GetRootElement

This function returns the root node for the element tree, called map. This represents the map node at the root of the XML document that contains map data.

This is a special element that is consistent across map changes. It is never destroyed and cannot be destroyed using destroyElement. It contains directly, or indirectly every other element in the map.

Syntax

element getRootElement ()

Returns

version = getElementData ( root, "version" )
