RSS feed displaying too many items

Hi

I have been using the following code to display RSS feeds on my sites for some time, but it is displaying 26 items, and I am concerned that this may be making the sites load slowly for some people.

Is there part of it that I can modify to limit the number of items that it displays? Any help would be appreciated.
Incidently, the code was initially provided by a member here but unfortunately I have lost their details.
Thanks
Tony

<?php
$insideitem = false;
$tag = "";
$title = "";
$description = "";
$link = "";
function startElement($parser, $name, $attrs) {
global $insideitem, $tag, $title, $description, $link;
if ($insideitem) {
$tag = $name;
} elseif ($name == "ITEM") {
$insideitem = true;
}
}
function endElement($parser, $name) {
global $insideitem, $tag, $title, $description, $link;
if ($name == "ITEM") {
printf("<dt><b><a href='%s'>%s</a></b></dt>",
trim($link),htmlspecialchars(trim($title)));
printf("<dt>%s</dt><br><br>",htmlspecialchars(trim($description)));
