Repairing a GPX Trace

Question

Today did a 9 mile walk and a lots of route as not been mapped into OSM. For some reason my garmin trace as a problem it won't open with my downloading software (memory map) it looks ok in a text editor, much like the dozens I've uploaded before,I tried memory card down load as well no luck. I have linux and windows available what could I chop or clean up this with and save as a GPX it was a nice walk but don't want to go there again for a while. I can use bing to map some but that is not ideal.any ideas

"Not well-formed (invalid token)" sounds like there's something in the XML that shouldn't be there.

I'd suggest you run the file through an online XML validator, such as this one. If there's a problem with the XML, it will tell you what it is.

Thanks Richard your link was so easy to use found the same faulty line as foxe but more detail.I edited to make it look like other lines' syntax in Notepad++ but then struggled to change file extension back from TXT to GPX. the file now opens ok and I will upload it tomorrow.very pleased thought i may have lost the trace.thanks also to Vclaw

@andy mackey: according to the Internet Archive's snapshot it is down since about Sept. 2015.

Instead, I would suggest to use the W3C Markup Validator.

Have you tried uploading the GPX to openstreetmap.org? Does it work, or does it give any sort of error?

Or you could try opening the GPX file in JOSM (without uploading it). If that works, you can then trace the path etc to add it to the map.

If these don't work, to try and fix the GPX you could:

Process it using GPXBabel. ie set the input and output formats to GPX, this might fix it.
Open it in an XML editor. Foxe is a good free option for Windows. This has syntax highlighting, so it should make it easier to spot any errors in the tags. It has an option to validate the file, which should warn of any errors in it.

found foxe a little awkward if I had tried harder I'm sure it would have done it

If I load a trace from switched on gps it can be a problem (as its still active)from a memory card it works better as its switched off

I just experienced a problem with a trace i couldn't open with my usual programmes. I then notice the memory on my Garmin Oregon's memory was full and it had stopped recording mid location. i should have saved and deleted stuff. I eventually opened the incomplete file with Notepad a text editor, i compared it with a good one, the last sentence was incomplete so i cut and pasted a good ending. so it ended like this:

<trkpt lat="52.0698085341" lon="-0.1248275572"></trkpt>
</trkseg>
</trk>
</gpx>

saved it and then it worked, apart from the fact the point was from a previous walk of course several KM away.
