DOM Level 3.0 ElementTraversal Robin Berjon robin.berjon@expway.fr http://berjon.com/ Expway http://expway.com/
Abstract

The ElementTraversal specification defines a small set of shortcut accessors used while navigating the structure (i.e. elements) of a DOM. While it does not expose information previously unavailable, it has been designed to help authors avoid mistakes commonly found programs that manipulate the DOM and is well-suited for implementation in mobile devices where it may be impossible to support the entirety of the DOM.
