如何从soap:header中获取SessionID？

Question

我得到了soap响应，我需要SessionID。我试图使用SimpleXml_load_string，但得到了一个空对象。有谁知道如何获得SessionID吗？

这是xml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">
<soap:Header>
    <Header xmlns="http://www.twinfield.com/">
        <SessionID>ca363c52-c12f-4988-b06a-e0c41788e254</SessionID>
    </Header>
</soap:Header>
<soap:Body>
    <LogonResponse xmlns="http://www.twinfield.com/">
        <LogonResult>Ok</LogonResult>
        <nextAction>None</nextAction>
        <cluster>https://c3.twinfield.com</cluster>
    </LogonResponse>
</soap:Body>
</soap:Envelope>

尝试使用DOM。这是一种方法：

$s = '<?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">
<soap:Header>
    <Header xmlns="http://www.twinfield.com/">
        <SessionID>ca363c52-c12f-4988-b06a-e0c41788e254</SessionID>
    </Header>
</soap:Header>
<soap:Body>
    <LogonResponse xmlns="http://www.twinfield.com/">
        <LogonResult>Ok</LogonResult>
        <nextAction>None</nextAction>
        <cluster>https://c3.twinfield.com</cluster>
    </LogonResponse>
</soap:Body>
</soap:Envelope>';

$doc   = new DOMDocument();
$doc->loadXML( $s );
echo $doc->getElementsByTagName('SessionID')->item(0)->nodeValue;
