Hmmm, as Corion has pointed out, you'll get much better response by showing what you have tried, and in what way it fails.
That being said, does this code do what you are looking for?
use strict;
use warnings;
my $str = "*L*Name1*L*Name2*L**D*Place1*D*Place2*D**L*Name3*L*";
my @names =$str =~ m/\*L\*(\w+)/g;
print "@names\n";
$str =~ s/\*L\*$names[0]//;
print "Modified string = $str\n";
Output:
Name1 Name2 Name3
Modified string = *L*Name2*L**D*Place1*D*Place2*D**L*Name3*L*

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
