GeoData holds the data model that is internally used for any geographic information which should be rendered. It deals whith the data only, drawing is performed elsewhere.
GeoDataDocument describes a document.
A model representation is built through parsing of files and creating a stack of GeoDataObject representing its data. The Geodata objects are all modeled after the Google KML files as defined in the KML documentation.
It is specialised in GeoDataParser to handle KML, GPX, GeoRSS and OSM formats and populate the data model. The parser relies on
To implement a new XML parser you need to
Each tag handler is called when the relevant XML tag is reached by the GeoParser ( which knows what tags to call by its registered tag list ). Each tag can access the stack data structure of the GeoParser as well as the Collection Data Structure of the GeoParser. This allows the tag handler to access items from the stack and allows root elements of the XML to add themselves to the collection data structure.
