将 SOAP XML 响应转换为 PHP 对象或数组 [英] converting SOAP XML response to a PHP object or array
问题描述
我使用 cURL 向 SOAP 服务发送请求，我在 POST Body 中发送包含参数的 XML，作为我收到的响应:
I'm using cURL to send an request to a SOAP service, I send in POST Body the XML containing parameters, in response I receive:

我对 XML 数据的经验不足.我花了几个小时试图将 XML 响应转换为 PHP 对象或数组，但没有成功.
I don't have enough experience with XML data. I spent hours trying to convert the XML response to a PHP object or array, but without any success.
我需要阅读所有的 PropertyResults.
I need to read all PropertyResults.
PHP 代码:
$xml = simplexml_load_string($soap_xml_result);
$xml->registerXPathNamespace('soap', 'http://schemas.xmlsoap.org/soap/envelope/');
$xml->registerXPathNamespace('xsi', 'http://www.w3.org/2001/XMLSchema-instance');
$xml->registerXPathNamespace('xsd', 'http://www.w3.org/2001/XMLSchema');
$test = (string) $xml->Body->SearchResponse->SearchResult->SearchURL;
var_export($test);
推荐答案
bksi 的提示并没有错，但是从技术上讲，因为这是 XML，您只需要正确访问命名空间元素.通过使用 XPath 表达式并将 namspace-uri 注册到您自己的前缀，这会更容易:
The hint of bksi is not that wrong, however technically as this is XML you only need to access the namespaced elements properly. This works more easy by using an XPath expression and registering the namspace-uri to your own prefix:
$soap = simplexml_load_string($soapXMLResult);
$soap->registerXPathNamespace('ns1', 'http://ivectorbookingxml/');
$test = (string) $soap->xpath('//ns1:SearchResponse/ns1:SearchResult/ns1:SearchURL[1]')[0];
var_dump($test);
输出:
string(100) "http://www.lowcostholidays.fr/dl.aspx?p=0,8,5,0&date=10/05/2013&duration=15&room1=2,1,0_5®ionid=9"
如果不想使用XPath，则需要在遍历时指定命名空间，如果元素本身没有前缀，则只有元素本身的命名空间中的子元素直接可用.由于根元素是前缀，您首先需要遍历响应:
If you don't want to use XPath, you need to specify the namespace while you traverse, only the children in the namespace of the element itself are available directly if the element itself is not prefixed. As the root element is prefixed you first need to traverse up to the response:
$soap = simplexml_load_string($soapXMLResult);
$response = $soap->children('http://schemas.xmlsoap.org/soap/envelope/')
->Body->children()
->SearchResponse
;
然后你可以使用你所知道的 $response 变量:
Then you can make use of the $response variable as you know it:
$test = (string) $response->SearchResult->SearchURL;
因为该元素没有前缀.当返回更复杂的结果时，这可能是最好的，因为您可以轻松访问所有响应值.
because that element is not prefixed. As a more complex result is returned this is probably the best because you can easily access all the response values.
