## Interface NameList

-     public interface NameList

  The `NameList` interface provides the abstraction of an ordered collection of parallel pairs of name and namespace values (which could be null values), without defining or constraining how this collection is implemented. The items in the `NameList` are accessible via an integral index, starting from 0.

  See also the Document Object Model (DOM) Level 3 Core Specification.

  Since:
    DOM Level 3
