Ciao a tutti, ho il seguente problema, sto eseguendo un progetto in visual c++ 2008 express edition. Ho aggiunto il metodo stampa() in SAXPrintHandler.hpp:
codice:
#include <xercesc/sax/HandlerBase.hpp>
#include <xercesc/framework/XMLFormatter.hpp>
#include <vector>

using namespace std;
XERCES_CPP_NAMESPACE_USE

class SAXPrintHandlers : public HandlerBase, private XMLFormatTarget
{
public:
    // -----------------------------------------------------------------------
    //  Constructors
    // -----------------------------------------------------------------------
    SAXPrintHandlers
    (
        const   char* const                 encodingName
        , const XMLFormatter::UnRepFlags    unRepFlags
    );
    ~SAXPrintHandlers();


    

	//Metodo creato per la stampa dei dati inseriti nel vettore
	
	void stampaStack();

	public : struct PathData {
		wstring element;
		wstring elementText;
			 };
	//}elem;
	vector<PathData> pathdata;

};
L'ho poi implementato in SAXPrintHandler.cpp:
codice:
#include "stdafx.h"
#include <xercesc/util/XMLUniDefs.hpp>
#include <xercesc/sax/AttributeList.hpp>
#include "SAXPrint.hpp"

..........................

void SAXPrintHandlers::startDocument()
{
}
void SAXPrintHandlers::stampaStack()
{
	int len = pathdata.size();
	for (int index = 0; index < len; index++){
		PathData elem = pathdata[index];
		cout<<"Elemento: "<< StrX(elem.element.data())<<"\n";
		cout<<"Elemento Text: "<< StrX(elem.elementText.data())<<"\n";
		cout<<"------------------------------------------------------\n";
	}
	
}

void SAXPrintHandlers::startElement(const   XMLCh* const    name
                                    ,       AttributeList&  attributes)
{
	SAXPrintHandlers::PathData elem;
	elem.element=name;
	pathdata.push_back(elem);
	XERCES_STD_QUALIFIER cout << pathdata.size()<<"\n";
	cout <<StrX(elem.element.data())<< "\n";
    // The name has to be representable without any escapes
    //fFormatter  << XMLFormatter::NoEscapes
           //     << chOpenAngle << name;

    XMLSize_t len = attributes.getLength();
    for (XMLSize_t index = 0; index < len; index++)
    {
		SAXPrintHandlers::PathData p;
		p.element=attributes.getName(index);
		pathdata.push_back(p);
		cout <<"Attributo: "<<StrX(p.element.data())<< "\n";
		cout<<"Valore: "<<StrX(attributes.getValue(index))<< "\n";
        //
        //  Again the name has to be completely representable. But the
        //  attribute can have refs and requires the attribute style
        //  escaping.
        //
      /*  fFormatter  << XMLFormatter::NoEscapes
                    << chSpace << attributes.getName(index)
                    << chEqual << chDoubleQuote
                    << XMLFormatter::AttrEscapes
		            << attributes.getValue(index)
                    << XMLFormatter::NoEscapes
                    << chDoubleQuote;
    }
    fFormatter << chCloseAngle;*/
	}
		
};

Ma se scrivo la seguente linea di codice:
codice:
SAXPrintHandlers::stampaStack();
mi da il seguente errore:

'stampaStack': non è un membro di 'SAXPrintHandlers'

Ho provato a mettere nelle import ma mi solleva troppi errori. Avete un'idea su come risolvere il problema. Per problemi di caratteri a disposizione non ho messo tutto il codice se avete bisogno lo invio in più messaggi. Grazie......
