how to use grep to match elements of an array

[Noah]

Hi there,

I am trying to figure out how to use grep in a particular situation.
The line is:
        next unless grep ($fromdevice, @sitenamekeys);


but I am not quite matching properly.

@sitenamekeys = /ABC DEF GHI/;

and $fromdevice could be something like "device1.abc" or "device2.def"
basically I am trying to get the grep to identify if the current 
$fromdevice has anything that matching any of the elements in @sitenamekeys

So "device1.abc" or "device2.def" would be a match and therefore would 
continue without next but something like "device1.xyz" would not match 
and therefore next would be executed.

Any help is appreciated.

Cheers,

Noah
