XML documents can be seen as an hierarchic data structure defined by a set of nested tags and data.

This class implements an abstraction that allows creating and accessing XML documents as an hierarchy of objects. The object variables are mapped to XML tag names and variable values to XML tag data. The object variables can be set or updated to change the XML document contents.

Regenerating an updated XML document is a matter of calling a function to generate XML tags starting from the root object of the hierarchy. Loading a new XML document can be done passing the XML data to the class constructor.

This object oriented approach makes it simpler to create and update XML documents of any complexity.

Detailed description

This class can be used to create and manipulate hierachical objects that can be stored and retrieved from XML documents.

The class provides means to define an object and their property values, as well to add children object and so dynamically build an hierarchy of objects.

The class can generate XML documents that represent the hierarchy defined by an object and its children objects.

The class constructor allows passing XML data from which it is read the definition of its properties and eventual children objects.
