NAME
HTML::Microformats::DocumentContext - context for microformat objects
DESCRIPTION
Microformat objects need context when being parsed to properly make sense. For example, a base URI is needed to resolve relative URI
references, and a full copy of the DOM tree is needed to implement the include pattern.
Constructor
"$context = HTML::Microformats::DocumentContext->new($dom, $baseuri)"
Creates a new context from a DOM document and a base URI.
$dom will be modified, so if you care about keeping it pristine, make a clone first.
Public Methods
"$context->cache"
A Microformat cache for the context. This prevents the same microformat object from being parsed and reparsed - e.g. an adr parsed
first in its own right, and later as a child of an hCard.
"$context->document"
Return the modified DOM document.
"$context->uri( [$relative_reference] )"
Called without a parameter, returns the context's base URI.
Called with a parameter, resolves the URI reference relative to the base URI.
"$context->document_uri"
Returns a URI representing the document itself. (Usually the same as the base URI.)
"$context->make_bnode( [$element] )"
Mint a blank node identifier or a URI.
If an element is passed, this may be used to construct a URI in some way.
"$context->profiles"
A list of profile URIs declared by the document.
"$context->has_profile(@profiles)"
Returns true iff any of the profiles in the array are declared by the document.
"$context->add_profile(@profiles)"
Declare these additional profiles.
"$context->representative_hcard"
Returns the hCard for the person that is "represented by" the page (in the XFN sense), or undef if no suitable hCard could be found
"$context->representative_person_id( [$as_trine] )"
Equivalent to calling "$context->representative_hcard->id($as_trine, 'holder')", however magically works even if
$context->representative_hcard returns undef.
"$context->contact_hcard"
Returns the hCard for the contact person for the page, or undef if none can be found.
hCards are considered potential contact hCards if they are contained within an HTML <address> tag, or their root element is an
<address> tag. If there are several such hCards, then the one in the shallowest <address> tag is used; if there are several <address>
tags equally shallow, the first is used.
"$context->contact_person_id( [$as_trine] )"
Equivalent to calling "$context->contact_hcard->id($as_trine, 'holder')", however magically works even if $context->contact_hcard
returns undef.
