7

SYNOPSIS

9        use XML::Grove::IDs;
10
11        # Using get_ids method on XML::Grove::Document or XML::Grove::Element:
12        $hash = $grove_object->get_ids($attr_name, $elements);
13
14        # Using an XML::Grove::IDs instance:
15        $indexer = XML::Grove::IDs->new($attr_name, $elements);
16        my $hash = {};
17        $grove_object->accept($indexer, $hash);
18

DESCRIPTION

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