Detailed Description

Wrapper around the underlying library for reading DOM elements (nodes).

A small wrapper class using an underlying library (currently QtXml) to read DOM nodes.
This class works with the individual nodes (DOM Elements), while the companion class InputDocument wrapper the whole document (DOM Document).
Note: In the DOM terminology "Elements" are a subset of the more general "nodes" (that include comments and other typologies..)
