Subject: error with Geo:Gpx

hi, i just started working with your Geo:Gpx module (v0.18) i want to read and manipulate existing GPX files. but i cant start working with it: reading from file doesn't work: my $gpx = Geo::Gpx->new( xml => $params{gpx_file_path} ); ---> not well-formed (invalid token) at line 1, column 0, byte 0 at /usr/local/share/perl/5.8.4/XML/TokeParser.pm line 353 then i try to use a filehandle my $gpx = Geo::Gpx->new( input => $fh ); ---> Can't call method "get_token" on an undefined value at /usr/local/share/perl/5.8.4/XML/Descent.pm line 62, <GEN0> line 235. all dependencies are installed (XML:Descent etc...) i tried the above statements with several GPX files (even that simple one from wikipedia) so the cause should be not the data. i wanted to check http://rt.cpan.org/ first, but the site is down. can u help me oder give a hint to solve this problem? thanx, ulf -- ulf treger // gestaltung und visuelle kommunikation ulf.treger@dekoder.de // http://buero.dekoder.de tel +49 (0)40 391 986 - 56 // fax - 70 mobil +49 (0)173 233 64 46 // skype ulf_t pgp public key (DH/DSS) 0x43402E1D // 2048 bytes büro 3+x // gaußstraße 25b // d-22765 hamburg

Sounds as if the file you're trying to parse is invalid in some way. Could you mail it to me (andy /at/ hexten /dot/ net) or attach it here please?

hi andy, thanks for reply. i used several gpx-files for testing. test1.gpx --> sample taken from http://en.wikipedia.org/wiki/GPX test.gpx --> file found somewhere osm.gpx --> one of my gpx files best, ulf -- ulf treger // gestaltung und visuelle kommunikation ulf.treger@dekoder.de // http://buero.dekoder.de tel +49 (0)40 391 986 - 56 // fax - 70 mobil +49 (0)173 233 64 46 // skype ulf_t pgp public key (DH/DSS) 0x43402E1D // 2048 bytes büro 3+x // gaußstraße 25b // d-22765 hamburg

hi andy, it works for me also. and your lines gave me the hint to solve the problem. i interpreted the documentation wrong: the two ways... my $gpx = Geo::Gpx->new( xml => $gpx_document ); my $gpx = Geo::Gpx->new( input => $fh ); ...i read (and tested negative) as... my $gpx = Geo::Gpx->new( xml => [path/to/gpx-file] ); my $gpx = Geo::Gpx->new( input => $filehandle ); so, now i have: open(FH, "<test1.gpx") || die; my $gpx = Geo::Gpx->new( xml => join '', <FH> ); close FH; and that works fine! i wonder, it could be a good idea to add this way of accessing the xml data to your documentation? thanks a lot for your hint + sorry for bothering you. best, ulf -- ulf treger // gestaltung und visuelle kommunikation ulf.treger@dekoder.de // http://buero.dekoder.de tel +49 (0)40 391 986 - 56 // fax - 70 mobil +49 (0)173 233 64 46 // skype ulf_t pgp public key (DH/DSS) 0x43402E1D // 2048 bytes büro 3+x // gaußstraße 25b // d-22765 hamburg

Yes, I think the documentation could be clearer - and the diagnostics more helpful. Show quoted text
