[xsd-users] retrieving data from gml:featureMember

[Jan Pauwels]

Hello,
 
I am not so familiar with C++.
I want to retreive data from hello9.xml. (Extract from file follows)
 
  <gml:featureMember>
    <BP_Plan gml:id="obj_0">
   </BP_Plan>
 </gml:featureMember>
 
 
I use the following code : (copied from example polymorphism)
 
    auto_ptr<xplangml::XPlanAuszugType> Auszug (xplangml::XPlanAuszug
(argv[1]));
 
    xplangml::XPlanAuszugType copy (*Auszug); // Dynamic types are
preserved in copies.
 
    // Print what we've got.
    //
    for
(gml::AbstractFeatureCollectionType::featureMember_const_iterator i
(copy.featureMember().begin());
         i != copy.featureMember ().end ();
         ++i)
    {
      if (const xplangml::BP_PlanType* s = dynamic_cast<const
xplangml::BP_PlanType*> (&*i))
        cout << "BP_Plan" << endl;
      else
        cout << "no BP_Plan" << endl;
    }
 
The output is always "no BP_Plan".
featureMember can be BP_Plan, BP_... (lots of possible elements).
How can I retrieve data for element BP_Plan ?
Do I have to use an if-statement for each BP_ element that I want to
retrieve ?
   example :
         if (const xplangml::BP_PlanType* s = dynamic_cast<const
xplangml::BP_PlanType*> (&*i))
         else if (const xplangml::BP_BereichType* s = dynamic_cast<const
xplangml::BP_BereichType*> (&*i))

 
I attached the XML-files + schemas.
 
 
 
Thank you in advance.
 
Greetings.
