The sort function takes an optional customised sort routine wherin you compare aspects of $a and $b. perldoc -f sort.
my %HoH = (
SUB1 => {
Test1 => {
value1 => "2300",
value2 => "0.01",
},
Test2 => {
value1 => "5000",
value1 => "0.34",
},
},
SUB2 => {
Test1 => {
value1 => "2800",
value2 => "0.05",
},
},
);
for my $sub_key (sort {$HoH{$a}{Test1}{value1} <=> $HoH{$b}{Test1}{val
+ue1} }keys %HoH){
print "$HoH{$sub_key}{Test1}{value1}\n";
}
EDIT: Corrected inline sort routine, original post made pre-coffee and shower :)
print "Good ",qw(night morning afternoon evening)[(localtime)[2]/6]," fellow monks."

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.
