Hi, Thanks a lot for the advice.
But , we cannot change the code, since we have one common code which parses the reg-exp and extracts the groups. So we want to write the reg-exp with nested groups.Each group extracted is the "Local interface " group. The attributes we want to collect from this group will be the subgroups. Is this possible using reg-exp ? We did the following : (Local interface: [\w\W\s]+VC ID: (\d+),[\w\W\s]+packet totals: receive (\d+), send (\d+)\s+byte totals:\s+receive (\d+), send (\d+)\s+packet drops:\s+ receive (\d+), send (\d+))+ With this, am able to extract only the last group. Any hints, ideas on how to proceed on this would be of great help.
