Re: <extensions> tag in gpx files (Bill Park)

[Bill Park-2]

HI,
Thanks for the prompt reply.

I am running the 1.4.3 beta version as I noted it was better at handling 1.1
GPX.

This is the command I am using:
gpsbabel -w -r -t -i
gpx,suppresswhite=0,logpoint=0,gpxver=1.1,humminbirdextensions=0,garminexten
sions=0 -f D:\Bill\Documents\Testing\GPX File Compatability\GPX 005.gpx -o
gpx,suppresswhite=0,logpoint=0,gpxver=1.1,humminbirdextensions=0,garminexten
sions=0 -F D:/Bill/Documents/Testing/GPX File Compatability/GPX 005_b.gpx

I am not very good with XML so do not understand what you mean when you say
the input is not valid. I have opened it in XML Notepad 2007 and Textpad and
it looks OK.
I assume the people who supplied the file believe it is valid xml so if you
can point me in right direction I will go back to them and suggest they fix
it.

<extensions> are only supported in GPX 1.1   Our old writer defaults to 1.0
and generally makes a mess of 1.1 input when it writes it as 1.0.  The new
one does a better job of guessing when there's only a single input.

The data you provided isn't actually valid XML; it's in some multi-byte
encoding.
You didn't include the commands you actually issued.
You didn't mention what version you tried, so we don't know if you're
working with the old writer in 1.4.2 or the new one in the beta for 1.4.3

But even with all that, we're still going to work pretty hard to preserve,
not drop <extensions> as they're part of GPX, so we may not be the tool for
you anyway...
