NAME

       Pod::Elemental::Transformer::Gatherer - gather related paragraphs under a shared header

VERSION

       version 0.102362

OVERVIEW

       Like the Nester transformer, this Gatherer produces structure and containment in a Pod document.  Unlike that Nester, it does not find top-
       level elements, but instead produces them.

       It looks for all elements matching the "gather_selector".  They are removed from the node.  In the place of the first found element, the
       "container" node is placed into the transformed node, and all the gathered elements are made children of the container.

       So, given this document:

	 Document
	   =head1 Foo
	   =over 4
	   =item * xyzzy
	   =item * abcdef
	   =back
	   =head1 Bar
	   =over 4
	   =item * 1234
	   =item * 8765
	   =back

       ...and this nester...

	 my $gatherer = Pod::Elemental::Transformer::Gatherer->new({
	   gather_selector => s_command( [ qw(over item back) ] ),
	   container	   => Pod::Elemental::Element::Pod5::Command->new({
	     command => 'head1',
	     content => "LISTS
",
	   }),
	 });

       Then this:

	 $nester->transform_node($document);

       Will result in this document:

	 Document
	   =head1 Foo
	   =head1 LISTS
	     =over 4
	     =item * xyzzy
	     =item * abcdef
	     =back
	     =over 4
	     =item * 1234
	     =item * 8765
	     =back
	   =head1 Bar

ATTRIBUTES

   gather_selector
       This is a coderef (a predicate) used to find the paragraphs to gather up.

   container
       This is a Pod::Elemental::Node that will be inserted into the node, containing all gathered elements.
