Hi Gopi,
Accessing a context element or a context attribute requires to first have a  reference to the related context node. The context root node can be accessed by the standard attribute WD_CONTEXT. 
To Access a Node Element: After having accessed a context node, the reference to the element at lead selection  of this node can be obtained by calling the method get_element( ). Thismethod  returns a reference to the element instance of type IF_WD_CONTEXT_ELEMENT. Accessing the Node Element at Lead Selection  The element with index n can be accessed using the method get_element( index  = n ) .
Once we access the element we can access the attribute by GET_ATTRIBUTE().
Child nodes of the context root node can be identified using the get_child_node(  ) method. This method returns a reference to the node instance of type  IF_WD_CONTEXT_NODE. The get_child_node( ) method requires the name of  the node and, optionally, the index of the element in the parent node to which the  desired node instance belongs. In this case, the parent node is the context root,  which only ever has one element; therefore, the index parameter is 1 (default =  lead selection of parent element).
Best regards,
Suresh
