I used the following code on one of my in-development sites, http://www.dnaguardian.com/index.php

<?php

class RSSParser {

var $insideitem = false;

var $tag = "";

var $title = "";

var $description = "";

var $link = "";

var $XML_parsed = '';

function startElement($parser, $tagName, $attrs) {

if ($this->insideitem) {

$this->tag = $tagName;

} elseif ($tagName == "ITEM") {

$this->insideitem = true;

}

}

function endElement($parser, $tagName) {

if ($tagName == "ITEM") {

//printf("<dt><b><a href='%s'>%s</a></b></dt>",

// trim($this->link),htmlspecial=chars(trim($this->title)));

//printf("<dd>%s</dd>",htmlspecialchars(trim($this->description)));

$this->XML_parsed .= html_entity_decode('<br /><br /><a target="_blank" href="'.trim($this->link).'"> '.htmlspecialchars(trim($this->title)).'</a><br />'.htmlspecialchars(trim($this->description)));

$this->title = "";

$this->description = "";

$this->link = "";

$this->insideitem = false;

}

}

function getParsedXML(){

return $this->XML_parsed;

}

function characterData($parser, $data) {

if ($this->insideitem) {

switch ($this->tag) {

case "TITLE":

$this->title .= $data;

break;

case "DESCRIPTION":

$this->description .= $data;

break;

case "LINK":

$this->link .= $data;

break;

}

}

}

}

switch($_POST['channel']){

case 'Current Amber Alerts':

$channel = 'http://www.teamamberalert.net/news/backend.php';

}

$xml_parser = xml_parser_create();

$rss_parser = new RSSParser();

xml_set_object($xml_parser,&$rss_parser);

xml_set_element_handler($xml_parser, "startElement", "endElement");

xml_set_character_data_handler($xml_parser, "characterData");

$fp = fopen($channel,"r")

or die("Error reading RSS data.");

while ($data = fread($fp, 4096))

xml_parse($xml_parser, $data, feof($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);

// Assign resulting parsed XML to a variable

$headlines = $rss_parser->getParsedXML();

$index->assign("CHANNEL_HEADLINES", $headlines);

xml_parser_free($xml_parser);

?>

As you can see there is a mod in there by me that allows a person to 'change the channel' to select a different feed. If you don't want this ability, feel free to comment out that code, otherwise you'll need to add a form field for the $_POST variable on whatever page you are placing the feed on.

If you'd like more explanation about how I implemented it on the page, please feel free to PM me.
