Hello Monks

I am having some difficulty parsing back out the data contained in a hash reference. I am looking to print the data that I have passed in the reference. I can do it with Dumper but that's it.

I would REALLY like a pointer to the perl books on where this is covered. I need to bookmark it.

use strict;
use Data::Dumper;

my $names = &getNames;

my $valid_names = &validateNames(\$names);

sub getNames {

  my %data; 
  $data{'SCM555'}{'name'}='foo';
  $data{'SCM555'}{'email'}='foo@bar.com';
  $data{'SCM556'}{'name'}='foo2';
  $data{'SCM556'}{'email'}='foo2@bary.com'; 
  return \%data;
}

sub validateNames{ 
  my $valid_names=shift; 
  print Dumper($valid_names); 
  # I want to access ( print ) the data here

}

• 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).
