FUNCION XML2Array

[nomakon]

Buenas, tengo el siguiente problema

Utilizo la funcion creada x:

/**
* xml2array() will convert the given XML text to an array in the XML structure.
* Link: http://www.bin-co.com/php/scripts/xml2array/
*/


Al obtener el XML

Código:

<xml_api_reply version="1">
<weather module_id="0" tab_id="0" mobile_row="0" mobile_zipped="1" row="0" section="0">

Observamos que hay tildes, o ñ. Como hago para que cuando llame mediante file get contents al fichero XML

Código PHP:

  $contents = file_get_contents($url);  
   

Este me lo devuelva sin tildes o ñ?

Ya he probado con esto:

Código PHP:

  function QuitarTildes($cadena) { 
     
$no_permitidas= array ("á","é","í","ó","ú","Á","É","Í","Ó","Ú","ñ","À","Ã","Ì","Ò","Ù","Ù","à","è","ì","ò","ù","ç","Ç","â","ê","î","ô","û","Â","Ê","ÃŽ","Ô","Û","ü","ö","Ö","ï","ä","«","Ò","Ã�","Ä","Ë"," "); 
 
$permitidas= array ("a","e","i","o","u","A","E","I","O","U","n","N","A","E","I","O","U","a","e","i","o","u","c","C","a","e","i","o","u","A","E","I","O","U","u","o","O","i","a","e","U","I","A","E","%2C"); 
 
$texto = str_replace($no_permitidas, $permitidas ,$cadena); 
 
return $texto; 
}  
   

sobre la variable $contents pero nada...

Alguien me enseña el camino ? =)
