I am able to parse list. However, as there are two lists in one pattern, data related to only 2nd list is stores. pattern: (padding=[1,2,3,4],data = 1, size=[1,2]); The data related to first list gets overwritten. Can I use some context like if token is padding store data to one array and if token is size save data to another array. However, any suggestion is welcome. Best Regards, Archana Deshmukh [There are lots of ways to do this. You could set a flag when you see the padding or size token to say where to store the list. Or you could allocate space dynamically; put each list in a fixed static place as you parse it, then make a copy when you see the ] and return it. -John]
