DOMStringList

```
public interface DOMStringList
```
The DOMStringList interface provides the abstraction of an ordered collection of DOMString values, without defining or constraining how this collection is implemented. The items in the DOMStringList are accessible via an integral index, starting from 0.
See also the Document Object Model (DOM) Level 3 Core Specification.

Since:

1.5, DOM Level 3
