Is er hier een expert in het lezen van xml files.
Heb een probleem
de file ziet er als volgt uit :


<?xml version="1.0" encoding="utf-8"?>
<gpx xmlns:xsd="http://www.w3.org/2001/XMLSchema"

mijn code is :


<?php
$file = "test.gpx" ;

$xml = simplexml_load_file($file);

foreach ($xml->wpt as $wpt) {
   $Breedtegraad= $wpt['lat'] ;
   $Lengtegraad = $wpt['lon'] ;
   $gccode= $wpt->name ;

   $type = explode('|', $wpt->type)[1] ;

   $wpt->registerXPathNamespace('gsak', 'http://www.gsak.net/xmlv1/6');
   $wpt->registerXPathNamespace('groundspeak', 'http://www.groundspeak.com/cache/1/0/1');
   $c = $wpt->children('groundspeak', true);
   $b = $wpt->children('gsak', true);
   $oms= $c->cache->name ;
   $owner = $c->cache->placed_by ;
   $beh= strtoupper($c->cache->container) ;
   $moe= $c->cache->difficulty ;
   $ter= $c->cache->terrain ;
   $land= $c->cache->country ;
   $prov= $c->cache->state ;
   $note= $b->wptExtension->GcNote ;// dit er laatst bijgemaakt
   
}
   
   echo $gccode ;
   echo $note ;
   
   
   ?>

mijn probleem is dat $note leeg blijft terwijl dit in de file niet zo is.
Alle andere van groundspeak worden wel gelezen.
Waar zit mijn fout AUB ?
