    Hi NisHera ,

     

    Thanks for the reply.The function will get attribute name value (MarkXX_Gas_1.22_Fwd_Win7) using project variable . using that value select the configuration whose attribute name value is similiar to passed value and then read all other attribute values.
    after that read the child node Meters and its sub child and attribute values. 

    I have to specifically use selectSingleNode().
