Re: How to remove unwanted text from elements of an array?

Suitable code would use some method of iterating over the first array (perhaps map) and applying the substitution operator s/// to remove the unwanted text from each.

Suggest some suitable code for it.
Hmmm... looks like a problem that is good to learn
Perl from. What have you tried?

I downvoted this node for two reasons: 1. Your question wasn't clear (What are you trying to do?) and 2. Your post showed no effort (What have you tried?).
If you're trying to generation @array from @array1, then
@array = map { "INVITE:$_" } @array1;
would do the trick (although I have not tested it).
But really, it's hard to tell, based on how vaguely your post was worded.

This is such a simple question that I have to ask, are you serious about learning Perl, or do you just want the answer to turn in so you get a pass in your class?
If it were me, and I were in your position, I would pull out the documentation for split and map, or split and perlsyn, which discusses foreach loops. The foreach method would probably require push also.
Here's a map solution. I sincerely hope that I'm not giving you a homework answer.
my @array = qw/INVITE:Contact INVITE:To INVITE:From/;
my @new_array = map { ( split /:/ )[1] } @array;

I agree, give it your best shot, and then we'll be happy to critique. I feel I am not as smart as a lot of the other people on here and I don't understand your question very well. If you were to rephrase it, and add some code that represents your "best guess" as to how to do it, even if it's pseudocode, I would be much better equipped to try to help you. The code alone might give me a better idea of what you're trying to accomplish.

How about:

# that didn't work: @array1 = map { s/INVITE:// } @array;
@array1 = @array;
$_ =~ s/INVITE:// foreach @array1; # that works...

That modifies the elements of @array, leaving the results of the substitution (success or not) in @array1.

# that didn't work: @array1 = map { s/INVITE:// } @array;
In the code above you collect results of s/// operator, i.e. number of successful substitutions, which is not what you want. You want the content of $_ after substitution. And thus, you have to do this instead:
@array1 = map { s/INVITE://; $_ } @array;
... which indeed does work quiet nicely :)

Update: expanded explanation about return value of s/// operator.

You should really make an effort to solve the problem yourself. Take a look at How (Not) To Ask A Question and also How do I post a question effectively? as well. Although you probably didn't intend it, your final sentence sounds like a demand, and not like a request.
"Suggest some suitable code for it".
Perhaps asking a question would have worked better: Can anyone suggest some suitable code?
