Default Parsing question:

I am an admitted perl newbie. So please be gentile I bruise easily. I have a very simple question for someone who actually knows perl as I stumble through it. I have a variable and I want to split/parse/seperate it into two variables. One taking all characters before the pipe "|" and the other taking all characters after the "|". For example here is what I have:

$inVar = " abc123 | 345 def ";

what I want to parse it out into is:

$outSplitVar1 = "abc123";
$outSplitVar2 = "345 def";

I want to trim off all leading and trailing spaces but retain any spaces in the middle. Any suggestions other than loop through character by character. I can do that but seek something simpler.

A humbly thank you in advance for any Perl Gods who are willing to waste their time to answer my sniveling unimportant trivial question.

Hey robprell

Sounds like you need to use regular expressions, list context and split. You can do a google for each of these things. Once you know them, you can do:

my $in = "  abc123   |   345 def   "; # initial thing to split
$in=~s/^\s+//; # strip leading spaces
$in=~s/\s+$//; # strip trailing spaces
my ($out1,$out2) = split /\|/,$in; # split string (nb \| is different to |)
print ">" . $out1 ."<\n>" . $out2 . "<\n" # print the results
Gives us:

>abc123   <
>   345 def<

Default Solution!!!

use warnings;

my $inVar = " abc123 | 345 def ";


foreach (@arr)
$_ =~ s/^[\s]* (.+\S) [\s]*$/$1/g;


foreach (@arr)
print "$_#######\n";
