NAME

HTML::Microformats::Utilities - utility functions for searching and manipulating HTML

DESCRIPTION

This module includes a few functions for searching and manipulating HTML trees.

"searchClass($class, $node, [$prefix])"

Returns a list of elements which are descendents of $node and have class name $class.

$class can be a plain string, or a regular expression.

If $prefix is supplied it is used as an optional prefix for $class. For example, with $class 'bar' and $prefix 'foo', searchClass will look for all of the following classes: 'bar', 'foobar', 'foo-bar' and 'foo:bar'.

"searchAncestorClass($class, $node, [$skip])"

Returns the first element which is an ancestor of $node having class name $class.

$class can be a plain string, or a regular expression.

$skip is the number of levels of ancestor to skip. If $skip is 0, then potentially searchAncestorClass will return $node itself. If $skip is 1, then it will not return $node but could potentially return its parent, and so on.

"searchRel($relationship, $node)"

Returns a list of elements which are descendents of $node and have relationship $relationship.

$relationship can be a plain string, or a regular expression.

"searchRev($relationship, $node)"

As per searchRel, but uses the rev attribute.

"searchID($id, $node)"

Returns a descendent of $node with id attribute $id, or undef.

"searchAncestorTag($tagname, $node)"

Returns the nearest ancestor of $node with tag name $tagname, or undef.

"stringify($node, \%options)"

Returns a stringified version of a DOM element. This is conceptually equivalent to "$node->textContent", but follows microformat-specific stringification rules, including value excerption, the abbr pattern and so on.

"xml_stringify($node)"

Returns an XML serialisation of a DOM element. This is conceptually equivalent to "$node->toStringEC14N", but hides certain attributes which HTML::Microformats::DocumentContext adds for internal processing.
