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