Hello Alberto,
the XMLPlatformUtils::Initialize() function leads to a crash in Xerces
2.8
The code is like:
try
{
XERCES_CPP_NAMESPACE::XMLPlatformUtils::Initialize();
}
catch (XERCES_CPP_NAMESPACE::XMLException& e)
{
CString cstrTraceMsg;
cstrTraceMsg.Format(_T("ERROR: Internal DOM Error - An error
occurred during creation of output transcoder. Exception code: %d Msg is :
%s"), e.getCode(),e.getMessage());
TRACE_ERROR(CLString(cstrTraceMsg),ERR_DOM_OPERATION_FAILED);
}
catch(...)
{
TRACE_INFO("CSPVXMLParserWrapper::CreateDOMTree()
XMLPlatformUtils::Initialize - threw an exception");
}
I always get the control into the generic catch block than the XMLException
catch
when could this happen? any idea?
regards,
Pranav
