php – 无法使用SimpleXML解析Soap响应

Warning: simplexml_load_string() [function.simplexml-load-string]: 
Entity: line 1: parser error : Extra content at the end of the document

这看起来不像命名空间问题,我已经尝试过网站上其他地方提到的补丁来从输入字符串中删除冒号.

谢谢,戈登

你是对的.该服务器是使用数据集的Microsoft站点.

如果我将soap客户端声明为trace设置为true：

$soapClient = new soapclient($this->wsdlUrl,array('trace'=>true));

然后从响应中检索原始XML：

$soapResult = $soapClient->GetScheduledSectors();
$responseXml = $soapClient->__getLastResponse();
$xml = simplexml_load_string($responseXml,NULL,"http://schemas.xmlsoap.org/soap/envelope/");

然后我得到：

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

响应XML标头和第一个标签如下所示：

<?xml version='1.0'?> 
<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:Body>

  <GetScheduledSectorsResponse xmlns="https://www.kulula.com/k3api/">

     <GetScheduledSectorsResult msdata:SchemaSerializationMode="ExcludeSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">

        <xs:schema id="dsFlight" targetNamespace="http://tempuri.org/dsFlight.xsd" attributeFormDefault="qualified" elementFormDefault="qualified" xmlns:mstns="http://tempuri.org/dsFlight.xsd" xmlns="http://tempuri.org/dsFlight.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msprop="urn:schemas-microsoft-com:xml-msprop">

           <xs:element name="dsFlight" msdata:IsDataSet="true" msdata:UseCurrentLocale="true" msprop:ExecutionTime="1140">

              <xs:complexType>

                 <xs:choice minOccurs="0" maxOccurs="unbounded"/>

              </xs:complexType>

           </xs:element>

        </xs:schema>

        <diffgr:diffgram xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1">

           <dsFlight xmlns="http://tempuri.org/dsFlight.xsd">

              <FlightSector diffgr:id="FlightSector1" msdata:rowOrder="0">

                 <FlightSectorId>1</FlightSectorId>

                 <FlightSectorName>JNBCPT</FlightSectorName>

                 <FromAirport>O.R. Tambo (Jo'burg)</FromAirport>

                 <ToAirport>Cape Town</ToAirport>

                 <DepartureAirportId>1</DepartureAirportId>

                 <ArrivalAirportId>2</ArrivalAirportId>

                 <AirlineCode>BA</AirlineCode>

                 <Ordernumber>100</Ordernumber>

                 <FlightZoneId>1</FlightZoneId>

                 <DepartureCountryCode>ZA</DepartureCountryCode>

                 <DepartureContinentCode>AF</DepartureContinentCode>

              </FlightSector>

我还尝试注册以下命名空间：

$xml = simplexml_load_string($this->responseXml,"http://schemas.xmlsoap.org/soap/envelope/");
    $xml->registerXPathNamespace('soap','http://schemas.xmlsoap.org/soap/envelope/');
    $xml->registerXPathNamespace('xsi','http://www.w3.org/2001/XMLSchema-instance');
    $xml->registerXPathNamespace('xsd','http://www.w3.org/2001/XMLSchema');
    $xml->registerXPathNamespace('diffgr','urn:schemas-microsoft-com:xml-diffgram-v1');
    $xml->registerXPathNamespace('mstns','http://tempuri.org/dsFlight.xsd');
    $xml->registerXPathNamespace('msprop','urn:schemas-microsoft-com:xml-msprop');

但仍然在$xml中获得一个空对象
