Hi,
I am starting to play with with C++ and I have some questions.
I need to parse a XML file that describes a smart card file structure
and to initialize my data structure.
First I chose this structure :
A CCardObject has files (index by SFID) and each file has
records(indexed by RecNo) and each record can be splitted into
data(index by string).
class CDataIndex
{
public :
int m_nSFID; // FileID
int m_nRecNo; // RecNo
int m_nOffset; // Offset
int m_nSize; // DataLen
CDataIndex() { }
CDataIndex(int nSFID, int nRecNo, int nOffset, int size) {
m_nSFID = nSFID;
m_nRecNo = nRecNo;
m_nOffset = nOffset;
m_nSize = size;
}
CDataIndex(const CDataIndex& ob)
{
m_nSFID = ob.m_nSFID;
m_nRecNo = ob.m_nRecNo;
m_nOffset = ob.m_nOffset;
m_nSize = ob.m_nSize;
}
void operator = (const CDataIndex& ob)
{
m_nSFID = ob.m_nSFID;
m_nRecNo = ob.m_nRecNo;
m_nOffset = ob.m_nOffset;
m_nSize = ob.m_nSize;
}
};
class CCardRecord
{
public :
int m_nRecNo;
int m_nRecSize;
map<int, BYTE[29]> m_RecData;
CCardRecord() {}
CCardRecord( int nRecNo ) { m_nRecNo = nRecNo;}
int GetRecNo() { return m_nRecNo; }
int GetRecSize() { return m_nRecSize; }
int GetData(int nOffset, int nSize);
};
class CCardFile
{
public :
int m_nSFID;
map<int, CCardRecord> m_records;
CCardFile() {}
CCardFile( int nSFID ) { m_nSFID = nSFID;}
};
class CCardObj
{
public:
CCardObj();
virtual ~CCardObj();
BOOL LoadCardMapping();
BOOL ReadMappingFile(CXMLReader &xml);
void XMLCardFile(CXMLReader &xml);
void XMLCardRecord( CXMLReader &xml );
void XMLCardData( CXMLReader &xml );
CString m_csTag;
int m_nSFID;
int m_nRecNo;
int m_nRecSize;
int m_nDataOffset;
int m_nDataType;
int m_nDataSize;
CString m_csName;
BYTE m_Data[29];
// CardReader Object - LOW LEVEL API
CCardReader* m_pCardReader;
// Associate stringwith SFID, RecNo, Offset and Size
map<CString, CDataIndex> m_dataIndex;
// File collection index by Short File Id (SFID)
map<int, CCardFile> m_FileIndex;
};
When I parse the XML file and I find the <CardRecord> tag I get its
attributes and I would like to add a new array of byte.
How can I do that ?
void CCardObj::XMLCardRecord( CXMLReader &xml )
{
xml.getAttribute( "index", m_nRecNo ); // Get record No
xml.getAttribute( "size", m_nRecSize );// Get record size
m_FileIndex[ m_nSFID ].m_records[ m_nRecNo ] = ????
xml.intoTag();
while ( xml.nextTag( m_csTag ) ){
if (m_csTag == "CardData"){
XMLCardData( xml );
}
}
xml.outofTag();
}
