我有一个XML Feed,我可以在新闻网站上获取有关塞浦路斯的新闻。 我想使用新闻图片,当然还有新闻本身。
以下是xml的示例
<item>
<title>Rumlardan KKTC üniversitelerine ambargo</title>

xml的链接是:http://www.ntvmsnbc.com/id/24928068/device/rss/rss.xml
现在我用simpleXML解析这个xml并使用下面的代码。在此代码上,我可以阻止使用strip_标签显示<img>
标签,我只能在CDATA中显示文本数据。
简而言之,我要问的是如何将media:content url=""
放入我的代码中,因为我想将thumb.jpg更改为hlarge.jpg。
我尝试了$d['media'] = $news->media->attributes();
'<p>'.$post['media']['url'].
,但它无效
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="'.$post['link'].' "target="_blank" class="button">Devamını Oku</a>'.
' </article>';
}
}else{
echo '<p>Güncel Haberler Alınamadı Sayfayı Yenilemeyi Deneyin.</p>';
}
?>
答案 0 :(得分:3)
content
元素具有名称空间前缀(<media:content>
),因此无法通过常规方式访问它。
“媒体”的名称空间URI来自http://search.yahoo.com/mrss/
(请检查rss.xml
是否为“xmlns:media”)。
试试这个:
foreach ($xml->channel->item as $news)
{
$ns_media = $news->children('http://search.yahoo.com/mrss/');
echo $ns_media->content; // displays "<media:content>"
}
编辑:
我认为名称空间uri“http://search.yahoo.com/mrss/”
存在一些问题我尝试使用你的 xml:

我尝试使用其他 xml:

我也有这个问题,我使用以下解决方案进行了测试:
https://gist.github.com/enderandpeter/6b760140bf9d2ed9620c
成功了!
$content = $xml->channel->item->children('media', true)->content;
$contentattr = $content->attributes();
