~~, the Smatch Match Operator introduced in Perl 5.10 and already mentioned by JavaFan is probably the best thing for you. See Smart matching in detail in the Perl documentation for more details.
It only works in Perl 5.10 and later. If you are using an earlier version, you should consider upgrading.
If you can't upgrade, grep and the functions in List::Util and List::MoreUtil may do what you need. Note that grep has a performance price, as it always goes over the entire list, but on small lists it's not significant.

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).

or How to display code and escape characters
are good places to start.
