Version 1.1 and <link>

Download track from mapmytracks: comes in version 1.1 with no tags.

Because all trackpoints come on one single line, parse and to_xml() with gpxpy

now there are tags without values for every trackpoint and in other places.

Would it be possible to suppress them when they have no value?

I'm not 100% sure if I understand the problem. Can you provide a GPX file and the code to reproduce the problem?

download a track from mapmytracks.com - but I think this happens with any input, i also tried one from a different source. As long as the input version is 1.1 as in

<gpx xmlns="http://www.topografix.com/GPX/1/1"

then use this filter:

cat input.gpx | ./lf.py

and every trackpoint gets

lf.py is:

import sys
import gpxpy
gpx = gpxpy.parse(sys.stdin.read())
sys.stdout.write(gpx.to_xml())
sys.stdout.write('\n')

Unfortunately at the moment this would need a bigger refactory (the way the XML file is created. It should probably use a DOM builder, not string concatenation). I'll leave this issue open, but I don't have the time to fix it now.
