I am using PHP curl to get data from remote with
this PHP code :
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'http://hostanme.tld/ERP_PAY_XML.xml');
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
//echo $result;
curl_close($ch);
$xml = simplexml_load_string($result);
$ns = $xml->getNamespaces(true);
$soap = $xml->children($ns['env']);
echo "<br> len-soap : " . $soap;
$getaddressresponse = $soap->Body->children($ns['n0']);
foreach ($getaddressresponse->getLocationForGroupResponse->children($ns['n0']) as $item)
{
$item = $item->children();
echo $item->address . '<br />';
}
?>
but still I am not getting any result. Anybody please help..
Is there any other way to parse XML to an object..
