我的设置：
到目前为止我做了什么：
我已经设法通过API构建一个GPX文件，并知道如何格式化它并在控制台上显示它。
我的代码：
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;

问题：
如何将GPX（XML）文档保存到文件中？
答案 0 :(得分：1)
auto to = new File ("copy.txt", File.WriteCreate);
to.write(print(gpxdoc));
to.close;
打开文件并写入
