NAME

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

SYNOPSIS

 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);

DESCRIPTION

"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.
