Hi folks,I'm having a hard time figuring this one out. I have the following (snippet) of a GPX file:<gpx version="1.1" ...><trk><trkseg>
<trkpt lat="39.998454" lon="-105.086447">
<ele>1568</ele>
<time>2019-12-16T10:59:47.000Z</time>

<geotracker:meta s="0" />

<extensions>
<geotracker:meta c="0.03" s="1.83" />

</trkpt>......</trkseg></trk></gpx>Getting to the most of the nodes is easy:<?php
//open gpx file
$gpx = simplexml_load_file("Dec_16,_2019_3_59_47_AM.gpx");foreach ($gpx->trk as $trk) {
foreach ($trk->trkseg as $seg) {
foreach ($seg->trkpt as $pt) {
echo "lat: ", $pt["lat"], " lon: ", $pt["lon"];
echo " ele: ", $pt->ele, " time: ", $pt->time, "\n";
}
}
}
unset($gpx);?>But for the life of me, I can't figure out how to get information that's on the geotracker:meta line. Also note that not every single one of them will have both the 'c' and 's' attributes. Does anyone have any pointers pls?A
Converting it to array should make it easier for you:
