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.
