Kml Gpx Reader

The program extracts information from the KML or GPX file by parsing the words
LineString and coordinates. Usually, there is ONLY ONE section for coordinates.
However, if there is more than one section a list of all the sections will be shown.
Furthermore, if no height data is included, the list will be empty and the graph will not
show any data.
If you find a KML or GPX that the program does not read
plz send it to me. Thanks
