      </v10:RateReplyDetails>
    </v10:RateReply>
  </soapenv:Body>
</soapenv:Envelope>

Code:

$fedex_xml = simplexml_load_string($fedex_response); 
$RateReplyDetails = $fedex_xml->children("soapenv", true)->Body->children("v10", true)->RateReply->children()->RateReplyDetails;
var_dump($RateReplyDetails);        

foreach ($RateReplyDetails as $details) {
     print_r($details);
}

I am trying loop through the <v10:RateReplyDetails> nodes.

Answer 1

I was on the right lines, answer below:

$fedex_xml = simplexml_load_string($fedex_response);

$RateReply = $fedex_xml->children("env", true)->Body->children("v13", true)->RateReply;
foreach($RateReply->RateReplyDetails as $details){

}
