Do you still think that you have to perform this
task with one regular expression? (and a horribly,
unreadable, broken one at that.)
split is
perfectly cabable of stopping after it finds the, say, 3rd
element. Then you can do something different with the rest:
use Data::Dumper;
my $foo = 'one,123,a s d f,a,b,c,bad,e,f,g,h';
my @first = split(',',$foo,4);
my @rest = split(',',pop @first);
print Dumper \@first, \@rest;
for (0..$#rest) {
die "index $_ is bad: '$rest[$_]'" if length($rest[$_]) != 1;
}
Think in chunks. Don't try to swallow the whole pill at
once.

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).
