Code: XML Serializer

What the Code Does

This is a set of macros and a class for serializing and deserializing XML files and XML buffer in C++. The serializer uses an ATL String and ATL collections. It provides object representation of XML files and means to store and load objects to and from XML. This is something similar to the XmlSerializer option in C#, but becausee there is no reflection option with C++, one has to write the classes representing XML. This code is developed in VS 2005.

Simple Example

Start with a simple XML code.

Step 1: Creating a class representation

class CEmployee
{
public:
   CAtlString m_csName;
   DWORD      m_dwAge;

};

Step 2: Making the above class serializable

Make the above class serializable, as shown here:

class CEmployee
{
public:
   CAtlString m_csName;
   DWORD      m_dwAge;

   DECLARE_XML_MAP("employee")
};

BEGIN_XML_MAP(CEmployee)
   XML_STR_ATTRIBUTE("name",m_csName)
   XML_DWORD_OBJECT ("age", m_dwAge)
END_XML_MAP()

Step 3: Loading and storing XML

Load and store the XML in this manner:

CEmployee oEmployee;
oEmployee.m_csName= L"xyz";
oEmployee.m_dwAge = 25;

CXmlSerializer<CEmployee>::Serialize( L"c:\\emp.xml", oEmployee);

CEmployee oLoadedEmployee;
CXmlSerializer<CEmployee>::Deserialize(
L"c:\\emp.xml", oLoadedEmployee):
