$doc = HTML::DOM->new;
$list = $doc->getElementsByTagName('p');
# returns an HTML::DOM::NodeList::Magic object

# ... return a list of items ...
$list->; # first node
$list->item(0); # same
$list->length; # same as scalar @$list
See HTML::DOM::NodeList both for a description and the API.
There is one difference, though: If you want to create a NodeList yourself, for
whatever reason, you can call the constructor shown in the synopsis. The
subroutine has to return the entire list that the node list is supposed to
contain. The second argument is the document to which the node belongs. If the
document is modified, the node list is automatically notified, and calls the
subroutine again the next time it is accessed, to reset itself. If you don't
provide the document, the node list will never be updated after the first time
an element is accessed.
