well formed parentheses to .dot file

[szakos]

Hi all,

I want to generate a .dot file (to graphwiz) from well formed paretheses, but haven't figured yet how can I convert them.
example:

1  2  3  4  5  6
(  (   )  (   )  )
1  1  0  1  0  0
 
     1
    / \
   2  *7
  / \
*3  4
    /  \
  *5  *6

1  2  3  4  5  6
(  (   )  (   )  )
1  1  0  1  0  0

     1
    / \
   2  *7
  / \
*3  4
    /  \
  *5  *6

So the '('s mean 1s and they are nodes. ')' mean 0s and they are leaves. The order is preorder, if i am not wrong.
My question is, how create from 1100100 to 1--2, 2--*3, 2--4, 4--*5, 4--*6, 1--*7.
I see the left connections but not the right ones. Left (i,i+1), if i==1.
