SO basically I have a file that looks like this

TCONS_00000047 XLOC_000039

TCONS_00000718 XLOC_000456

TCONS_00000938 XLOC_000610

TCONS_00004086 XLOC_002872

TCONS_00004252 XLOC_003003

TCONS_00004975 XLOC_003624

TCONS_00004976 XLOC_003624

TCONS_00005492 XLOC_004020

there are more like that . How do i declare a hash for all the keys and variables at once? This is what i did 

open(IN, $file)||die "Can not open file: $file\n";

%hash =( 'TCONS_00[0-9]+' => 'XLOC_[0-9]+');


@keys= keys %hash;
@values= values %hash;

print @keys;
print @values;

close(IN);

The hash took the key as a string, not a regex operation. What can i do?
