    copied!<p>I have a bit of script that I think is nearly there. I have worked out a crude way of writing it, but I can't work out how to get it to function as a for loop.</p> <p>I am extracting data from an xml file that uses the following format:</p> <pre><code>&lt;Trackpoint&gt; &lt;Time&gt;2012-01-17T11:44:35Z&lt;/Time&gt; &lt;Position&gt; &lt;LatitudeDegrees&gt;51.920211518183351&lt;/LatitudeDegrees&gt; &lt;LongitudeDegrees&gt;26.706042898818851&lt;/LongitudeDegrees&gt; &lt;/Position&gt; &lt;AltitudeMeters&gt;-43.6026611328125&lt;/AltitudeMeters&gt; &lt;/Trackpoint&gt; &lt;Trackpoint&gt; &lt;Time&gt;2012-01-17T11:45:21Z&lt;/Time&gt; &lt;Position&gt; &lt;LatitudeDegrees&gt;51.920243117958307&lt;/LatitudeDegrees&gt; &lt;LongitudeDegrees&gt;26.706140967085958&lt;/LongitudeDegrees&gt; &lt;/Position&gt; &lt;AltitudeMeters&gt;-43.6026611328125&lt;/AltitudeMeters&gt; &lt;/Trackpoint&gt; </code></pre> <p>I can use the following to get say the LatitudeDegrees:</p> <pre><code>from xml.dom.minidom import parse doc = parse('/Users/name/Documents/GPS/gps.tcx') lat = doc.getElementsByTagName("LatitudeDegrees") time = doc.getElementsByTagName("Time") trackpoint = doc.getElementsByTagName("Trackpoint") for x in lat: print(x.firstChild.data) </code></pre> <p>but I would like to get the Lat, Long and time in order.</p> <p>I am guessing I need to use </p> <pre><code>for x in trackpoint </code></pre> <p>but the only way I can work out how to do that is as follows. </p> <pre><code>count = 0 n = len(trackpoint) while count &lt; n: print(time[count].firstChild.data) print(lat[count].firstChild.data) print(lon[count].firstChild.data) count += 1 </code></pre> <p>anyone have any ideas? I think I am just missing something really simple!</p>
