Problems with Array

[dgallig]

Hello everybody ,
I have a problem with arrays ...
I need to get some data from files in some directories .

The names of the dirs are something like 12.12344 or 23.34441.
Some contains one , some 2 or 3 files .

I'd like to get data from those dirs recursively ... but dunno how .

I've tried something like :

@DIR=("12.12344","23.34441");
@12.12344=("height","width");
@23.34441=("height");

and then reading with 2 nested foreach :

foreach $directory (@DIR) {
foreach $element ($[@directory]){ <- this is wrong I know , but how can i do something like this ??

1) I can't use the "." in the name of the array
2) Dunno how to use the variable name as the name of the array ...


I tried even with something like :

%DIR=("12.12344","height",
"23.34441","height",
"12.12344","width")

and using :
while (($directory, $element) = each(%DIR)){

but isn't working either , seems because the keys are repeated .

Maybe it's a stupid problem , I know , but this is my first
try in Perl ( Yes , I' m a total noob )

Someone can help ?

Thx in advance

David

or

Thx travs69
but i have this problem ...
Those dirs all contains a lot of files and subdirs ,
and when not needed some files in the dirs have "fakes" values
i don't want t read .
Example :
dir 12.6567 has a "height" file which contains a value i want
to read and a "width" file which contains a value that is normal in all respects but is fake , and I'm not interested in reading it ...
Dunno if I have explained it well , or now is worst than before ...

how can you tell that the width value is a fake?

Because could be far too big or far too low ... but something
in the middle and reasonable too sometimes ... It's completely random . So can trick the scripts ...
