Parse XML SOAP response php

Question

我使用以下代码向 SOAP 服务发送请求：

header('Content-type: application/xml');
function doXMLCurl($url,$postXML){
    $CURL = curl_init();
    curl_setopt($CURL, CURLOPT_URL, $url); 
    curl_setopt($CURL, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); 
    curl_setopt($CURL, CURLOPT_POST, 1); 
    curl_setopt($CURL, CURLOPT_POSTFIELDS, $postXML); 
    curl_setopt($CURL, CURLOPT_HEADER, false); 
    curl_setopt($CURL, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($CURL, CURLOPT_HTTPHEADER, array('Accept: text/xml','Content-Type: application/soap+xml'));
    curl_setopt($CURL, CURLOPT_RETURNTRANSFER, true);
    $xmlResponse = curl_exec($CURL); 
    return $xmlResponse;
}
$input_xml = '<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">.....</s:Envelope>';
echo doXMLCurl('webservice_url', $input_xml);

响应也是 XML。

如何解析此数据或转换为数组或对象？我尝试了simplexml_load_string（），但没有成功。

XML 响应：

<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing">
   <s:Header>
      <a:Action s:mustUnderstand="1">...</a:Action>
   </s:Header>
   <s:Body>

                ...
            </b:ListStates>
         </ListStatesResult>
      </ListStatesResponse>
   </s:Body>
</s:Envelope>

Answer 1

假设xml有效，您可以使用 SimpleXMLElement，即：

$xml = new SimpleXMLElement($xmlResponse);
echo $xml->node->otherNode['Id'];

要循环它，请使用：

foreach ($xml->node->otherNode as $el) {
  foreach($el as $key => $val) {
   echo "{$key}: {$val}";
  }
}

Answer 2

我发现最简单的方法是使用 json 函数

$jsonObject = json_decode(json_encode($xmlString));

然后print_r($jsonObject)找到结构。这允许使用$jsonObject->{'@attributes'}->id;访问属性
