is there a way to it gpx to parse the garmin extension?

[rful011]

Hi

I need to parse some gpx files from a Garmin Etrex 30 which have some data the extension that I need. The schemas are available.
I have had a brief look at the code but I can't figure out any way of getting data out.

Hi @rful011 - we don't currently support any extended schemas. Do you have a link to the Garmin schema that I can take a look at?

here is the start of the xml file which lists the schema <?xml version="1.0" encoding="UTF-8" standalone="no" ?> <gpx xmlns="http://www.topografix.com/GPX/1/1" xmlns:gpxx="http://www.garmin.com/xmlschemas/GpxExtensions/v3” xmlns:wptx1="http://www.garmin.com/xmlschemas/WaypointExtension/v1” xmlns:gpxtpx="http://www.garmin.com/xmlschemas/TrackPointExtension/v1" creator="eTrex 30" version="1.1” xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.topografix.com/GPX/1/1 <http://www.topografix.com/GPX/1/1> http://www.topografix.com/GPX/1/1/gpx.xsd http://www.garmin.com/xmlschemas/GpxExtensions/v3 <http://www.garmin.com/xmlschemas/GpxExtensions/v3> http://www8.garmin.com/xmlschemas/GpxExtensionsv3.xsd http://www.garmin.com/xmlschemas/TrackStatsExtension/v1 http://www8.garmin.com/xmlschemas/TrackStatsExtension.xsd <http://www8.garmin.com/xmlschemas/TrackStatsExtension.xsd> http://www.garmin.com/xmlschemas/WaypointExtension/v1 http://www8.garmin.com/xmlschemas/WaypointExtensionv1.xsd http://www.garmin.com/xmlschemas/TrackPointExtension/v1 http://www.garmin.com/xmlschemas/TrackPointExtensionv1.xsd”> I am a halfway competent ruby coder but not really familiar with XML but I have to get to grips with it for some stuff at work which involves parsing huge xml documents (order of GB so I am trying to find my way around SAX). Anyway if you give me some pointers I will have a go at adding it myself. At the moment I have no idea where to start! Russell.

Hi Andrew I have spent several hours now fiddling with nokogiri and the gpx code and now understand pretty well how it works. It turns out that gpx is extracting the data out of the extension but not the tags. Just using nokogiri I got puts wp_element.at('extensions’) gives <extensions> <wptx1:WaypointExtension> <wptx1:Samples>2</wptx1:Samples> </wptx1:WaypointExtension> </extensions> while gpx returns the value 2 for the essentially the same code (evaluation in a scalar context?). Anyway I was wondering if the easiest way of dealing with extension would be to provide a callout and pass it the extension element and return the value as the value. I.e allow the user to deal the format of the extension. Russell
