It's a META-LANGUAGE PROBLEM!! Everyone DUCK!!! ............................ quack, quack
Here's a third way of quoting that, unlike ' and " completely disables
the special properties of \.
It's a version of a "here-document" and it's documented in perlop.
#!/usr/bin/perl
use strict; # https://perlmonks.org/?node_id=11116857
use warnings;
my $text = <<'END'; # this quoting method disables special properties
+of \
1,Something\,\\text\\text\0x2B,X,99,\,\\,\\\,foobar
END
chomp $text;
print "input:\n$text\n";
my @fields = split /(?<!\\),|(?<=\\\\),/, $text;
print "\noutput:\n";
for ( @fields )
{
print "$_\n";
}
Outputs:
input:
1,Something\,\\text\\text\0x2B,X,99,\,\\,\\\,foobar
output:
1
Something\,\\text\\text\0x2B
X
99
\,\\
\\\
foobar
Is this output a correct solution to your problem?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
