Missing tag(s) during parsing

[tudorp]

Tried to parse a file with Python 3 looking as follows:
<?xml version='1.0' encoding='UTF-8'?> <gpx version='1.1' creator='GPSMID' xmlns='http://www.topografix.com/GPX/1/1'> <trk> <trkseg> <trkpt lat='40.61262' lon='10.592117'> <ele>100</ele> <time>2018-01-01T09:00:00Z</time> </trkpt> </trk> </gpx>

I noticed that the trk tags were missed due to the fact that the parsed node tag name looked like:
'{http://www.topografix.com/GPX/1/1}trk', which did not match trk

My workaround was to replace the original tag matching in method from_xml from class GPXField in file gpxfield.py:
if child.tag == self.tag:
with a regular expression that would match the tags while ignoring any prefix bound in curly brackets:
if re.match('^({[^{]*})?' + self.tag + '$', child.tag) is not None:

To be honest, I did not have the time to dig out why that prefix appeared on the tag...

Similar issue found for the elevation tag parsing in class GPXComplexField from same file. I implemented a similar workaround that solves the problem in my project

I just wrote a test in (eaef6a7) and there is definitely something weird happening here. Another strange thing is that if you change single to double quotes in xmlns.

<gpx version='1.1' creator='GPSMID' xmlns='http://www.topografix.com/GPX/1/1'>

to

<gpx version='1.1' creator='GPSMID' xmlns="http://www.topografix.com/GPX/1/1">

The test passes.

Fixed in dev, will be included in the next release.
