HTML::DOM::NodeList - Simple node list class for HTML::DOM
use HTML::DOM;
$doc = HTML::DOM->new;

This implements the NodeList interface as described in the W3C's DOM standard. In addition to the methods below, you can use a node list object as an array.
This class actually only implements those node lists that are based on array references (as returned by childNodes methods). The HTML::DOM::NodeList::Magic class is used for more complex node lists that call a code ref to update themselves. This is an implementation detail though, that you shouldn't have to worry about.
Returns the number of items in the array.
Returns item number $index, numbered from 0. Note that you call also use $list->[$index] for short.
