I want to build a tree like this:
$self->{tree}
|
-- node1
| |
| -- @children[ node3, node4]
|
-- node2
|
-- @children[node5, node6]
I thought adding node3 as a child of node1 would be
my $var = 'node1'
push( @{ $self->{tree}->{$var}->{'children'} }, 'node3');
put I keep getting
Can't use string ("node1") as a HASH ref yada yada yada
Suggestions?
