Domanda

La mia impostazione:

.
Compilatore: DMD 1.056
Libreria: Tango 0.99.9
OS: Windows 7
.
Cosa ho fatto finora:
Sono riuscito a costruire tramite API un file GPX e sapere come formattarlo e visualizzarlo sulla console.
.
Il mio codice:
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

Soluzione

auto to = new File ("copy.txt", File.WriteCreate);

to.write(print(gpxdoc));
to.close;

Apri il file e scrivi ad esso
