So what you need is an arbitrarily nested hash searcher? Yikes, those can get tricky. See ref, but I'd start out with (pseudo) code like the following:
sub find_value {
my $hash_ref = shift;
my $level;
foreach my $key (keys %$hash_ref) {
$level .= "$key\n";
my $value = $hash_ref->{$key};
if (ref($value) eq 'HASH') {
$level .= find_value($value);
} else {
$level .= "\t$value\n";
}
}
return $level;
}
That's untested, and it doesn't do anything that Data::Dumper doesn't do better... but it's a place to start.

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).
