Hi, I have a text file, from which I have parsed some strings like this : 

LB split2 1e38 split1 -0.43092 + (4.788 * W)  
M2 split2 L < 10 AND W < 1.080 split1 (-0.665364 + (9.6216 * W))*(10/L
+) split1 -1.38618 + (20.045 * W) split2(L < 10 AND W >= 1.080) OR (L 
+>= 10 AND W > 0)split1 -0.665364 + (9.6216 * W) split1 -1.38618 + (20
+.045 * W)  
M1 split2 L < 10 AND W < 1.080 split1 (-0.665364 + (9.6216 * W))*(10/L
+) split1 -1.38618 + (20.045 * W) split2(L < 10 AND W >= 1.080) OR (L 
+>= 10 AND W > 0)split1 -0.665364 + (9.6216 * W) split1 -1.38618 + (20
+.045 * W)

Now, I want to split this string and want to store it in nested hash..Like this 
%metals = (
#    $metal-level1 ==> {
#                LENGTH_RANGES ==> @length(L1,L2)
#            WIDTH_RANGES ==> @width(W1)
#                          EM_POLY ==> {

LB, M1 and M2 are metal lines and then I have width and length of metals and polynomial equations. I have extract all these values and stored in arrays, But as I am new to perl, So, I couldn't figured out that how can I store those values in 3D hash structure. I am using these keywords split1, split2 to split the string into different arrays for length, widths and so on.

I am not asking for a solution, but just an idea that how can I make a 3d hash structure for the given text. Thanks
