namespace error : Namespace prefix actor on view is not defined in /home/sweb/www/tmp/sxml.php on line 35

Answer 1

XML parsers rely on the fact documents have to be strictly valid, and yours is not well-formed. It needs a namespace URI for actor. The root element should be along the lines of this:

<movies xmlns:actor="http://yoururl.com/"&gt;

As long as you don't have it, no compliant XML parser will accept your document.

Thanks. It's OK but i have another problem. i can't access some elements look at this.

<?php
    $sxe = new SimpleXMLElement('http://rss.news.yahoo.com/rss/topstories', NULL, TRUE);

    var_dump((array) $sxe->channel->item);

see source of that rss. element media:content not access-able

also i use this method: $node->{'media:content'} but i cant parse that element?
