                        <div class="grid_6">

                            echo '</li>
                    ';
                }

            echo '</ul>
        ';

The error that im getting is

$items = array ('title' => $node->getElementsByTagName('title')->item(0)->nodeValue,'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,'description' => $node->getElementsByTagName('description')->item(0)->nodeValue,'pubDate' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue);

Answer 1

What version of PHP are you using?

Older versions (PHP 4.x) do not allow chaining of object method calls.

Not allowed:

$node->getElementsByTagName('pubDate')->item(0)->nodeValue

Allowed:

$temp = $node->getElementsByTagName('pubDate');
$temp = $temp->item(0);
$temp = $temp->nodeValue;

UPDATE

To translate your problem line into PHP4:

$items = array(
    'title'       => get_tag_value($node, 'title'),
    'link'        => get_tag_value($node, 'link'),
    'description' => get_tag_value($node, 'description'),
    'pubDate'     => get_tag_value($node, 'pubDate'),
);

And then add this function somewhere in your code:

function get_tag_value($node, $tag){
    $tags = $node->getElementsByTagName($tag);
    $tag = $tags->item(0);
    return $tag->nodeValue;
}
