Very helpful. I was on my way of doing the same thing, but didn't see the needed container. If I were to try and get a unique list of all the values, does this make sense:
my $struct = {...}; # the hash of hashes in the question
my $found;
Data::Walk::walk \&wanted, $struct;
print join(" ",sort keys %$found) ,"\n";
sub wanted{
if (/^values$/){
foreach ( keys %{$Data::Walk::container->{$_}} ){
$found->{$_}=1;
}
}
}

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).
