> (separate parsing...semantic logic). What do you mean with that? 

Your two examples seem to hold the same information (semantic) while having different format (syntax).

So better write parsers for the different formats which "cache" them in an intermediate format. These parsers should be ignorant about the meaning just concentrating on correctness.

The semantics - the meaning of the data - could be handled by one central module which only operates on the intermediate format. This module could be reused for all formats.

A possible intermediate format could be nested hashes

$cache = {
    ObjectType1 => { 
        Param1 => 8,
        Param2 => "SomeText",
        NestedObject => { 
            Param1 => 3,
            Param2 => "SomeText"
        } 
}

Of course this highly depends on the nature of your data, like

Using nested arrays may be better then°

And after transforming your data you can also have emitter modules to write them into a new out file.

Like this you are even capable to transform between different formats, or add new ones.

HTH! :)

edit

NB: this approach is also useful when handling only one input format, because you can cleanly separate code, hence much better maintain it.
