Usage

<script src="omx2gpx.js"></script>
<script>
  const omxparser = new OMXParser();
  omxparser.addData(omh_data); // omh_data is the content of the .OMH file
  omxparser.addData(omd_data); // omd_data is the content of the .OMD file
  if (omxparser.valid) {
    console.log(omxparser.toGPX());
  }
</script>

You can also bypass the .OMH (header) loading but beware, the GPX file won't any have valid date.

const omxparser = new OMXParser();
omxparser.addData(omd_data); // omd_data is the content of the .OMD file
if (omxparser.containspoints) {
  console.log(omxparser.toGPX());
}
