Usually it's easier to match what you want to keep instead of splitting on the stuff you don't want:
#!perl -w
use strict;
use Data::Dumper;
my $string=q{C*ID1*Mac*C release for EA's D*ID1*Spore1 game*D; D*ID1*S
+pore 1*D is better than D*ID2*Spore 2 game*D.};
my @sections;
while( $string =~ m!(([CD])\*(.*?)\*\2)!g) {
push @sections, $1;
};
print Dumper \@sections;
__END__
$VAR1 = [
'C*ID1*Mac*C',
'D*ID1*Spore1 game*D',
'D*ID1*Spore 1*D',
'D*ID2*Spore 2 game*D'
];
The regular expression looks for a C or D followed by a * and then slowly goes forward until it finds a * followed by whatever it matched at the start.

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).
