Question

我正在使用simplexml来解析curl响应。我正确地得到了回复，但无法从响应中获取某些属性......

//Sending my data to web service
$curl = curl_init();
curl_setopt_array($curl, Array(
    CURLOPT_URL            => 'https://webservice.tld',
    CURLOPT_POST           => count($xml->asXML()),
    CURLOPT_POSTFIELDS     => $xml->asXML(),
    CURLOPT_TIMEOUT        => 120,
    CURLOPT_CONNECTTIMEOUT => 30,
    CURLOPT_RETURNTRANSFER => TRUE,
    CURLOPT_ENCODING       => 'UTF-8'
));

//Get the response
$reply = curl_exec($curl);

$responseData = simplexml_load_string($reply);

//Print the response
print_r($responseData);

然后将xml响应正确显示为：

<?xml version="1.0" encoding="utf-16"?>
<cXML payloadID="test" xml:lang="en" timestamp="2017-09-13T09:49:58.1219095+01:00">
  <Response>
    <Status code="500" text="Price does not match current pricelist" />
  </Response>
</cXML>

但是，我正试图从状态中获取代码和文本属性，但它没有输出任何内容;

echo $responseData->Response->Status['code'] .' - '. $responseData->Response->Status['text'];

我也试过了;

echo $responseData->cXML->Response->Status['code'] .' - '. $responseData->cXML->Response->Status['text'];

想知道是否有人可以提供帮助？

感谢。

Answer 1

你可以这样做。

foreach($responseData->Response->Status->attributes() as $key => $val){
 echo $key .'='. $val;
}

这就是你可以阅读它的php文档here

Answer 2

你得到的问题（这就是为调试设置错误消息的原因）是......

<?php
error_reporting ( E_ALL );
ini_set ( 'display_errors', 1 );

$reply = <<< XML
<?xml version="1.0" encoding="utf-16"?>
<cXML payloadID="test" xml:lang="en" timestamp="2017-09-13T09:49:58.1219095+01:00">
  <Response>
    <Status code="500" text="Price does not match current pricelist" />
  </Response>
</cXML>
XML;
$responseData = simplexml_load_string($reply);

...给出

Warning: simplexml_load_string(): Entity: line 1: parser error : Document labelled UTF-16 but has UTF-8 content in /home/nigel/workspace/PHPTest/TestSource/t1.php on line 15

如果您将utf-16更改为utf-8，那么这将解析确定，您的原始代码应该可以正常工作。

<?php
error_reporting ( E_ALL );
ini_set ( 'display_errors', 1 );

$reply = <<< XML
<?xml version="1.0" encoding="utf-16"?>
<cXML payloadID="test" xml:lang="en" timestamp="2017-09-13T09:49:58.1219095+01:00">
  <Response>
    <Status code="500" text="Price does not match current pricelist" />
  </Response>
</cXML>
XML;
$reply = preg_replace('/(<\?xml[^?]+?)utf-16/i', '$1utf-8', $reply);
$responseData = simplexml_load_string($reply);

//Print the response
echo $responseData->Response->Status['code'];

如果生成XML的人修复了这个问题，那将是理想的，但是现在这将有助于解决问题。
