在PHP中使用SOAP Web服务

Question

我正在尝试建立一个使用Web服务的客户端，并且遇到了一些奇怪的问题。 这是我的代码：

$securityCode = "A7D5B7D8-73E2-44D2-A6F8-4ACFB91843BF"; // The security code has been changed to an invalid code to prevent unwanted "visitors".
$ProphecyConnect = new SoapClient("http://test.prophecyhealth.com/ProphecyConnect/ProphecyConnectXML.cfc?wsdl");
try
{
    $params = array(SecurityCode => $securityCode, AssessmentID => -1, AssessmentType => "Test");
    $assessmentList = $ProphecyConnect->__soapCall("GetAssessments", array($params));
}
catch(Exception $exception)
{
    var_dump($exception);
}
$xml = new DOMDocument();
$xml->loadXML( $assessmentList );
try
{
    foreach($xml->getElementsByTagName("assessment") as $assessment)
    {
        foreach($assessment->childNodes as $node)
        {
            printf(
            "Name: %s - Type: %s - Value: %s\n",
            $node->nodeName,
            $node->nodeType,
            urlencode($node->nodeValue)     
            );
        }
    }
}
catch(Exception $ex)
{
    echo "Something happened.";
    var_dump($ex);
}

我的问题是getElementByTagName找不到任何东西。 这是从Web服务返回的XML：

<object>
    <success>true</success>
    <count>3</count>
    <assessments>
        <assessment>
            <assessmentid><![CDATA[123]]></assessmentid>
            <assessmentname><![CDATA[Cardiac Cath Lab V1]]></assessmentname>
            <assessmenttype><![CDATA[Test]]></assessmenttype>
            <costpoints><![CDATA[1]]></costpoints>
            <numberofquestions><![CDATA[23]]></numberofquestions>
            <timelimit><![CDATA[1380]]></timelimit>
        </assessment>
        <assessment>
            <assessmentid><![CDATA[456]]></assessmentid>
            <assessmentname><![CDATA[Cardiac Progressive Care Exam A V1]]></assessmentname>
            <assessmenttype><![CDATA[Test]]></assessmenttype>
            <costpoints><![CDATA[1]]></costpoints>
            <numberofquestions><![CDATA[75]]></numberofquestions>
            <timelimit><![CDATA[4500]]></timelimit>
        </assessment>
        <assessment>
            <assessmentid><![CDATA[789]]></assessmentid>
            <assessmentname><![CDATA[Cardiac Progressive Care Exam B V1]]></assessmentname>
            <assessmenttype><![CDATA[Test]]></assessmenttype>
            <costpoints><![CDATA[1]]></costpoints>
            <numberofquestions><![CDATA[75]]></numberofquestions>
            <timelimit><![CDATA[4500]]></timelimit>
        </assessment>
    </assessments>
</object>

就PHP而言，我相当n00b，但据我所知，这看起来很正确（至少很接近）。 我敢肯定，虽然我遗失了一些明显的东西。

谢谢

事实证明，SOAP调用返回一个对象，而不是字符串。 因此，当我将$ assessmentList变量传递给$ xml.loadXML（）函数时，我实际上需要传递包含xml的属性。 像这样：

$xml->loadXML($assessmentList->GetAssessmentsReturn);

这工作得很好。
