尝试解析此SOAP响应，但xpath（）正在返回

调试警告：SimpleXMLElement :: xpath（）未定义的名称空间前缀调试警告：SimpleXMLElement :: xpath（）评估失败

 $result = '<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
    <env:Header xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>
    <env:Body xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <v4:TrackReply xmlns:v4="http://fedex.com/ws/track/v4">
            ...
        </v4:TrackReply>
    </env:Body>
</soapenv:Envelope>';


 $xml = simplexml_load_string($result,NULL,NULL,'http://schemas.xmlsoap.org/soap/envelope/');



foreach($xml->xpath('env:Body') as $body){

    //drill down here...
}

Answer 1

尝试将命名空间注册到'env'

$xml->registerXPathNamespace('env', 'http://schemas.xmlsoap.org/soap/envelope/');

修改此代码在body

中设置子元素的名称空间
$bodies = $xml->xpath('env:Body'); foreach($bodies as $body){ $reply = $body->children('v4', TRUE)->TrackReply; var_dump($reply); }

或者，您可以直接使用以下内容获取TrackReply等元素：

$xml->registerXPathNamespace('env', 'http://schemas.xmlsoap.org/soap/envelope/'); $xml->registerXPathNamespace('v4', 'http://fedex.com/ws/track/v4'); var_dump($xml->xpath('env:Body/v4:TrackReply'));

Answer 2

SimpleXML忽略XML结构的env:部分，而是返回如下构造的对象：

SimpleXMLElement Object
(
    [Header] => SimpleXMLElement Object
        (
        )

    [Body] => SimpleXMLElement Object
        (
        )

)

您可以使用以下XPath查询访问正文：$xml->xpath('Body')或只使用以下语法访问该子代：$xml->Body。
