Detailed Description

Class to represent a node in a Document Object Model (DOM) tree structure.

A DOM is a structured document representation, in our case parsed from an XML stream (i.e. a file or a string). It is a tree structure in which each node has links to its children nodes and to its parent node (if it is not the root). This class serves as a base node corresponding to an XML tag that only contains attributes (no content for the tag itself).

Note: We reserve the use of the attribute "id" (all combinations of upper and lower case) for uniquely identifying an XML structure among its siblings. That is, we assume that this tag is unique among all siblings in an XML tree structure. If it is not unique, the user may not be able to correctly retrieve a node by function GetChildByID(), or to search for a node using Find() with a query string that is based on "id".
