Route issues about gpxpy

[tkrajina]

They are accessible, but they are not stored in default gpx fields because it's not part of the gpx standard. It's stored in extensions.

From the documentation:

gpx.py preserves GPX extensions. They are stored as ElementTree DOM objects.

gpx.routes[0].points[0].extension...

Hi
Thanks for fast reply, but from the debugger:

Not sure what's wrong, but here's a script I made for testing this:

g = gpxpy.parse(gpx) # gpx is your file
print(g.routes[0].points[0].extensions)
e = g.routes[0].points[0].extensions[0]
print(len(e))
node = e.getchildren()[1]
print(node.text)

The output is:

$ python q.py                                                                                                                                                     (v1.4.2)

Thanks again

When running your test code, I get

[<Element '{http://www.garmin.com/xmlschemas/TripExtensions/v1}ViaPoint' at 0x7fa1e29f47c0>, <Element '{http://www.garmin.com/xmlschemas/GpxExtensions/v3}RoutePointExtension' at 0x7fa1c85bbe00>]

I will do some further tests.

Route Test.TXT
That's my test file, just rename as GPX.

Looks like that none of the extensions has a children.

My code looks like:
` gpx_file = open('Route.Test.GPX', 'r')

    gpx = gpxpy.parse(gpx_file)
    if len(gpx.routes) == 0:
        return None

    print(gpx.version)

    print(gpx.routes[0].points[0].extensions[0])
    e = gpx.routes[0].points[0].extensions[0]
    print(len(e))
    for node in e.getchildren():
        print(node.text)`

Output is:

That error doesn't say that there are no children, just that Element has no getchildren() method. But note that the third line says 3 and that's len(e). So there are 3 children nodes, you just need to iterate through them (without getchildren).

g = gpxpy.parse(gpx)
print(g.routes[0].points[0].extensions)
e = g.routes[0].points[0].extensions[0]
print(len(e))
for node in e:
    print(node.text)

You are absolutely right.
Thanks a lot.
Sorry for disturbing and thanks for the great library.
