Wow! Most excellent!
Just a small addition, I think there is a missing ")" which I added below..right there at the tail-end ")/g". I also changed this to put the tokens directly into an array without the need for "while".
#!/usr/bin/perl -w
use strict;
my $line = "2006-01-01,Kims,Watson,406,560(centrifuge, refrig.),569,60
+7(dark room),210-211,101(ultracentrifuge),104-105(crystal growth room
+s),660(centrifuge, refrig.)";
my @tokens = $line =~ m/([^,(]+(?:\([^)]*\))?)/g;
foreach my $token (@tokens)
{
print "$token\n";
}
__END__
Prints:
2006-01-01
Kims
Watson
406
560(centrifuge, refrig.)
569
607(dark room)
210-211
101(ultracentrifuge)
104-105(crystal growth rooms)
660(centrifuge, refrig.)
Update: the only other small refinement would be to add () around the match-global to make it super clear that this is list context:
my @tokens = ($line =~ m/([^,(]+(?:\([^)]*\))?)/g);

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).
