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.
