如何从SOAP回复信封中读取error_code？我的
PHP版本是：5.2.0.
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
<soap:Body>
<Response xmlns="http://xxx.gateway.xxx.abcd.com">
<return>
<transaction_id>1234567</transaction_id>
<error_code>109</error_code>
</return>
</Response>
</soap:Body>
</soap:Envelope>
我只需要读取error_code tag的值.其值为：109
我正在使用nusoap.我使用下面的代码但没有正常工作：
$response=htmlspecialchars($client->response,ENT_QUOTES); $xml = simplexml_load_string($response); $ns = $xml->getNamespaces(true); $soap = $xml->children($ns['soap']); $error_code = $soap->body->children($ns['error_code']);
<?PHP $string = <<<XML <soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope"> <soap:Body> <Response xmlns="http://xxx.gateway.xxx.abcd.com"> <return> <transaction_id>1234567</transaction_id> <error_code>109</error_code> </return> </Response> </soap:Body> </soap:Envelope> XML; $xml = new SimpleXMLElement($string); $xml->registerXPathNamespace("soap","http://www.w3.org/2003/05/soap-envelope"); $body = $xml->xpath("//soap:Body"); $error_code = (string)$body[0]->Response->return->error_code; print_r($error_code); ?>
要么
$xml = simplexml_load_string($string);
$error_code = (string)$xml->children('soap',true)
->Body
->children()
->Response
->return
->error_code;
