gSOAP的XS：選擇渲染重複父元素

Question

我有以下XSD片：

<xs:element name="MESSAGE"> 
    <xs:complexType> 
     <xs:sequence> 
     <xs:element ref="HEADER"/> 
     <xs:element ref="BODY" minOccurs="1" maxOccurs="1"/> 
     </xs:sequence> 
     <xs:attribute name="VERSION" type="xs:unsignedInt" use="required"/> 
    </xs:complexType> 
    </xs:element> 

...

<xs:element name="BODY"> 
    <xs:complexType> 
     <xs:choice maxOccurs="2"> 
     <xs:element ref="LANE" minOccurs="0" maxOccurs="1"/> 
     <xs:element ref="DEVICE" minOccurs="0" maxOccurs="unbounded"/> 
     <xs:element ref="TRIP" minOccurs="0" maxOccurs="1"/> 
     <xs:element ref="CASH_DISPOSAL" minOccurs="0" maxOccurs="1"/> 
     <xs:element ref="ISSUE" minOccurs="0" maxOccurs="1"/> 
     <xs:element ref="SHIFT" minOccurs="0" maxOccurs="1"/> 
     <xs:element ref="SALE_RECHARGE" minOccurs="0" maxOccurs="1"/> 
     <xs:element ref="LIFE" minOccurs="0" maxOc`enter code here`curs="1"/> 
     <xs:element ref="OBSERVATION" minOccurs="0" maxOccurs="1"/> 
     <xs:element ref="SURVEY_RESPONSE" minOccurs="0" maxOccurs="1"/>

     <xs:element ref="DEBT_CANCELLATION" minOccurs="0"/> 
     </xs:choice> 
    </xs:complexType> 
    </xs:element>

這是由gSOAP的產生soapStub：

我建立的消息a S請按照：

MESSAGE soapMSG; 
    HEADER soapHeader; 
    BODY soapBody; 
    LANE soapLane; 

    ... 

soapMSG.BODY_ = std::make_shared<BODY>(); // here i use a maping pointer to sharedptr 

     soapMSG.BODY_->_BODY = new ((_union_BODY *)soap_malloc(ctx, 2 * sizeof(_unionBody))) _union_BODY[2]; 

     soapMSG.BODY_->__size_BODY = 2; 

     soapMSG.BODY_->_BODY[0].__union_BODY = SOAP_UNION_union_BODY_LANE_; 

     soapMSG.BODY_->_BODY[0]._BODY.LANE_ = &soapLane; 

... 

的問題是： 當XSD包含的xs：選擇，gSOAP的產生並集以通過動態陣列一起使用，問題是，每_union_Body gSOAP的與父元件包括

使其

<MESSAGE xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" VERSION="0">

      </BODY> 
... 
     </BODY> 
    </MESSAGE> 

我該如何避免這種情況？

預先感謝您！

我找到了解決辦法： 從GENIVIA文件 「 成員成爲一個隱藏的XML元素，即不是XML明顯呈現，當它的名字以雙下劃線開始這使得測序數據的集合成員，基本上是通過形成一系列可以選擇或重複的元素。「 然後我修改由gSOAP的產生.H：

// END OF CHOICE

    struct soap       *soap       ;

到：我已重命名類_unionody_BODY將___unión_BODY和德變量名_BODY到___BODY

謝謝
