$category->term('joke');
$category->scheme('http://example.org/extra-cats/');

DESCRIPTION

Category Documents contain lists of categories described using the ``atom:category'' element from the Atom Syndication Format [RFC4287].

The Category Document is defined in ``The Atom Publishing Protocol,'' IETF Internet-Draft.

METHODS

XML::Atom::Categories->new([ $stream ])

Creates a new Category Document object, and if $stream is supplied, fills it with the data specified by $stream.

Automatically handles autodiscovery if $stream is a URI (see below).

Returns the new XML::Atom::Categories object. On failure, returns "undef".

$stream can be any one of the following:

  • Reference to a scalar

    This is treated as the XML body of the Category Document.

  • Scalar

    This is treated as the name of a file containing the Category Document XML.

  • Filehandle

    This is treated as an open filehandle from which the Category Document XML can be read.

  • URI object

    This is treated as a URI, and the Category Document XML will be retrieved from the URI.

$categories->categoryk([ $category ])

If called in scalar context, returns an XML::Atom::Category object corresponding to the first ``app:category'' element found in the Category Document.

If called in list context, returns a list of XML::Atom::Category objects corresponding to all of the ``app:category'' elements found in the Service Document.

$service->add_category($category)

Adds the category $category, which must be an XML::Atom::Category object, to the Service Document as a new ``app:category'' element. For example: 

    my $category = XML::Atom::Category->new;
    $category->term('joke');
    $categories->add_category($category);

$categories->fixed

$categories->scheme

$categories->href

$categories->element_name

$categories->element_ns
