The XML parser uses a callback mechanism to parse an XML configuration file. The callback function receives the complete tree and uses macros to parse it. The macros perform a recursive call to the callback function to walk through the tree

The format of the callback function using these macros is:

int raePLUG_PARSER(raeXML_PARM)
{
  GET_NEXT_ELEMENT;
    IF_ELEMENT("Element_name")
    {
      WHILE_ATTR_LIST
       {
        IF_ATTR("Attribute")
        {
          GET_ATTR(attr_value);
          {
            Process attr_value ...
          }
        }
      }
      GET_DATA(data_value);
      Process data_value ...
    }
  GET_NEXT_NODE(status);
}
