解析媒体：来自RSS feed的内容与PHP

Question

I am trying to parse media:content from RSS with PHP and then show it using HTML.

I went through numerous posts on the same topic but since i'm a beginner I couldn't figure it out because the codes were different from mine.

Currently I dont' have any line that is trying to get the image from xml.

<?php
$html = "";
$url = "url.rss";

$xml = simplexml_load_file($url);
$namespaces = $xml->getNamespaces(true);

for($i = 0; $i < 50; $i++){
    $title = $xml->channel->item[$i]->title;
    $link = $xml->channel->item[$i]->link;
    $description = $xml->channel->item[$i]->description;
    $pubDate = $xml->channel->item[$i]->pubDate;
    $author = $xml->channel->item[$i]->author;


    $html .= "<a href='$link'><h3>$title</h3></a>";
    $html .= "$description";
    $html .= "<p>$pubDate</p>";
    $html .= "<p>$author</p><hr>";

}
echo $html;
?>

This is the info I need from the XML file:

 <media:content url="www.image.jpg" medium="image" type="image/jpeg"     width="850" height="425" />

Thanks!

I expect the PHP file to show the media file.

Answer 1

Can you please give us more info? What is the value of '$xml' after you run simplexml_load_file? (did you get the correct data?)

What error message did you get?

EDIT - according to your comment

try using

$xml->channel->item[$i]->children('media', true)->content->attributes();

The 'media' inside children is the namespace for the 'content' element. While the boolean 'true' variable tells the parser to refer the 'media' as a namespace
