Bug#1109596: gpsprune: generates an invalid GPX file: invalid XML due to duplicate attributes

[Vincent Lefevre]

Package: gpsprune
Version: 25.2-1
Severity: normal

When exporting to GPX, gpsprune generates an invalid GPX file:
this is invalid XML due to duplicate attributes. In particular,
viking cannot open the file due to this.

The beginning of the file is

<?xml version="1.0" encoding="UTF-8"?>
<gpx version="1.1" creator="GpsPrune v25.2 activityworkshop.net"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns="http://www.topografix.com/GPX/1/1"
 xsi:schemaLocation="http://www.topografix.com/GPX/1/1  http://www.topografix.com/GPX/1/1 http://www.topografix.com/GPX/1/1/gpx.xsd https://osmand.net  https://osmand.net/docs/technical/osmand-file-formats/osmand-gpx "
 xmlns:x="http://www.gpsessentials.com/ns/gpx-ext/1/0"
 xmlns:osmand="https://osmand.net"
 xmlns:gpxtpx="http://www.garmin.com/xmlschemas/TrackPointExtension/v1"
 xmlns:osmand="https://osmand.net/docs/technical/osmand-file-formats/osmand-gpx"
 xmlns:gpxtpx="https://www8.garmin.com/xmlschemas/TrackPointExtensionv1.xsd"
>

As you can see, xmlns:osmand and xmlns:gpxtpx are duplicate
(with different values).

Fortunately, this is easy to correct after the file generation:
removing the last two attributes solves the issue for viking.
