PHP and Simplecml_load_string and Xpath to echo specific Value

Question

我有以下 SOAP 响应：

<?xml version="1.0" encoding="utf-8"?>

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">

</soap:Header>

<soap:Body>
<RetrieveResponseMsg xmlns="http://exacttarget.com/wsdl/partnerAPI">
    <OverallStatus>OK</OverallStatus>
    <RequestID>12af20a5-b76e-4043-ae76-XXXXXXXX</RequestID>
    <Results xsi:type="Subscriber">
        <PartnerKey xsi:nil="true" />
        <ObjectID xsi:nil="true" />
        <EmailAddress>hrajput@testing.com</EmailAddress>
        <Status>Active</Status></Results>
    <Results xsi:type="Subscriber">
        <PartnerKey xsi:nil="true" />
        <ObjectID xsi:nil="true" />
<EmailAddress>hrajput@testing.com</EmailAddress>
<Status>Active</Status></Results>
</RetrieveResponseMsg>
</soap:Body></soap:Envelope>

我正在尝试回显/存储上述响应中的 EmailAddress，以便稍后在脚本中使用它。

我做的是这样的：

$xmlstring = $client->__getLastResponse();

// Loads the XML
$xml = simplexml_load_string($xmlstring);

//print $xml->asXML();

echo "Result:".$xml->children('http://schemas.xmlsoap.org/soap/envelope/')->Body->children('http://exacttarget.com/wsdl/partnerAPI')->Results[0]->EmailAddress;

但是我一直收到这个错误：

Fatal error: Call to a member function children() on a non-object in

我真的很想抓住 EmailAddress。我该怎么做？

Answer 1

尝试找出是否正在创建对象

// Loads the XML
$xml = simplexml_load_string($xmlstring);
if (false === $xml) {
    throw new RuntimeException("Error: Cannot create object");
}

如果没有创建对象。然后你可能需要检查你得到的XML。

Answer 2

xml路径错误，忘记了RetrieceResponseMsg。

正确的路径是：

$xml->children("http://schemas.xmlsoap.org/soap/envelope/")->Body->children("http://exacttarget.com/wsdl/partnerAPI")->RetrieveResponseMsg->Results->EmailAddress
