Escape HTML tags:
In structural HTML, the <b> tag should be replaced with <strong> and the
<i> tag with <em>.
Escape a code example:
<pre><code># Overload Apache::FakeRequest&#39;s print to append output to a variable.
{
no warnings &#39;redefine&#39;;
*Apache::FakeRequest::print = sub {
my $r = shift;
$Output .= join(&#39;&#39;, @_)
};
*Apache::FakeRequest::log_error = sub {
my $r - shift;
print STDERR @_, &quot;\n&quot;; $Errout .= join(&#39;&#39;, @_)
};
*Apache::FakeRequest::pnotes = sub {
my ( $r, $key ) = @_;
$Pnotes-&gt;{ $key } = shift if @_;
$Pnotes-&gt;{ $key };
};
}</code></pre>
