I am not to good with reading file contents using PHP, so instead of spending hours on the web, I found a site that provides code for an RSS reader in PHP and I am having some trouble with it.

The site is located here (this page includes the coding anyway):
http://www.sitepoint.com/examples/ph...tcover.php.txt


The page I am trying to get the RSS feeds from is here:
http://www.gamebattles.com/xbox360/h...ANCE/stats.xml

Gamebattles provides detailed stats to the raw bone on their site now, but I don't know how to retrieve them... should I even use this script or can I write something simple?
First off, I am trying to get JUST the names of all the players, I modified the coding provided by the site to try to get it to work based on the RSS tags, but no hope. Heres the code:
PHP Code:
<?php

$insideitem 
false;
$tag "";
$name "";

function 
startElement($parser$name$attrs) {
    global 
$insideitem$tag$name;
    if (
$insideitem) {
        
$tag $name;
    } elseif (
$name == "PLAYER") {
        
$insideitem true;
    }
}

function 
endElement($parser$name) {
    global 
$insideitem$tag$name;
    if (
$name == "PLAYER") {
        
printf("<dt><b><a href='%s'>%s</a></b></dt>",
            
trim($link),htmlspecialchars(trim($name)));
        
printf("<dd>%s</dd>",htmlspecialchars(trim($description)));
        
$name "";
        
$insideitem false;
    }
}

function 
characterData($parser$data) {
    global 
$insideitem$tag$name;
    if (
$insideitem) {
    switch (
$tag) {
        case 
"NAME":
        
$name .= $data;
        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.gamebattles.com/xbox360/halo3/team/PERFECTALLIANCE/stats.xml","r")
    or die(
"Error reading RSS data.");
while (
$data fread($fp4096))
    
xml_parse($xml_parser$datafeof($fp))
        or die(
sprintf("XML error: %s at line %d",
            
xml_error_string(xml_get_error_code($xml_parser)),
            
xml_get_current_line_number($xml_parser)));
fclose($fp);
xml_parser_free($xml_parser);

?>
Beyond this (if I can get this to work), I would also like to figure out how to retrieve the matches and stuff, but it's very confusing for me. I am good with PHP, but I have trouble when it comes to things like this, it doesn't make sense to me how its setting everything first and then it reads the file at the end.
I try the script out, and it doesn't display anything. It's not getting the results from the news feed. I don't know what else to do. Is there a simple fix or am I missing something that will make it run?
If someone could help me with this, I would really appreciate it and so would the gamers on the clan site I am using this one for!
