## Interface DOMImplementationList

-     public interface DOMImplementationList

  The `DOMImplementationList` interface provides the abstraction of an ordered collection of DOM implementations, without defining or constraining how this collection is implemented. The items in the `DOMImplementationList` are accessible via an integral index, starting from 0.

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

  Since:
    DOM Level 3

    - #### item

          DOMImplementation item(int index)

      Returns the `index`th item in the collection. If `index` is greater than or equal to the number of `DOMImplementation`s in the list, this returns `null`.
      Parameters:
        `index` - Index into the collection.
      Returns:
        The `DOMImplementation` at the `index` th position in the `DOMImplementationList`, or `null` if that is not a valid index.
