate' => string 'Sun, 22 Jan 2012 04:38:34 GMT' (length=29)

     public 'item' => 
     array 
      0 => 
      object(SimpleXMLElement)[4] 
       ... 
      1 => 
      object(SimpleXMLElement)[5] 
       ... 
      2 => 
      object(SimpleXMLElement)[6] 
       ... 
      3 =>

       ... 
      8 => 
      object(SimpleXMLElement)[12] 
       ...

      object(SimpleXMLElement)[13] 
       ...

Answer 1

看起來你可以訪問像這樣的「項目」的成員變量：$yourObject->channel->item

Answer 2

有你在你問之前試圖尋找？有很多教程如何解析RSS提要 - for example

foreach($yourObject->channel->item as $item) 
{ 
    echo $item->title; 
    echo $item->link; 
}
