Question

Hi Friends,
See the followong code which converts xml data into itab.

*PURPOSE: This program transfers XML data into SAP internal table format
*The nodes in DOM can be stored as fields in SAP Internal table

in the above code at line no: 268 there is a method:
value = node->get_value( ).in which actual data from XML file is coming.
So the varibale "Value" contains the data.
see line no: 270:
WRITE: AT indent value COLOR COL_GROUP INVERSE.
what ever values i am getting here i want to append to a Internal table ...
Can any body tell me how to do that?
i am sure of reward points.
