I've implemented something similar. But it's not a smarty block. Instead I
use a template to display the
content. It works very well with the german Heise Newsticker
(http://www.heise.de/newsticker/heise.rdf).

Here's my function which returns the html content of the parsed template. It
should be easy to make a
block function of it.

function NewsFeed ($url) {
$template = new smartTemplate();
$news = Array();
$fcontents = join ('', file ($url));
$fcontents = str_replace("</item>", "", $fcontents);
$items = explode("<item>",$fcontents);
// Parse Channel Infos
ereg("<channel>(.*)</channel>",$items[0],$matches);
$channelBlock = $matches[1];
ereg("<title>(.*)</title>",$channelBlock,$matches);
$title = trim($matches[1]);
ereg("<link>(.*)</link>",$channelBlock,$matches);
$link = trim($matches[1]);
ereg("<description>(.*)</description>",$channelBlock,$matches);
$description = trim($matches[1]);
$channel = Array("title"=>$title,"link"=>$link,"description"=>$description);
// Parse News
unset($items[0]);
foreach ($items as $item) {
ereg("<title>(.*)</title>",$item,$matches);
$title = trim($matches[1]);
ereg("<link>(.*)</link>",$item,$matches);
$link = trim($matches[1]);
ereg("<description>(.*)</description>",$item,$matches);
$description = trim($matches[1]);
$news[] = Array("title"=>$title,"link"=>$link,"description"=>$description);
}
$template->assign("channel",$channel);
$template->assign("news",$news);
$content = $template->fetch("newsfeed.tpl");
return $content;
}

--------
{* TEMPLATE: newsfeed.tpl *}

{if (strval($channel.title) != "")}
{*
<div style="background-color:{$_API->theme->rowcolor1}; padding:2px;">
<b><a href="{$channel.link}" target="_blank">&gt;&gt;
{$channel.title}</a></b>
</div>
*}
<table cellspacing="0" cellpadding="0">
{section name="record" loop=$news}
<tr>
<td align="center" width="10" valign="top">
<b>&middot;</b>
</td>
<td valign="top">
<a href="{$news[record].link}"
target="_blank">{$news[record].title}</a><br/>
</td>
</tr>
{sectionelse}
No current news
{/section}
</table>
{else}
NewsFeed Block not configured correctly.
{/if}
