Ayuda para integrar XML con parser PHP

[wood]

Estoy muy verde en estos temas.
Necesito integrar el siguiente formato XML, para que aparezcan el title, Description y URL:

<Listings>
<Page></Page>
<Count></Count>
<Listing>
<Title></Title>
<URL></URL>
<URI></URI>
<Description></Description>
<Bid></Bid>

</Listing>
<Listing>
<Title></Title>
<URL></URL>
<URI></URI>
<Description> </Description>
<Bid></Bid>
</Listing>
...
</Listings>

Dispongo de este parser PHP, aunque pudiera ser otro:

Código:

<?php
/if ($current_category["pages"] == "y")
$search = "".$current_category["name"]; /* Term to be searched */
 


/* ---------- Ignore this part ---------- */
$_allow_ip = array( '*.*.*.*' );
$_ip = $_SERVER['REMOTE_ADDR'];

$file = "http://www.url.com/rd/feed/XMLFeed.jsp?trackID=xxxxxxx&pID=xxxxx&cat=&searchnl=5&page=1&ip=1.1.1.1&excID=";
$write = "true";
$numberofa = 0;
$maxa = 10;

/* Everything between the "" in this section will be printed BEFORE the result */
function startElement($parser, $name, $attrs) {
global $write;
global $numberofa;
global $maxa;
if ($numberofa < $maxa) {
   switch ($name) {
      case "TYPE":
	     print ""; /* So anything here would show up before the TYPE Result */
	  	 $write = "false"; 
      break;
      case "REDIRECT_URL":
	     print "<a href='"; 
	     $write = "true"; 
      break;
      case "SITE_URL":  
	     print "";
		   $write = "false"; 
      break;
      case "DOMAIN":
	     print "";
	     $write = "false"; 
      break;
      case "TITLE":
	     print "<b>";
	     $write = "true"; /* This will print the Title */
	     break;	
      case "DESCRIPTION":
	     print "";
	     $write = "true"; /* This will print the Description */
	     break;
			 case "LOGOLINK":
	     print "";
	     $write = "false";  /* This will print the logo (if any), however I have no work around for no logo yet */
	     break;
			 case "BID":
	     print "";
	     $write = "false";  /* This will print the bid price */
	     break;
			 case "NK":
	     print "";
	     $write = "false";  /* I forget what this is... */
	     break;
   }
}
}


/* Everything between the "" in this section will be printed AFTER the result */
function endElement($parser, $name) {
global $write;
global $numberofa;
global $maxa;
			
if ($numberofa < $maxa) {
  switch ($name) {
      case "TYPE":
	    print ""; /* So anything here would show up after the TYPE Result */
	  	 $write = "false";
 	     $numberofa++;
	  	 break;
      case "REDIRECT_URL":
	    print "'>";
	     $write = "true";
      break;
      case "SITE_URL":
	     print "";
		   $write = "false";
	     break;
      case "DOMAIN":
	     print "";
	     $write = "false";
	     break;
      case "TITLE":
	     print "</b></a><br>";
	     $write = "true";
	     break;	
      case "DESCRIPTION":
	     print "<br><br>";
	     $write = "true";
	     break;
			 case "LOGOLINK":
	     print "";
	     $write = "false";
	     break;
			 case "BID":
	     print "";
	     $write = "false";
	     break;
			 case "NK":
	     print "";
	     $write = "false";
	     break;
   }
}
}

/* ---------- Nothing to edit beyond this point ---------- */

function characterData($parser, $data) {
global $write;
if ($write == "true") {
   print $data;
}

}

$xml_parser = xml_parser_create();
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");
if (!($fp = fopen($file, "r"))) {
   die("No more data");
}
while ($data = fread($fp, 4096)) {
   if (!xml_parse($xml_parser, $data, feof($fp))) {
      die(sprintf("XML error: %s at line %d",
      xml_error_string(xml_get_error_code($xml_parser)),
      xml_get_current_line_number($xml_parser)));
   }
}
xml_parser_free($xml_parser);
echo "";
?>

Gracias.
Los enlaces me han ayudado pero no termino de conseguir hacer funcionar correctamente al parser.

Consigo extraer los datos del archivo XML y mostrarlos aunque no de forma correcta.

Quizas sea porque existen unos parámetros que no entiendo del script:

numberofa ???
maxa ???

Finalmente los datos que recojo los he dejado así:
PRINTED BEFORE

Código:

switch ($name) {
      case "URI":
	     print "<a href='"; 
	     $write = "true"; /* This will print the result */
                     break;
     
      case "URL":
	     print "";
	     $write = "true"; /* This will print the Title */
	     break;	
      case "DESCRIPTION":
	     print "";
	     $write = "true"; /* This will print the Description */
	     break;

PRINTED AFTER

Código:

switch ($name) {
      case "URI":
	    print "'>";
	     $write = "true";
         break;  
      case "URL":
	     print "</a><br>";
	     $write = "true";
	     break;	
      case "DESCRIPTION":
	     print "<br><br>";
	     $write = "true";
	     break;

Pero, se me muestran unos números delante de la URL que no deseo y se muestran tanto la descripción del item anterior como la URL del item siguiente como enlace de texto unido.
¿Porqué?

Ya puestos, me interesaría añadir a las URI las variables:

Código:

ONMOUSEOVER="window.status='http://...';return true" ONFOCUS="window.status='http://...;return true" ONMOUSEOUT="window.status='...'''

y no se como hacerlo.

Una ayudita y no os molesto más. Perdonad mi ignorancia.
