NAME
       PPIx::Utilities::Node - Extensions to PPI::Node.

VERSION
       This document describes PPIx::Utilities::Node version 1.1.0.

SYNOPSIS
	   use PPIx::Utilities::Node qw< split_ppi_node_by_namespace >;

	   my $dom = PPI::Document->new("...");

	   while (
	       my ($namespace, $sub_doms) = each split_ppi_node_by_namespace($dom)
	   ) {
	       foreach my $sub_dom ( @{$sub_doms} ) {
		   ...
	       }
	   }

DESCRIPTION
       This is a collection of functions for dealing with PPI::Nodes.

INTERFACE
       Nothing is exported by default.

   split_ppi_node_by_namespace($node)
       Returns the sub-trees for each namespace in the node as a reference to a hash of
       references to arrays of PPI::Nodes.  Say we've got the following code:

	   #!perl

	   my $x = blah();

	   package Foo;

	   my $y = blah_blah();

	   {
	       say 'Whee!';

	       package Bar;

	       something();
	   }

	   thingy();

	   package Baz;

	   da_da_da();

	   package Foo;

	   foreach ( blrfl() ) {
	       ...
	   }

       Calling this function on a PPI::Document for the above returns a value that looks like
       this, using multi-line string literals for the actual code parts instead of PPI trees to
       make this easier to read:

	   {
	       main    => [
		   q<
		       #!perl

		       my $x = blah();
		   >,
	       ],
	       Foo     => [
		   q<
		       package Foo;

		       my $y = blah_blah();

		       {
			   say 'Whee!';

		       }

		       thingy();
		   >,
		   q<
		       package Foo;

		       foreach ( blrfl() ) {
			   ...
		       }
		   >,
	       ],
	       Bar     => [
		   q<
		       package Bar;

		       something();
		   >,
	       ],
	       Baz     => [
		   q<
		       package Baz;

		       da_da_da();
		   >,
	       ],
	   }

       Note that the return value contains copies of the original nodes, and not the original
       nodes themselves due to the need to handle namespaces that are not file-scoped.	(Notice
       how the first element for "Foo" above differs from the original code.)
