Pod::Elemental is a system for treating a Pod (plain old documentation) documents as trees of elements. This model may be familiar from many other document systems, especially the HTML DOM. Pod::Elemental's document object model is much less sophisticated than the HTML DOM, but still makes a lot of document transformations easy.
In general, you'll want to read in a Pod document and then perform a number of prepackaged transformations on it. The most common of these will be the Pod5 transformation, which assumes that the basic meaning of Pod commands described in the Perl 5 documentation hold:
=for commands mark regions of the document, leading whitespace marks a verbatim paragraph, and so on. The Pod5 transformer also eliminates the need to track elements representing vertical whitespace.
The event reader (by default a new instance of Pod::Eventual::Simple is used to convert input into an event stream. In general, it should provide
read_* methods that behave like Pod::Eventual::Simple.
The objectifier (by default a new Pod::Elemental::Objectifier) must provide an
objectify_events method that converts Pod events into Pod::Elemental::Element objects.
This is the class for documents created by reading pod.
These methods read the given input and return a Pod::Elemental::Document.
