How to convert string to argument?

Question

Programming

Based on the question:
from this - "t1[t2][t3][1]"
to transform into this - t1[t2][t3][1]
string to turn into a non-string and non-number argument,
that is: a = t1[t2 ][t3][1] -- in this case the table can be found. The bottom line is that I want to record the path of the table, and then use it for recording or another purpose.

hm. parse into an array of 4 string elements using a regular expression and then do something like this:
this[arg[0]][arg[1]][arg[2]][arg[3]]
