et je construis le message s suivi:

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; 

... 

la question est: Lorsqu'un xsd contient un xs: choix, gsoap générer une union à utiliser par tableau dynamique, le problème est que chaque _union_Body gsoap il rend avec l'élément parent inclus

<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> 

Comment puis-je éviter cela?

merci d'avance !!

Je trouve la solution:. de GENIVIA Doc " Un membre devient un élément XML caché, c.-à-pas visiblement rendu en XML, lorsque son nom commence par un double underscore Cela permet de séquencer une collecte de données membres, essentiellement en formant une séquence d'éléments qui peuvent être facultatifs ou répétés ensemble.

avis que j'ai renommé _unionody_BODY de classe à ___ unión_BODY et _BODY de nom variable ___BODY

merci beaucoup.
