$file = "http://www.forosdelweb.com/external.php?type=RSS2";
$rss_channel = array();
$currently_writing = "";
$main = "";
$item_counter = 0;
function startElement($parser, $name, $attrs) {
global $rss_channel, $currently_writing, $main;
switch($name) {
case "RSS":
case "RDF:RDF":
case "ITEMS":
$currently_writing = "";
break;

$main = "CHANNEL";
break;
case "IMAGE":
$main = "IMAGE";
$rss_channel["IMAGE"] = array();
break;
case "ITEM":

default:
$currently_writing = $name;
break;
}
}
function endElement($parser, $name) {
global $rss_channel, $currently_writing, $item_counter;
$currently_writing = "";
if ($name == "ITEM") {
$item_counter++;
}
}
function characterData($parser, $data) {
global $rss_channel, $currently_writing, $main, $item_counter;
if ($currently_writing != "") {
switch($main) {
case "CHANNEL":
if (isset($rss_channel[$currently_writing])) {
$rss_channel[$currently_writing] .= $data;
} else {
$rss_channel[$currently_writing] = $data;
}
break;
case "IMAGE":
if (isset($rss_channel[$main][$currently_writing])) {
$rss_channel[$main][$currently_writing] .= $data;

$xml_parser = xml_parser_create();

xml_parser_free($xml_parser);
// sale en formato html
if (isset($rss_channel["ITEMS"])) {
if (count($rss_channel["ITEMS"]) > 0) {
// contador de cuantas noticias quires que se vea en html - cambiar la variable i
for($i = 0;$i < 2;$i++) {
if (isset($rss_channel["ITEMS"][$i]["LINK"])) {
// fecha de publicación
print ("<div>". utf8_decode($rss_channel["ITEMS"][$i]["PUBDATE"]) . "</div>");
// titulo con link a la noticia
print ("<a href='".utf8_decode($rss_channel["ITEMS"][$i]["LINK"])."'>". utf8_decode($rss_channel["ITEMS"][$i]["TITLE"]) . "</a>");
