G'day mariaprabudass,

Welcome to the Monastery.

The output I get is 'Hello\'; not the '"**Hello**"' you show.

What you actually want to split on is a pipe (|) that is not preceded by a backslash (\). You can do this with, what is called, a negative look-behind assertion which looks like: (?<!PATTERN). See "perlre: Extended Patterns" for more details.

Both the pipe and backslash characters are special in regexes and need to be escaped. This gives a split pattern of /(?<!\\)\|/.

Here's my test code:

#!/usr/bin/env perl -l

use strict;
use warnings;

my $id = 'Hi|Hello\|Sir';
my @code = split /\|/, $id;
print $code[1]; 

@code = split /(?<!\\)\|/, $id;
print $code[1];

Output:

Hello\
Hello\|Sir
