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 feed.
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 <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 <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 <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
