I am trying to parse the namespace Rate under the QuoteDetail section. Here is my response from the web service. Any help on getting that Rate node extracted would be awesome.

This is the code I am using to try and parse but getting error: Call to a member function children() on string

$xml = $curl->response;
$rate = (string)$xml->children('soap', true)->Body->RateQuoteByAccountResponse->RateQuoteByAccountResult->RateDetails->QuoteDetail->Rate;

Try wrapping xml string around as follow:

<?php
$string = '<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

</RateQuoteByAccountResult>
</RateQuoteByAccountResponse>
</soap:Body>
</soap:Envelope>';

$string = <<<XML
$string
XML;

$XmlArray = new SimpleXMLElement($string);
echo $ErrorCode = $XmlArray->children("soap", true)->Body->
                    children()->RateQuoteByAccountResponse->
                    children()->RateQuoteByAccountResult->children()->RateDetails->children()->QuoteDetail->children()->Rate;
?>

You'll get first Rate - 106.69 from the list.
