G'day Dimitar,
You can write a very simple function, to convert those (and other) entities back to their original characters, if that's what you need:
#!/usr/bin/env perl
use strict;
use warnings;
{
my %char_for_ent = qw{" " ' ' < < > >};
my $re = qr/(?x: ( @{[ join '|', keys %char_for_ent ]} ) )/;
sub ent2char { $_[0] =~ s/$re/$char_for_ent{$1}/g; $_[0] }
}
print "IN: ${_}OUT: ", ent2char($_) while <DATA>;
__DATA__
I said, "My name's Ken".
<pre>Here's some <em>emphasis</em>.</pre>
Output:
IN: I said, "My name's Ken".
OUT: I said, "My name's Ken".
IN: <pre>Here's some <em>emphasis</em>.</pre>
OUT: <pre>Here's some <em>emphasis</em>.</pre>
I suspect there may be a CPAN module with this functionality.
I don't know for certain: perhaps another monk does.

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.
