function RSS_Links($url, $size)
{
global $RSS_Content;

$page = "

";

RSS_RetrieveLinks($url);
if($size > 0)
$recents = array_slice($RSS_Content, 0, $size);

foreach($recents as $article)
{
$type = $article["type"];
if($type == 0) continue;
$title = $article["title"];
$link = $article["link"];
$page .= "

$page .="

\n";

return $page;

global $RSS_Content;

$opened = false;
$page = "";

RSS_Retrieve($url);
if($size > 0)
$recents = array_slice($RSS_Content, 0, $size);

foreach($recents as $article)
{
$type = $article["type"];
if($type == 0)
{
if($opened == true)
{
$page .="\n";
$opened = false;
}
$page .="";
}
else
{
if($opened == false)
{
$page .= "

\n";
$opened = true;
}
}
$title = $article["title"];
$link = $article["link"];
$description = $article["description"];
$page .= "
• $title";

if($description != false)
{
$page .= "
$description";
}
$page .= "\n";

if($type==0)
{
$page .="
";
