Using the script above gives me a trackPoint-element - Running >>> etree.tostring(trackPoint.find('{%s}extensions'% gpx_namespace)) '<extensions xmlns="http://www.topografix.com/GPX/1/1"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> \n<gpxx:TrackPointExtension xmlns:gpxx="http://gps.wintec.tw/xsd/"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://gps.wintec.tw/xsd http://gps.wintec.tw/xsd/TMX_GpxExt.xsd";> \n<gpxx:Temperature>26</gpxx:Temperature> \n<gpxx:Pressure>1020</gpxx:Pressure>\n</gpxx:TrackPointExtension> \n</extensions>\n' which is the subtree i'm looking for. I'd assume i can grab the contents of this with: ext_namespace = "http://gps.wintec.tw/xsd"; trackPoint.find('{%s}extensions'% gpx_namespace)).find('{%s} Temperature'% ext_namespace) But this is not correct, the result is 'None'. Imho this is exactly the same as further above where i extract lon,lat,altitude,..., besides that i don't use gpx_namespace but ext_namespace in the find(). Should the gpx_namespace be applied additionally to the ext_namespace in the extensions-subelements as it is a subelement of the gpx_namespace?
