tinyxml2::XMLNode class
XMLNode is a base class for every object that is in the XML Document Object Model (DOM), except XMLAttributes. Nodes have siblings, a parent, and children which can be navigated. A node is always in a XMLDocument. The type of a XMLNode can be queried, and it can be cast to its more defined type. A XMLDocument allocates memory for all its Nodes. When the XMLDocument gets deleted, all its Nodes will also be deleted. @verbatim A Document can contain: Element (container or leaf) Comment (leaf) Unknown (leaf) Declaration( leaf ) An Element can contain: Element (container or leaf) Text (leaf) Attributes (not on tree) Comment (leaf) Unknown (leaf) @endverbatim
