Hi all,

How do i use this script ?

<?php
class GamerCard
{
    var $memberType;

    var $tag;
    var $rep;
    var $score;
    var $zone;

    var $recentlyPlayed;

    var $gamerPictureUrl;


}

function error_handler($errno, $errstr)
{
}

function getGamerCard($gamerTag)
{
    $url = "http://gamercard.xbox.com/" . urlencode($gamerTag) . ".card";
    // Grab the gamercard - the card HTML is not valid xml (the base tag is not closed) 
    // but the "body" tag and its contents are a valid xml doc so we throw away the contents of the "head" tag. 
    // We don't need them anyway.
    
//    $request = new HTTPRequest($url);
//    $cardHTML = $request->DownloadToString();
    set_error_handler("error_handler");
    $cardHTML = file_get_contents($url);
    restore_error_handler();
    if ($cardHTML == false)
    {
        return "";
    }
    $tmp = preg_split("/<\/head>/", $cardHTML);
    $tmp = preg_split("/<\/html>/", $tmp[1]);
    $cardHTML = preg_replace(array("@<script[^>]*?>.*?</script>@si", "@<noscript[^>]*?>.*?</noscript>@si"), array("", ""), $tmp[0]); // Strip SCRIPT tags - not valid XML


    $xml = domxml_open_mem("<?xml version='1.0' standalone='yes'?>" . $cardHTML);
    if (!$xml)
    {
        print "Error parsing XML";
        exit;
    }

    $root = $xml->document_element();
    $xpath = $xml->xpath_new_context();

    $card = new GamerCard();
    $card->tag = $gamerTag;

// Membership type (Gold/Silver)

    $elems = $xml->get_elements_by_tagname("h3");
    foreach($elems as $elem)
    {
        $class = $elem->get_attribute("class");

        if ($class == "XbcGamertagGold")
            $card->memberType = "Gold";
        else if ($class == "XbcGamertagSilver")
            $card->memberType = "Silver";
    }

// Gamer picture
    $obj = $xpath->xpath_eval('//img[@class="XbcgcGamertile"]');
    $nodeset = $obj->nodeset;

    $card->gamerPictureUrl = $nodeset[0]->get_attribute("src");

// Gamerscore

    $obj = $xpath->xpath_eval('//span[preceding-sibling::span/img[@alt="Gamerscore"]]');
    $nodeset = $obj->nodeset;
    $card->score = $nodeset[0]->get_content();

// Rep

    $obj = $xpath->xpath_eval('//span[preceding-sibling::span="Rep"]/img');
    $nodeset = $obj->nodeset;

    $url = $nodeset[0]->get_attribute("src");
    $tmp = preg_split("/[._]/", $url);
    $card->rep = $tmp[3];

// Zone

    $obj = $xpath->xpath_eval('//span[preceding-sibling::span="Zone"]');
    $nodeset = $obj->nodeset;
    $card->zone = $nodeset[0]->get_content();

// Recently Played

    $obj = $xpath->xpath_eval('//div[@class="XbcgcGames"]//img');
    $nodeset = $obj->nodeset;
    
    foreach($nodeset as $node)
    {
        $card->recentlyPlayed[] = $node->get_attribute("title");
    }

    return $card;
}

?>

Thanks
