介绍
不确定您从哪里获得$xpath->registerNamespace('api', 'http://127.0.0.1/Integrics/Enswitch/API');
但不是有效的namespace
去获取您可以使用的所有有效名称空间
$sxe = new SimpleXMLElement($xml);
print_r($sxe->getDocNamespaces(true));
输出
Array
(
[xsi] => http://www.w3.org/2001/XMLSchema-instance
[soapenc] => http://schemas.xmlsoap.org/soap/encoding/
[xsd] => http://www.w3.org/2001/XMLSchema
[soap] => http://schemas.xmlsoap.org/soap/envelope/
[] => http://www.flatplanetphone.net/Integrics/Enswitch/API
)
你来自Pastbin的 XML
$xml = '<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><get_cdrsResponse
xmlns="http://www.flatplanetphone.net/Integrics/Enswitch/API">
<s-gensym3>
<scustomer xsi:type="xsd:string">4458</scustomer>
<recording xsi:type="xsd:string" />
<outgroup_name xsi:type="xsd:string">abc</outgroup_name>
<bill_type xsi:type="xsd:string">prepaid</bill_type>
</s-gensym3>
</get_cdrsResponse>
</soap:Body>
</soap:Envelope>';
解决方案
$sxe = new SimpleXMLElement($xml);
$sxe->registerXPathNamespace("api", "http://www.flatplanetphone.net/Integrics/Enswitch/API");
$path = $sxe->xpath("//api:s-gensym3");
$info = array_shift($path);
if (!$info)
throw new Exception("Invalid Response");
echo $info->scustomer, PHP_EOL;
echo $info->recording, PHP_EOL;
echo $info->outgroup_name, PHP_EOL;
echo $info->bill_type, PHP_EOL;
输出
4458
abc
prepaid

在处理多个孩子时,您可以忽略命名空间并使用SimpleXMLElement::children
