Hi,

i have realized the snapshot is not visible in below mail.
*my objective* to set comments for each parameter name like <board_pos>,
clock_masters and all given below.
Please find the code snippet.

                       while (curr1 != end1)  // iterate second level map
                        {
                            // LOG("Section name [%s] : Parameter name and
value are [%s] -->
                            //
[%s]\n",curr->second.c_str(),curr1->first.c_str(),curr1->second.c_str());

                            ptParamVal.put("<xmlcomment>", "some comment");
                            ptParamVal.put((curr1->first).c_str(),
(curr1->second).c_str());

                            curr1++;
                        }
