Constructors

$i = HTML::Microformats::Datatype::Interval->new($span)

Creates a new HTML::Microformats::Datatype::Interval object.

$span is a DateTime::Span object.

$i = HTML::Microformats::Datatype::Interval->parse($string, $elem, $context)

Creates a new HTML::Microformats::Datatype::Interval object.

$string is an interval represented in ISO 8601 format, for example: '2010-01-01/P1Y' or '2010-01-01/2011-01-01'. $elem is the XML::LibXML::Element being parsed. $context is the document context.

This constructor supports a number of experimental microformat interval patterns. e.g.

<div class="interval">
 <span class="d">4</span> days starting from
 <abbr class="start" title="2010-01-01">2010</abbr>
</div>
