Hi 2 everyone. I need to parse some file into a hash, but the thing is that this file is a list, similar to this:

key1 value1

key2 value2

value3

vasue4

key3 value5

key4 value6

value7

key5

key6

As you can see quantity of possible keys and posiible values isn't matching. And on top of this I need following:

-If the key for a certain string doesn't exist previous value must be used

I mean:

key1 value1

key2 value2

key2 value3

key2 vasue4

If the value for certain string doesn't exist, it should be repalced with empty value:

key5 <empty>

key6 <empty>

So the resulting hash should be:

key1 value1

key2 value2

key2 value3

key2 vasue4

key3 value5

key4 value6

key4 value7

key5 empty

key6 empty

I hope someone can help me with this.

Thanks in advance, kazak.
