Rss Php And Enclosure Problem

Dear friends,
im trying to create a parser in php to add in my site some infos from an rss feed the below:

http://www.yikers.com/rss/rss.xml

i want to input links, titles, descriptions, image. The general form of the feed is like the below:

<title>Guy Ends Fight By Punching Girl</title>
<link>http://www.yikers.com/video_guy_ends_fight_by_punching_girl.html</link>
<guid>http://www.yikers.com/video_guy_ends_fight_by_punching_girl.html</guid>

<description>He got praised for that? She should have took a spiked bat to his sac.</description>
<enclosure url="http://liveu-64.vo.llnwd.net/yikers/flv/thumbs/yikers_guy_ends_fight_by_punching_girl_3.jpg" type="image/jpeg" length="10000"/>
</item>

The problem is that the image is in an enlosure weird tag. I dont understand very well the whole rss-parsing thing so ive found the below php code that is able to provide me with all the infos except from the image cause it is in that enclosure tag. I give the code below:

$MAXLINKCOUNT = 100; // (* 2) if =10, 5 news items will show
$MAX_DESC_CHARS = 120;

$insideitem = false;
$tag = "";
$title = "";
$description = "";
$link = "";
$linkcount = 0;

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, $linkcount, $MAXLINKCOUNT, $MAX_DESC_CHARS;
if ($name == "ITEM" && $linkcount <= $MAXLINKCOUNT) {
if (strlen($description) > $MAX_DESC_CHARS) {
$description = wordwrap($description, $MAX_DESC_CHARS, "-=CUT OFF HERE=-");
$pos = strpos($description, "-=CUT OFF HERE=-");
$description = trim(substr($description, 0, $pos)) . "...";
}
$description = htmlspecialchars(trim($description));
$description = str_replace("&amp;quot;", "&quot;", $description);
printf("<dt><b><a href='%s'>%s</a></b></dt>", trim($link),htmlspecialchars(trim($title)));
printf("<dt>%s</dt><br>",$description);
$title = "";
$description = "";
$link = "";
$insideitem = false;
}
}

function characterData($parser, $data) {
global $insideitem, $tag, $title, $description, $link, $linkcount;
if ($insideitem) {
switch ($tag) {
case "TITLE":
$title .= $data;
break;
case "DESCRIPTION":
$description .= $data;
break;
case "LINK":
$link .= $data;
$linkcount++;
break;
}
}
}
$xml_parser = xml_parser_create();
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");
$fp = fopen("http://www.yikers.com/rss/rss.xml","r")
or die("Error reading RSS data.");
while ($data = fread($fp, 2048)) {
xml_parse($xml_parser, $data, feof($fp));
}
fclose($fp);
xml_parser_free($xml_parser);


can anyone provide me with the changes that i should do in order to get the image???
Thanks in advance!
