DESCRIPTION

XML::Atom::Syndication::Feed element is the document (i.e., top-level) element of an Atom Feed Document, acting as a container for metadata and data associated with the feed. Its element children consist of metadata elements followed by zero or more entry child elements.

METHODS

XML::Atom::Syndication::Feed is a subclass of XML::Atom::Syndication::Object (via XML::Atom::Syndication:::Thing) that it inherits numerous methods from. You should already be familiar with this base class before proceeding.

Class->new(%params)

In addition to the keys recognized by its superclass (XML::Atom::Syndication::Object) this class recognizes a Stream element. The value of this element can be a SCALAR or FILEHANDLE (GLOB) to a valid Atom document. The Stream element takes precedence over the standard Elem element.

inner_atom($atom_markup_string)

This is a convenience method for quickly setting the child Atom elements of the feed with a string. The string must also be well-formed XML. This method will replaces any existing child elements. All elements are presumed to be in the same Atom namespace as the feed object.

This method is similar to the innerHTML property found in JavaScript.
