hi friends,
i am able to parse the xml file and retrieve the corresponding tag values. Now how can i send the retrieved values from python function to the c functions.
And also can any one help me in retrieving all the sub tag values from a particular action tag.
I am very thankful for helping me.

Thanks and Regards,
siva.

c file:

#ifdef _DEBUG
  #undef _DEBUG
  #include "python.h"

    // Initialize the Python Interpreter
    Py_Initialize();

    // Build the name object
    pName = PyString_FromString(argv[1]);

    // Load the module object
    pModule = PyImport_Import(pName);

    // pDict is a borrowed reference 
    pDict = PyModule_GetDict(pModule);

    // pFunc is also a borrowed reference 
    pFunc = PyDict_GetItemString(pDict, argv[2]);

    if (PyCallable_Check(pFunc)) 
    {
        // Prepare the argument list for the call
        if( argc > 3 )
