I'm trying to parse a GPX file . I tried it with JDOM, but it does not work very well. SAXBuilder builder = new SAXBuilder(); Document document = builder.build(filename); Element root = document.getRootElement(); System.out.println("Root:\t" + root.getName()); List<Element> listTrks = root.getChildren("trk"); System.out.println("Count trk:\t" + listTrks.size()); for (Element tmpTrk : listTrks) { List<Element> listTrkpts = tmpTrk.getChildren("trkpt"); System.out.println("Count pts:\t" + listTrkpts.size()); for (Element tmpTrkpt : listTrkpts) { System.out.println(tmpTrkpt.getAttributeValue("lat"

I am trying to use Pythons LXML library to create a GPX file that can be read by Garmin's Mapsource Product. The header on their GPX files looks like this <?xml version="1.0" encoding="UTF-8" standalone="no" ?> <gpx xmlns="http://www.topografix.com/GPX/1/1" creator="MapSource 6.15.5" 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/gpx.xsd"> When I use the following code: xmlns = "http://www.topografix.com/GPX/1/1" xsi = "http://www.w3.org/2001/XMLSchema-instance" schemaLocation = "http:/

Closed. This question is off-topic. It is not currently accepting answers. Learn more . Want to improve this question? Update the question so it's on-topic for Stack Overflow. Are there any Java libraries for parsing GPX files? I need to parse many GPX files into our own data structure (our own database). This question is too old and so do the answers. Thanks to the open source world, we have now jgpx, on google code ( forked multiple times on github ) and GPXParser, on sourceforge.net . There are also a lot of results for a search on Github . I'm not sure which one is more mature (one of them

I followed this example to parse a local GPX file in Android: http://android-coding.blogspot.pt/2013/01/get-latitude-and-longitude-from-gpx-file.html All works fine to access "lat" and "long" but I need also to get the "ele" value but all my tentatives were unsuccessful. Anyone can give me some hits to do that? Thanks in advance! Best regards, NR. you have the "Node node = nodelist_trkpt.item(i);" in your first loop. Get the child elements from this node an run through these child elements. e.g.: NodeList nList = node.getChildNodes(); for(int j=0; j<nList.getLength(); j++) { Node el = nList

I would like to continue the discussion from this post: GPX Schema validation problems . To go directly to the point, I want to ask how people are parsing and working with GPX files in their software or give me suggestions as to how one should do it. Although one may say, well just parse the trkpt elements and use them in your software, the things are not that simple for me. Firstly, as discussed in the cited post above, a lot of the gpx-producing-devices(software, gps-handheld-devices, etc) produce gpx files which do NOT conform to the official GPX schema(elements are laid-out in the wrong

I've got a GPS track produced by gpxlogger(1) (supplied as a client for gpsd ). GPS receiver updates its coordinates every 1 second, gpxlogger's logic is very simple, it writes down location ( lat , lon , ele ) and a timestamp ( time ) received from GPS every n seconds ( n = 3 in my case). After writing down a several hours worth of track, gpxlogger saves several megabyte long GPX file that includes several thousands of points. Afterwards, I try to plot this track on a map and use it with OpenLayers . It works, but several thousands of points make using the map a sloppy and slow experience. I
