I agree with the prior replies... I'm not exactly sure what you are looking for... I tried out your code on a fairly simple example and it seems to work fine:
#!/usr/bin/perl -w
use strict;
my $e = '\\'; # kind of escape char
my $s = '\''; # this is a string to use for splitting
my $str = "this \n contains \\'\n new lines " .
"and single'\nquotes'\n more than\' once";
if( $str =~ m#$/# ) {
$s .= "$/"; # ?? right so?
}
my $re = qr/(?<!\Q$e\E)\Q$s\E/;
my @parts = split $re, $str;
print scalar(@parts), "\n";
for ( my $i = 0 ; $i < @parts ; $i++ ) {
print "$i: $parts[$i]\n";
}
gives the following output:
% ./test.pl
3
0: this
contains \'
new lines and single
1: quotes
2: more than' once
The string was split on '\n, but not \'\n, \n or '.

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).
