How to parse SOAP XML?
提问by Anton
SOAP XML:
SOAP XML：
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<PaymentNotification xmlns="http://apilistener.envoyservices.com">
<payment>
<uniqueReference>ESDEUR11039872</uniqueReference>
<epacsReference>74348dc0-cbf0-df11-b725-001ec9e61285</epacsReference>

<bankCurrency>EUR</bankCurrency>
<bankAmount>1.00</bankAmount>
<appliedCurrency>EUR</appliedCurrency>
<appliedAmount>1.00</appliedAmount>
<countryCode>ES</countryCode>

How to get 'payment' element?
如何获得“付款”元素？
I try to parse (PHP)
我尝试解析（PHP）
$xml = simplexml_load_string($soap_response);
$xml->registerXPathNamespace('soap', 'http://schemas.xmlsoap.org/soap/envelope/');
foreach ($xml->xpath('//payment') as $item)
{
print_r($item);
}
Result is empty :( Any ideas how to parse it correct?
结果为空 :( 任何想法如何正确解析它？

One of the simplest ways to handle namespace prefixes is simply to strip them from the XML response before passing it through to simplexml such as below:
处理命名空间前缀的最简单方法之一就是在将它们传递给 simplexml 之前将它们从 XML 响应中剥离，如下所示：
$your_xml_response = '<Your XML here>';
$clean_xml = str_ireplace(['SOAP-ENV:', 'SOAP:'], '', $your_xml_response);
$xml = simplexml_load_string($clean_xml);
This would return the following:
这将返回以下内容：
SimpleXMLElement Object
(
[Body] => SimpleXMLElement Object
(
[PaymentNotification] => SimpleXMLElement Object
(
[payment] => SimpleXMLElement Object
(
[uniqueReference] => ESDEUR11039872
[epacsReference] => 74348dc0-cbf0-df11-b725-001ec9e61285
[postingDate] => 2010-11-15T15:19:45
[bankCurrency] => EUR
[bankAmount] => 1.00
[appliedCurrency] => EUR
[appliedAmount] => 1.00
[countryCode] => ES
[bankInformation] => Sean Wood
[merchantReference] => ESDEUR11039872
)
)

PHP version > 5.0 has a nice SoapClient integrated. Which doesn't require to parse response xml. Here's a quick example
PHP 版本 > 5.0 集成了一个很好的 SoapClient。不需要解析响应xml。这是一个快速示例
$client = new SoapClient("http://path.to/wsdl?WSDL");
$res = $client->SoapFunction(array('param1'=>'value','param2'=>'value'));
echo $res->PaymentNotification->payment;

In your code you are querying for the paymentelement in default namespace, but in the XML response it is declared as in http://apilistener.envoyservices.comnamespace.
在您的代码中，您正在查询payment默认命名空间中的元素，但在 XML 响应中，它被声明为在http://apilistener.envoyservices.com命名空间中。
So, you are missing a namespace declaration:
因此，您缺少命名空间声明：
$xml->registerXPathNamespace('envoy', 'http://apilistener.envoyservices.com');
Now you can use the envoynamespace prefix in your xpath query:
现在您可以envoy在 xpath 查询中使用命名空间前缀：
xpath('//envoy:payment')
The full code would be:
完整的代码是：
$xml = simplexml_load_string($soap_response);
$xml->registerXPathNamespace('envoy', 'http://apilistener.envoyservices.com');
foreach ($xml->xpath('//envoy:payment') as $item)
{
print_r($item);
}
Note: I removed the soapnamespace declaration as you do not seem to be using it (it is only useful if you would use the namespace prefix in you xpath queries).
注意：我删除了soap命名空间声明，因为您似乎没有使用它（只有在 xpath 查询中使用命名空间前缀时才有用）。

First, we need to filter the XML so as to parse that into an object
首先，我们需要过滤 XML 以便将其解析为一个对象
$response = strtr($xml_string, ['</soap:' => '</', '<soap:' => '<']);
$output = json_decode(json_encode(simplexml_load_string($response)));
var_dump($output->Body->PaymentNotification->payment);

First, we need to filter the XML so as to parse that change objects become array
首先，我们需要过滤 XML 以便解析更改对象成为数组
//catch xml
$xmlElement = file_get_contents ('php://input');
//change become array
$Data = (array)simplexml_load_string($xmlElement);
//and see
print_r($Data);
回答by omarjebari
This is also quite nice if you subsequently need to resolve any objects into arrays: $array = json_decode(json_encode($responseXmlObject), true);
如果您随后需要将任何对象解析为数组，这也非常好： $array = json_decode(json_encode($responseXmlObject), true);

why don't u try using an absolute xPath
为什么不尝试使用绝对 xPath
//soap:Envelope[1]/soap:Body[1]/PaymentNotification[1]/payment
or since u know that it is a payment and payment doesn't have any attributes just select directly from payment
或者因为你知道它是一种付款并且付款没有任何属性，所以直接从付款中选择
//soap:Envelope[1]/soap:Body[1]/PaymentNotification[1]/payment/*
