Overview

HTML::Microformats::Format::XOXO inherits from HTML::Microformats::Format. See the base class definition for a description of property getter/setter methods, constructors, etc.

Unlike most of the modules in the HTML::Microformats suite, the "data" method returns an HTML::Microformats::Format::XOXO::UL, HTML::Microformats::Format::XOXO::OL or HTML::Microformats::Format::XOXO::DL object, rather than a plain hashref.

HTML::Microformats::Format::XOXO::DL

Represents an HTML DL element.

"$dl->get_values($key)": Treating a DL as a key-value structure, returns a list of values for a given key. Each value is an HTML::Microformats::Format::XOXO::DD object.

"$dl->as_hash": Returns a hash of keys pointing to arrayrefs of values, where each value is an HTML::Microformats::Format::XOXO::DD object.

"$dl->as_array": Logically what you think get_values("*") might do.

HTML::Microformats::Format::XOXO::UL

Represents an HTML UL element.

"$ul->as_array": Returns an array of values, where each is a HTML::Microformats::Format::XOXO::LI object.

HTML::Microformats::Format::XOXO::OL

Represents an HTML OL element.

"$ol->as_array": Returns an array of values, where each is a HTML::Microformats::Format::XOXO::LI object.

HTML::Microformats::Format::XOXO::LI

Represents an HTML LI element.

"$li->get_link_href": Returns the URL linked to by the first link found within the item.

"$li->get_link_rel": Returns the value of the rel attribute of the first link found within the item. This is an unparsed string.

"$li->get_link_type": Returns the value of the type attribute of the first link found within the item. This is an unparsed string.

"$li->get_link_title": Returns the value of the rel attribute of the first link found within the item if present; the link text otherwise.

"$li->get_text": Returns the value of the text in the LI element except for the first DL element within the LI, and the first UL or OL element.

"$li->get_html": Returns the HTML code in the LI element except for the first DL element within the LI, and the first UL or OL element.

"$li->get_properties": Returns an HTML::Microformats::Format::XOXO::DL object representing the first DL element within the LI.

"$li->get_children": Returns an HTML::Microformats::Format::XOXO::OL or HTML::Microformats::Format::XOXO::UL object representing the first OL or UL element within the LI.

"$li->get_value($key)": A shortcut for "$li->get_properties->get_values($key)".

HTML::Microformats::Format::XOXO::DD

This has an identical interface to HTML::Microformats::Format::XOXO::LI.

Microformat

HTML::Microformats::Format::XOXO supports XOXO as described at <http://microformats.org/wiki/xoxo>.

RDF output

XOXO does not map especially naturally to RDF, so this module returns the data as a JSON literal using the property <http://open.vocab.org/terms/json>.
