Need to read file in double loop

[Tong Sun]

Hi, 

I need to read file in double loop -- 

- reading file line by line until a special KW is met, say "S"

- When it happens, need to collect content line by line until another special KW is met, say "E"

For e.g., if processing the following content line by line, then the content from S 3 till 6 E need to be processed as a *single group*:

1

2

S

3

4

5

6

E

7

8

9

How can I do that?

I've prepared a starter

https://play.golang.org/p/brdLtyjt-L2

but it is not working as I expected

Why 7 8 9 are not processed?

How to fix it?

Thx!

You should start by asking yourself why your program outputs "1", "2" and "S". Hint: after seeing "S" you don't break out of the inner loop until another "S" is seen which your sample data does not include.

That's a typo. Changing it to "E" you'd think the problem is solved?

Ops. sorry, it is. Wonder why it wasn't working before (tried at least twice).
