in thread XML::Rules: Can hierarchy be changed?

sub { $_[1]->{text} = $_[1]->{_content}, delete $_[1]->{_content}, ret +urn ($_[0] => [$_[1]] , [$_[0] => $_[1]])}
is better written as
sub { $_[1]->{text} = $_[1]->{_content}; delete $_[1]->{_content}; ret +urn ($_[0] => [$_[1]] , [$_[0] => $_[1]])}
You can put several statements into an anonymous subroutine so no need to use commas where you mean semicolons :-)

Enoch was right!

Node Status?
node history
Node Type: note [id://862761]
[oiskuu]: You want to draw the path? $iter = combinations( $TOP_HEIGHT .. $NODE_HEIGHT, $pos); then get the path from the iter, level change at depth x, for(..) $pos += $level_change; something like that
[oiskuu]: yergh, <code> tags... [$top_height .. $node_height]
[Eily]: Discipulus by demonstrate I suppose you mean simulate with perl?
[Eily]: the demonstration itself is fairly easy. The number of paths on a node is the sum of the numbers of paths to the two nodes above (or one node above on the edges of the triangle)
[Eily]: since the value of a node is also the sum from the two nodes above, you just have to demonstrate that the equality is true at the top of the triangle
[Discipulus]: yes Eily, thanks oiskuu but i dont get it.. ;=( maybe I'll ask a SOPW
[LanX]: all combinations with same amount of left and right?
[Eily]: if you want to store in a structure with the coordinates as key, arrays might do, since the keys are going to be 0..n
[LanX]: (Pascale path)
