hello ,
you can do something like the following
my $counter = -1;
foreach (@array){
$counter++;
if($_ =~m/$word/){
print "Element ID is $counter";}
}

Say, I find a elements contains the word I want by regular expression ($_ =~ /word1/), and then I need get the following element untill another words appears ($_ =~ /word2/). I thought the best way for me is to get the numeric index of the elements and get the elements i want. Do you have any suggestions?
