JPX 3.1.0 cannot extract TrackPointExtension

Nymerea commented 12 months ago

Here is an example of gpx file generated by amazfit device, it contains extension like speed or heart rate.

When using 3.1.0 version of jpx, the extension cannot be parsed.

<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>

Hi, I tried to reproduce it, but can't.

var gpxString = """
    <?xml version='1.0' encoding='UTF-8' standalone='yes' ?>

    """;

final GPX gpx  = GPX.Reader.of(Mode.LENIENT).fromString(gpxString);
final Document extensions = gpx
    .getTracks().get(0)
    .getSegments().get(0)
    .getPoints().get(0)
    .getExtensions().orElseThrow();

final NodeList trackPointExtension = extensions
    .getDocumentElement()
    .getFirstChild()
    .getChildNodes();

final String speed = trackPointExtension.item(0).getTextContent();
final String cad = trackPointExtension.item(1).getTextContent();
final String hr = trackPointExtension.item(2).getTextContent();

System.out.println("Speed: " + speed);
System.out.println("Cad: " + cad);
System.out.println("HR: " + hr);

The test above will produce the expected result of

Speed: 0.11750881
Cad: 0.0
HR: 88

That's my mistake because I saw [#document: null] in memory, I taught it was not parsable.

Sorry for the lose of time.
