Twitter ATOM parsing issue with PHP + SimplePie

[Rollo_Tamasi]

Hi guys,
Last night I had my first play around with SimplePie (a feed aggregation script) and I decided to try out something with the Twitter Atom feed.

I am pulling entries from the ATOM feed and displaying them in a DIV on my own page. I have successfully managed to pull in Author, Link, Content and Date but I'm unable for some reason to pull in the Author Twitter. I'm not sure what I am doing wrong.

Does anyone have any ideas? Cheers.

<?php foreach ($feed->get_items() as $item): if ($author = $item->get_author()
if ($author_uri = $item->get_author_uri()) { } $feed = $item->get_feed(); ?>

<div class="item">
<h2><a href="<?php echo $item->get_permalink(); ?>"><?php echo
$item->get_title(); ?></a></h2>
<p>Author:<?php echo $author->get_name(); ?></p>
<p>Author Twitter: <?php echo $author_uri->get_author_uri(); ?></p>
<p>Link: <?php echo $item->get_link(); ?></p>
<p>Content: <?php echo $item->get_content(); ?></p>
<p>Posted on <?php echo $item->get_date('j F Y | g:i a'); ?></p>
</div>

<?php endforeach; ?>

This is an excerpt from the Twitter Atom feed for their search page

<p>Author Twitter: <?php echo $author_uri->get_author_uri(); ?></p>

sure that shouldn't be

<p>Author Twitter: <?php echo $author->get_uri(); ?></p>

Hi Dagon,
That's what I originally thought myself but for some reason that doesn't work.
