The 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.
A NodeList returned from a method must be released with a call to release() when no longer needed.

virtual Node * item(
unsigned long index
) const = 0;
Returns the index'th item in the collection. If index is greater than or equal to the number of nodes in the list, this returns null.
virtual unsigned long length() const = 0;
Returns the number of nodes in the list. The range of valid node indices is 0 to length - 1 inclusive.
