Ok, ive found it in my library.
Could you please do me a massive favour & show a step by step of your
process. To be honest im not totally understanding your logic to achieve my
goal. Also because its not documented its harder to impliment.
Disclaimer: it's a totally untested code...
#include <xercesc/util/StringPool.hpp>
class myHandler : public DocumentHandler
{
[...]
virtual void startDocument();
virtual void startElement
(
const XMLCh* const name
, AttributeList& attrs
);
protected:
XMLStringPool _map;
};
void myHandler::startDocument()
{
_map.flushAll();
_map.addOrFind(L"loopcardprj"); // id = 1
_map.addOrFind(L"_prjsetup"); // id = 2
_map.addOrFind(L"title"); // id = 3
_map.addOrFind(L"author"); // id = 4
_map.addOrFind(L"subject"); // id = 5
_map.addOrFind(L"card"); // id = 6
_map.addOrFind(L"_questions"); // id = 7
_map.addOrFind(L"question"); // id = 8
_map.addOrFind(L"q"); // id = 9
_map.addOrFind(L"a"); // id = 10
_map.addOrFind(L"comment"); // id = 11
}
void myHandler::startElement(const XMLCh* const name, AttributeList& attrs)
{
switch(_map.getId(name))
{
// place the code in the corresponding 'case' branch...
case 1:
case 2:
case 3:
case 4:
case 5:
case 6:
case 7:
case 8:
case 9:
case 10:
case 11:
}
}
