Hi all,
I need a small example on how to read all the "lat" and "lon" values in
a xml document like this one:

<?xml version="1.0"?>
<gpx version="1.0" creator="http://www.gnuite.com/cgi-bin/gpx.cgi"
xmlns="http://www.topografix.com/GPX/1/0">
   <trk>
     <trkseg>
       <trkpt lat="45.5238" lon="-122.67501">
          <desc>Head east from Northwest Couch Street. Go 0.2
miles.</desc></trkpt>
       <trkpt lat="45.52382" lon="-122.67441"/>
       <trkpt lat="45.52383" lon="-122.67339"/>
     </trkseg>
   </trk>
</gpx>

thanks

var
        xd: IXMLDocument;
        nl: IXMLNodeList;
        I: Integer;
begin
        xd := LoadXMLData(
'<?xml version="1.0"?>'+
                '<gpx version="1.0" creator="http://www.gnuite.com/cgi-bin/gpx.cgi"

                '                       <trkpt lat="45.5238" lon="-122.67501">'+
                '                                <desc>Head east from Northwest Couch Street. Go 0.2
