Hello,
I am facing a problem in using regular expression on array. My code is
written below:
Hi -
I don't think you can regex on a whole array; try this
after you have loaded the array:
for (@lines) {print ok if /Date:/; }
This iterates the array lines presenting $_ for each
iteration. The regex /Date:/ operates on $_.

Don't know if you can do a search on an array (until and unless you want to evaluate
each element)
In case you are trying to achieve the multiple lines search, maybe this or the 2nd
example can help :
open (FILE , $ARGV[0]);
my @lines = FILE;
close(FILE);
$line = join( , @lines);

Beau..I guess , the evaluation of the expression is not going to be true if
no Date: is found. Since map returns a list consisting of the results of
each successive evaluation of the expression..., the map will return undef.
Although, here..I
