Hi,

I perform a simple test with a simple XML file :
the code :
-------------

//Initialization ConfigurationServer & Loader
FileConfigLoader fileConfigLoader;
ConfigurationServer<> configurationServer ;
                        
std::wstring file3;
file3.append(L"PhysicalEnt.xml");
fileConfigLoader.addRepository(L"/Root/entities.*",file3); 
configurationServer.setLoader(&fileConfigLoader);
                
/* Test 1: ConfigDOMNodeListPtr entitieslist3 = 
configurationServer.selectNodes(L"/Root/entities/*"); */
ConfigDOMNodePtr entNode = configurationServer.selectSingleNode 
(L"/Root/entities");
ConfigDOMNodeListPtr entitieslist = entNode->selectNodes(L"entity");
/* Test 2 :ConfigDOMNodeListPtr entitieslist = entNode->selectNodes(L"*"); */
                                                
//fill the map                                  
for (int i=0; i< entitieslist->get_length() ; i++) 
{
std::cout <<  " Iteraction : " << i << std::endl;

        //gathering data for the map key                                
        ConfigDOMNodePtr structElem  = entitieslist->nextNode();
        ConfigDOMNodeListPtr structParamsNodes = 
structElem->selectNodes(L"physicalEntity/entityType/*");

        unsigned int entityKind         = 
(ConfigurationServer<>::NodeConverter) structParamsNodes->nextNode();
        unsigned int domain     = (ConfigurationServer<>::NodeConverter) 
structParamsNodes->nextNode();

std::cout <<  " EntityKind : " << entityKind << std::endl;
}


The XML file : 
-------------------
Fichier 'PhysicalEnt.xml':
<entities>
    <entity>
        <physicalEntity>
            <entityType>
                <entityKind>1</entityKind>
                <domain>1</domain>
                <countryCode>1</countryCode>
                <category>1</category>
                <subcategory>1</subcategory>
                <specific>1</specific>
                <extra>1</extra>
            </entityType>
        </physicalEntity>
    </entity>
    <entity>
        <physicalEntity>
            <entityType>
                <entityKind>2</entityKind>
                <domain>2</domain>
                <countryCode>2</countryCode>
                <category>2</category>
                <subcategory>2</subcategory>
                <specific>2</specific>
                <extra>2</extra>
            </entityType>
        </physicalEntity>
    </entity>
</entities>

I can't fix the problem.
I rebuild Xalan, but the same.

Thanks;
Fred.
