       XML::Grove::IDs - return an index of `id' attributes in a grove

	use XML::Grove::IDs;

	# Using get_ids method on XML::Grove::Document or XML::Grove::Element:
	$hash = $grove_object->get_ids($attr_name, $elements);

	# Using an XML::Grove::IDs instance:
	$indexer = XML::Grove::IDs->new($attr_name, $elements);
	my $hash = {};
	$grove_object->accept($indexer, $hash);

       "XML::Grove::IDs" returns a hash index of all nodes in a grove with an `id' attribute.
       The keys of the hash are the ID attribute value and the value at that key is the element.
       `$attr_name' and `$elements' are optional.  The attribute name defaults to `"id"' if
       `$attr_name' is not supplied.  Indexing can be restricted to only certain elements, by
       name, by providing a hash containing NAME=>1 values.
