DESCRIPTION

The Web::DOM::NamedNodeMap class implements the DOM NamedNodeMap interface, i.e. it represents the list of the content attributes of an element.

METHODS

Following methods are available:

$node = $col->{$name}

$node = $col->get_named_item ($name)

Return the first node in the list whose name is equal to the argument. [DOM] [DOMPERL]

$node = $col->get_named_item_ns ($nsurl, $local_name)

Return the node in the list whose namespace URL and local name are equal to the arguments. [DOM]

This method is only applicable to the attributes collection. [DOMDTDEF]

$node = $col->[$index]

$node = $col->item ($index)

Return the node in the collection, specified by its index. [DOM] [DOMPERL]

Use of the item method is discouraged as it doesn't support Perlish ways to access items, such as negative indexing, while $col->[-1] works as you intended.

$number = @$col

$number = keys %$col

$number = $col->length

Return the number of the nodes in the collection. [DOM] [DOMPERL]

$node = $col->remove_named_item ($name)

Remove the first node in the list whose name is equal to the argument. The removed node is returned. [DOM]

$node = $col->remove_named_item_ns ($nsurl, $local_name)

Remove the node in the list whose namespace URL and local name are equal to the arguments. The removed node is returned. [DOM]

This method is only applicable to the attributes collection. [DOMDTDEF]

$node = $col->set_named_item ($node)

$node = $col->set_named_item_ns ($node)

Add the specified node to the list. If there is already a node with same name in the list, the node is removed from the list and is returned. Otherwise undef is returned. [DOM]

The set_named_item_ns method is only applicable to the attributes collection. [DOMDTDEF]

$arrayref = $col->to_a

Return the new static array reference containing the nodes in the collection. [DOMPERL]

($node1, $node2, ...) = $col->to_list

($node1, $node2, ...) = @$col

Return the list of the nodes contained in the collection. [DOMPERL]

The object supports Perl standard read-only operations for array references, e.g. exists $col->[4] or for hash references, e.g. exists $col->{class}. [DOMPERL]
