如何获取媒体:SimpleXML的内容 [英] How to get media:content with SimpleXML

问题描述

我有一个XML feed，可以在新闻站点上获取有关塞浦路斯的新闻. 我想使用新闻图片，当然也要使用新闻本身.

I have an XML feed that i could fetch news about cyprus on a news site. I want to use news images and of course news itself.

这是xml的示例

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

          Kıbrıs Rum yönetimi, KKTC'deki üniversitelerle işbirliği yapan ülkelerin eğitim kurumlarına resmi yazılar göndererek yetkilileri tehdit ediyor. Hindistan üniversitesinden ortak akademik programlara son verilmesi istendi.</p><br clear="all" />]]>

        </media:text>
      </media:content>

      <category>Haberler</category>

    </item>

xml的链接为: http://www.ntvmsnbc .com/id/24928068/device/rss/rss.xml

现在，我使用以下代码使用simpleXML解析此xml.在此代码上，我可以防止显示带有strip_标签的<img>标签，而我只能在CDATA中显示文本数据.

Now i parse this xml with simpleXML with using below code. On this code i could prevent to display <img> tag with strip_ tags i could only display text data in CDATA.

简而言之，我要问的是如何将media:content url=""插入代码中，因为我想在该URL中将thumb.jpg更改为hlarge.jpg.

In short what i am asking is how can i get media:content url="" into my code as I want to change thumb.jpg to hlarge.jpg in that url .

我尝试了$d['media'] = $news->media->attributes(); '<p>'.$post['media']['url'].，但是它不起作用

I tried $d['media'] = $news->media->attributes(); '<p>'.$post['media']['url']. but it's not working

这是我的代码:

<? 
$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>';
}

?>

推荐答案

content元素具有名称空间前缀(<media:content>)，因此无法通过通常的方式进行访问.

The content element has a namespace prefix (<media:content>), so it can’t be accessed by the usual means.

媒体"的命名空间URI来自http://search.yahoo.com/mrss/(请在rss.xml中检查"xmlns:media").

Namespace-URI for "media" is from http://search.yahoo.com/mrss/ (check your rss.xml for "xmlns:media").

尝试一下:

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

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

我认为存在名称空间uri" http://search.yahoo.com/mrss/"

I think there is some prob with the namespace uri "http://search.yahoo.com/mrss/"

我尝试使用您的 xml:

http://codepad.org/P90bOQUj [不起作用]

我尝试使用 other xml:

http://codepad.org/ADYveL6T [有效]
