Yahoo Pipes RSS Question

I’m using Yahoo Pipes to create some mashup RSS feeds, and then using fetch_rss to bring the Yahoo Pipe RSS into wordpress. I am able to easily show the post title, but I also want to show the post author. To show the title I’m using the following code:

echo wp_specialchars(substr($item2['title'],0,80)) . "...";

this works great. Yahoo pipes stores the author under dc.creator. How do I reference that in the RSS feed. I’ve tried this, but it doesn’t work.

echo wp_specialchars($item2['dc']['creator']);

Thoughts

The full code looks this, and it was created by the nice people at devlougne.

<?php
					require_once (ABSPATH . WPINC . '/rss-functions.php');
					// insert the feed URL here
					// insert the feed URL here
					$rss2 = @fetch_rss('http://pipes.yahoo.com/pipes/pipe.run?_id=b5163d43fb4b70e424ee593c29b01ea0&_render=rss');
					if ( isset($rss2->items) && 0 != count($rss2->items) ) {
				?>
				<?php
					// set the number of items from the feed to display (10)
					$rss2->items = array_slice($rss2->items, 0, 10);
					foreach ($rss2->items as $item2 ) {
				?>
				<ul>
				<li>
					<a href='<?php echo wp_filter_kses($item2['link']); ?>'>

					<?php
						if (strlen($item2['title']) > 80)
							echo wp_specialchars(substr($item2['title'],0,80)) . "...";
						else
							echo wp_specialchars($item2['title']);
					?>
					<br />
					<span class="cfroundmoreinfo"><?php echo wp_specialchars($item2['dc']['creator']); ?></span></a></li>
				</ul>
				<?php } ?>
				<?php } ?>
