So I’m trying to get the coordinates from an GPX file via regex.

The file:

<?xml version="1.0" encoding="UTF-8"?>
<gpx
  version="1.1"
  creator="Runkeeper - http://www.runkeeper.com"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns="http://www.topografix.com/GPX/1/1"
  xsi:schemaLocation="http://www.topografix.com/GPX/1/1 http://www.topografix.com/GPX/1/1/gpx.xsd"
  xmlns:gpxtpx="http://www.garmin.com/xmlschemas/TrackPointExtension/v1">
<wpt lat="37.778259000" lon="-122.391386000"><ele>3.4</ele><time>2016-06-17T23:41:03Z</time><extensions><gpxtpx:TrackPointExtension><gpxtpx:hr>171</gpxtpx:hr></gpxtpx:TrackPointExtension></extensions></wpt>
<wpt lat="37.778194000" lon="-122.391226000"><ele>3.4</ele><time>2016-06-17T23:41:13Z</time><extensions><gpxtpx:TrackPointExtension><gpxtpx:hr>171</gpxtpx:hr></gpxtpx:TrackPointExtension></extensions></wpt>
<wpt lat="37.778297000" lon="-122.391174000"><ele>3.4</ele><time>2016-06-17T23:41:18Z</time><extensions><gpxtpx:TrackPointExtension><gpxtpx:hr>171</gpxtpx:hr></gpxtpx:TrackPointExtension></extensions></wpt>
<wpt lat="37.778378000" lon="-122.391117000"><ele>3.4</ele><time>2016-06-17T23:41:23Z</time><extensions><gpxtpx:TrackPointExtension><gpxtpx:hr>171</gpxtpx:hr></gpxtpx:TrackPointExtension></extensions></wpt>
<wpt lat="37.778449000" lon="-122.391039000"><ele>3.4</ele><time>2016-06-17T23:41:26Z</time><extensions><gpxtpx:TrackPointExtension><gpxtpx:hr>171</gpxtpx:hr></gpxtpx:TrackPointExtension></extensions></wpt>
<wpt lat="37.778525000" lon="-122.390942000"><ele>3.4</ele><time>2016-06-17T23:41:29Z</time><extensions><gpxtpx:TrackPointExtension><gpxtpx:hr>171</gpxtpx:hr></gpxtpx:TrackPointExtension></extensions></wpt>
</gpx>

My regex:

"<wpt lat="(.*)" lon="(.*)">"g

My Code:

List<String> allMatches = new ArrayList<String>();
        Matcher m = Pattern.compile(regex)
                .matcher(gpxString);
        while (m.find()) {
            allMatches.add(m.group());
        }

For some reason the size of allMatches is 0. I checked the regex using an online tool, but the tool has no Problem finding the matches.

Whats wrong here?
