Read GPX file

Read all track points and waypoints and put them into arrays

INPUT:

GPX file name (and path)

PROCESS:

Convert XML to DOM data
Track points: Extract latitude, longitude, elevation and time
Way points: Extract latitude, longitude, elevation, time and name

OUTPUT:

Track points: double array [latitude, longitude, elevation] and cell vector {time}
Way points: double array [latitude, longitude, elevation] and cell array {time, name}

If an elevation is not present, this elevation is set to zero.

If a time or name is not present, this time or name is set to empty.

If any lat, lon, elev. is not a number, 'CORRUPT GPX FILE!' is returned for the first way point name.

Write GPX file

Function to write a GPX file with given track and way points.

INPUT: DataGPX, a struct with the fields:

fileName: string, default 'MyGPX' + date
header: string with header information, default: 'version="1.1" xmlns="http://www.topografix.com/GPX/1/1"'
wpts: lat, lon, ele, double nwpt x 3 or nwpt x 2, nwpt is number of way points, default: no way points
default for elevation: 0
wptTime: time of a way point, cell array nwpt x 1, default: no way point time
wptName: name of a way point, cell array nwpt x 1, default: no way point name
trkName: name of total track, string, default: file name
trkPts: lat, lon, (ele), double ntrk x 3 or ntrk x 2, ntrk is number of track points, default: no track points
default for elevation: 0
trkTime: time of a trk point, cell array ntrk x 1, default: no track time

All fields are optional
