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.
