If your hash is all you show us, you can simply say: my %newhash = (
accesslevels => {
func1 => $oldhash{function}{func1}{content},
default => $oldhash{function}{default}{content}
}
);
But if it is more generic (which I'm guessing it is), a possible approach can be: my %newhash;
foreach my $key1 (keys %oldhash) {
foreach my $key2 (keys %{$oldhash{$key1}}) {
foreach my $key3 (keys %{$oldhash{$key1}{$key2}}) {
$newhash{$key1}{$key3} = $oldhash{$key1}{$key2}{$key3}{con
+tent}
}
}
}

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).
