DESCRIPTIONThe NodeList interface provides the abstraction of an ordered collection of nodes, without defining or constraining how this collection is implemented.
The items in the NodeList are accessible via an integral index, starting from 0.
Although the DOM spec states that all NodeLists are ``live'' in that they allways reflect changes to the DOM tree, the NodeList returned by getElementsByTagName is not live in this implementation. See CAVEATS for details.
- item (index)
- Returns the indexth item in the collection. If index is greater than or equal to the number of nodes in the list, this returns undef.
- The number of nodes in the list. The range of valid child node indices is 0 to length-1 inclusive.
Additional methods not in the DOM Spec
Removes all circular references in this NodeList and its descendants so the
objects can be claimed for garbage collection. The objects should not be used
