My setting:

Compiler: DMD 1.056
Library: Tango 0.99.9
OS: Windows 7

What I have done so far:

I have managed to build via API a GPX file and know how to format it and display it on the console.

My code:

module SwathGen;

import 
  tango.io.Stdout,
  tango.text.xml.Document,
  tango.text.xml.DocPrinter;

void main(char[][] args)
{   
    auto gpxdoc = new Document!(char);

    gpxdoc.header;

    gpxdoc.tree 
        .element(null,"gpx")
      .attribute (null,"xmlns","http://www.topografix.com/GPX/1/1")
      .attribute (null,"version","1.1")
            .attribute (null,"creator","SwathGen")
      .attribute (null,"xmlns:xsi","http://www.w3.org/2001/XMLSchema-instance")
      .attribute (null,"xsi:schemaLocation","http://www.topografix.com/GPX/1/1 http://www.topografix.com/GPX/1/1/gpx.xsd http://www.topografix.com/GPX/gpx_style/0/2 http://www.topografix.com/GPX/gpx_style/0/2/gpx_style.xsd http://www.topografix.com/GPX/gpx_overlay/0/3 http://www.topografix.com/GPX/gpx_overlay/0/3/gpx_overlay.xsd")
