Your priority values are hashes. So how do you want to compare {'IS-ABC' => '3'} with {'IS-XYZ' => '3'}? Do you compare IS-ABC with IS-XYZ alphabetically, and what if they are equal?

From your desired output here's something that I think will work:

sub sortBySite { my ($site_a) = keys %{$tmp{$a}{'priority'}}; my ($site_b) = keys %{$tmp{$b}{'priority'}}; return $site_a cmp $site_b; }

Also, does your data really need to be stored as a HoH? Would this simpler structure work for you?

'hostX1-1-l.example.com' => { priority => 'IS-ABC', priority_level => 3, os => 'linux', pager => 'man-duty', }

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
