Given a data structure like this ...
$oWkBook = {
students =>[
{fname=>'joe',lname=>'bloe',age=>'18'},
{fname=>'jill',lname=>'bill',age=>'16'},
],
teachers => [
{fname=>'joe',lname=>'sloe',age=>'38'},
{fname=>'jill',lname=>'sill',age=>'36'},
],
admins =>[
{fname=>'koe',lname=>'moe',age=>'58'},
{fname=>'dill',lname=>'mill',age=>'56'},
],
};
How can I change this ...
### iterate (current)
for my $oWkSheet (keys %{$oWkBook}){
for my $oRec (@{$oWkBook->{$oWkSheet}}){
for my $oFld (keys %{$oRec}){
$oRec->{$oFld} =~ s/^\s+\n$//;
};
};
};
into this ...
### iterate (wanted)
for my $item ($oWkBook->iterate_fields()){
$item =~ s/^\s+\n$//;
};
I've given SuperSearch a say, but it seems the examples
assume a simple sequence of items (e.g. array), when what I want to
do is iterate over an arbitrarily-nested data structure. (e.g. HoAoH)
My long term goal is to be able to reproduce this pattern regardless of the structure of the data variable. The request here is for a link or an example of handling HoAoH with iterators that I can use as a starting point for understanding this design pattern a little better.

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).
