Buying Need to programmer to help with parsing rss feed

I have an rss feed and it needs some changing. I have included the code below to give you a general idea.

1) I have an affiliate id on the links and it is currently wrong. It just needs modifying a bit.
2) I want some nofollows put in links and css classes put in as well.
3) Maybe also I want some links removing from the code.

<?PHP 
$feed = "http://rss.paddypower.com/rss/MoneyBackSpecial.xml";
$insideitem=""; $tag=""; $title=""; $description=""; $link=""; $AFF_ID=""; $max=""; $count="";  // needs to be done for all addtional feeds
$AFF_ID = "10001227";
$noresults = "Check back here soon for betting money back special offers.";
$max = 6; /* Number results outputted */ 
$count = 0; 



// Create an XML parser 
$xml_parser = xml_parser_create(); 

// Set the functions to handle opening and closing tags 
xml_set_element_handler($xml_parser, "startElement1", "endElement1"); // needs to be done for all addtional feeds

// Set the function to handle blocks of character data 
xml_set_character_data_handler($xml_parser, "characterData1"); // needs to be done for all addtional feeds

// Open the XML file for reading 
$fp = fopen($feed ,"r") or die("No feed available."); 

// Read the XML file 4KB at a time 
while ($data = fread($fp, 4096)) { 

// Parse each 4KB chunk with the XML parser created above 
xml_parse($xml_parser, $data, feof($fp)) 
// Handle errors in parsing 
or sprintf("XML error: %s at line %d", 
xml_error_string(xml_get_error_code($xml_parser)), 
xml_get_current_line_number($xml_parser)); 
} 

// Close the XML file 
fclose($fp); 

// Free up memory used by the XML parser 
xml_parser_free($xml_parser); 

if($count == 0) { 
echo $noresults; 
} 

function startElement1($parser, $name, $attrs) { // needs to be done for all addtional feeds
global $insideitem, $tag, $title, $description, $link; 
if ($insideitem) { 
$tag = $name; 
} elseif ($name == "ITEM") { 
$insideitem = true; 
} 
} 
function endElement1($parser, $name ) { // needs to be done for all addtional feeds
global $insideitem, $tag, $title, $description, $link, $AFF_ID, $max, $count; 
if ($name == "ITEM" && $count < $max ) { 
printf("<b><a href='%s' class=\"feed_title\" target=\"_blank\" rel=\"nofollow\">%s</a></b><br>", trim($link)."&AFF_ID=".$AFF_ID,htmlspecialchars(trim($title))); 
printf("%s<br><br>" , html_entity_decode(trim($description))); 
$title = ""; 
$description = ""; 
$link = "";
$insideitem = false; 
$count++; 
} 
} 

function characterData1($parser, $data) { // needs to be done for all addtional feeds
global $insideitem, $tag, $title, $description, $link,$AFF_ID; 
if ($insideitem) { 
switch ($tag) { 
case "TITLE": 
$title .= $data; 
break; 
case "DESCRIPTION":
//var_dump(strstr($data,".html"));
if(strstr($data,".html") !== false)
$data = str_replace(".html" , ".html?AFF_ID=".$AFF_ID , $data); 
$description .= $data; 
break; 
case "LINK": 
$link .= $data; 
break; 
} 
} 
} 

?>
