Hello Nigel,

You can easily output XML from glpk using printf, see example below.

The same way you could create an Excel MHTML file. With multiple
worksheets if you want.

Best regards

# filename
param file, symbolic := 'random.xml';
# generate some data
set I := 1..10;
param p{I} := Uniform01();
# output data to xml
printf '<?xml version="1.0" encoding="ISO-8859-1"?>' > file;
printf '<resultset date="%s">',time2str(gmtime(),"%FT%TZ") >> file;
for {i in I}
  printf '<random index="%i">%g</random>',i,p[i] >> file;
printf '</resultset>' >> file;
end;
