I'm thrashing around in the dark here, trying to read the 'ele' tags in a GPX
file. This cobbled together code from bits and pieces doesn't get anywhere
near working but I can't find actual examples anywhere, or help with the
API.
The map itself is quite successful for showing (and toggling) gpx tracks,
and displaying the lengths. See wed-slow-fast27mar.htm
<http://www.carnethy.com/maps/wed_training/2013/iframecontent/wed-slow-fast27mar.htm>
but I'd now like to add the total ascents as well.
var runslow = "../gpx/wed-slow-06feb13.gpx"
read: function (runslow){
//(and what is this if clause for??)
if (typeof runslow == "string") {
runslow = OpenLayers.Format.XML.prototype.read.apply(this, [runslow]);
}
var ascent = null;
var eles = runslow.getElementsByTagName("ele");
for (var i=0, len=eles.length; i<len; i++) {
if (eles[i] > eles[i-1])
ascent = ascent + (eles[i] - eles[i-1]);
}};
