Subject: GPX to XML?

I have not touched XSLT since I retired. However I wish to convert some GPX 
files to a different XML format for my sat nav. I remember how picky XSLT 
can be...

Here is a simplified GPX source file:

<gpx xmlns="http://www.topografix.com/GPX/1/1";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; creator="komoot gpx 
writer" version="1.1"
xsi:schemaLocation="http://www.topografix.com/GPX/1/1 
http://www.topografix.com/GPX/1/1/gpx.xsd";>
<metadata>
<name>Tour</name>
 <desc/>
   <link href="http://www.komoot.de";>
     <text>komoot homepage</text>
     <type>text/html</type>
   </link>
</metadata>
<trk>
 <name>Tour</name>
   <trkseg>
     <trkpt lat="50.749345" lon="-2.3432386">
       <ele>53.85803985595703</ele>
       <time>2014-03-03T22:10:21Z</time>
     </trkpt>
     <trkpt lat="50.7494596" lon="-2.3445584">
       <ele>54.950225830078125</ele>
       <time>2014-03-03T22:10:45Z</time>
     </trkpt>
     <trkpt lat="50.7494921" lon="-2.3439906">
       <ele>53.61299514770508</ele>
       <time>2014-03-03T22:10:32Z</time>
     </trkpt>
    </trkseg>
  </trk>
</gpx>



XSLT file:


<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
version="1.0">
  <xsl:output method="xml" indent="yes"/>
      <xsl:template match="/">
          <routing_points>
             <default_set>
                <xsl:for-each select="gpx/trk/trkseg/trkpt">
                   <xsl:choose>
                      <xsl:when test="position() =1">
                      <xsl:element name="departure">
                            <lon><xsl:value-of 
select="floor(@lon*3600000)"/></lon>
                            <lat><xsl:value-of 
select="floor(@lat*3600000)"/></lat>
                         </xsl:element>
                     </xsl:when>
                     <xsl:when test="position() = last()">
                      <xsl:element name="destination">
                               <lon><xsl:value-of 
select="floor(@lon*3600000)"/></lon>
                              <lat><xsl:value-of 
select="floor(@lat*3600000)"/></lat>
                       </xsl:element>
                   </xsl:when>
                   <xsl:otherwise>
                      <xsl:element name="waypoint">
                            <lon><xsl:value-of 
select="floor(@lon*3600000)"/></lon>
                           <lat><xsl:value-of 
select="floor(@lat*3600000)"/></lat>
                    </xsl:element>
                  </xsl:otherwise>
                </xsl:choose>
             </xsl:for-each>
          </default_set>
      </routing_points>
  </xsl:template>
</xsl:stylesheet>







Result:

<routing_points>
           <default_set/>
</routing_points>

However if I remove: xmlns="http://www.topografix.com/GPX/1/1"; from the 
<gpx> node I get what I need:

Modified Result:

<routing_points>
           <default_set>
                       <departure>
                                   <lon>-8438367</lon>
                                   <lat>182698171</lat>
                       </departure>
                       <waypoint>
                                   <lon>-8440411</lon>
                                   <lat>182698054</lat>
                       </waypoint>
                       <destination>
                                   <lon>-8440584</lon>
                                   <lat>182697029</lat>
                       </destination>
           </default_set>
</routing_points>



I feel that editing a source file first is a bit like cheating. Please can 
anyone suggest what I should do?
