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.
