Question

HI有人可以解释如何访问此xml提要的“项目”部分。这是文件的VAR_DUMP。我使用simplexml_load_string从google中提取Feed，但如何访问“item”内容

    object(SimpleXMLElement)[1]
  public '@attributes' => 
    array
      'version' => string '2.0' (length=3)
  public 'channel' =>

      public 'item' => 
        array
          0 => 
            object(SimpleXMLElement)[4]
              ...
          1 => 
            object(SimpleXMLElement)[5]
              ...
          2 => 
            object(SimpleXMLElement)[6]
              ...
          3 => 
            object(SimpleXMLElement)[7]
              ...
          4 => 
            object(SimpleXMLElement)[8]
              ...
          5 => 
            object(SimpleXMLElement)[9]
              ...
          6 => 
            object(SimpleXMLElement)[10]
              ...
          7 => 
            object(SimpleXMLElement)[11]
              ...
          8 => 
            object(SimpleXMLElement)[12]
              ...
          9 => 
            object(SimpleXMLElement)[13]
              ...
      public 'description' => string 'Google News' (length=11)

Answer 1

看起来你可以像这样访问'item'成员变量：$yourObject->channel->item

Answer 2

你问过之前有没有试过搜索？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;
}

php解析后访问xml对象
