如何获得媒体：内容使用SimpleXML(How to get media:content with

我有一个XML饲料，我可以获取有关新闻网站塞浦路斯新闻。我想用新闻图片当然新闻本身。

下面是XML的一种样品

 <item>
      <title>Rumlardan KKTC üniversitelerine ambargo</title>
      <description>

的XML的链接是： http://www.ntvmsnbc.com/id/24928068/device/rss/rss.xml

现在我解析这个XML使用SimpleXML使用下面的代码。在此代码我可以防止显示<img>与strip_标签我只能在CDATA显示文本数据标签。

总之我是问我如何能得到media:content url=""到我的代码，因为我想改变thumb.jpg到hlarge.jpg在该网址。

我试图$d['media'] = $news->media->attributes(); '<p>'.$post['media']['url']. 但它不工作

这里是我的代码：

<? 
$NewsFeedUrl =  "http://www.ntvmsnbc.com/id/24928068/device/rss/rss.xml";

$xml = @simplexml_load_file($NewsFeedUrl);

if(is_object($xml)){
    //Rest of our code will be here
}else{
    die('Güncel Haberlere Bağlanılamıyor.');
}

foreach($xml->channel->item as $news){
    if(is_array($newsContent) && count($newsContent)==$amountToShow){
    }
    $description = $news->description;
    $d['title'] =$news->title;
    $d['link'] = $news->link;
    $d['media'] = $news->media->attributes();
    $d['cont'] = $news->description;
    $d['date'] = $news->pubDate;
    $newsContent[]=$d;
}
//$ad=array("thumb", "left");

if(is_array($newsContent)){
    foreach($newsContent as $post){

        echo '

      <article class="entry"><h3>'.'<a href="'.$post['link'].' "target="_blank">'.$post['title'].'</a></h3>
      '.'<div class="meta"><span class="date_post">'.$post['date'].'</span>'.$post['pubDate'].
      //'<p>'.str_replace($ad,"hlarge",$post['cont']).
      '<p>'.$post['cont'].
      '<p>'.strip_tags($post['cont']).
      //'<p>'.$post['media']['url'].
      '<p><a href="'.$post['link'].' "target="_blank" class="button">Devamını Oku</a>'.
      ' </article>';
    }
}else{
    echo '<p>Güncel Haberler Alınamadı Sayfayı Yenilemeyi Deneyin.</p>';
}

?>

所述content元素有一个命名空间前缀（ <media:content> ），所以它不能由通常的方法进行访问。

命名空间URI为“媒体”是从http://search.yahoo.com/mrss/ （检查rss.xml为“的xmlns：媒体”）。

试试这个：

foreach ($xml->channel->item as $news)
{
    $ns_media = $news->children('http://search.yahoo.com/mrss/');

    echo $ns_media->content; // displays "<media:content>"
}

编辑：

我认为有一些概率与空间URI“ http://search.yahoo.com/mrss/ ”

我试着用你的 XML：

我尝试使用其他 XML：
