( [id://3333]=superdoc: print w/replies, xml ) Need Help??
tada! now I work at the item level instead of it's parent:
use strict; use warnings; use Data::Rmap qw(:all); use Data::Dumper; my $initial_lol = [ note => [ shopping => [ item => 'sample' ] ] ]; # In $initial_lol, the new child of shopping is shopping_items my $new_lol = newnode($initial_lol, item => shopping_items()); warn Dumper($new_lol); sub newnode { my ($lol, $node_label, $new_node)=@_; my ($mapresult) = rmap_array { if ($_->[0] eq $node_label) { $_ = shopping_items(); cut($_); } else { $_; } } $lol; $mapresult; } sub shopping_items { my @shopping_items; for my $item qw(bread butter beans) { push @shopping_items, [ item => $item ]; } \@shopping_items; }




The mantra of every experienced web application developer is the same: thou shalt separate business logic from display. Ironically, almost all template engines allow violation of this separation principle, which is the very impetus for HTML template engine development.

-- Terence Parr, "Enforcing Strict Model View Separation in Template Engines"

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.
