I know that it this is not hard to write by myself, but
in order to avoid reinventing the wheel: Does someone know a CPAN utility module, which has a function to create a subset of a hash, so that the newly created hash contains only those keys of the original hash which match a certain regexp? Kind of
my %new_hash=();
grep {
$_ =~ $my_regexp && $new_hash{$_}=$original_hash($_)
} keys %original_hash;

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).
